2 Introduction

2.1 NPT-1020 Platform Layout The NPT-1020 is a packet transport platform for the access, offering an All-Native solution that optimizes both TDM and packet handling. The NPT-1020 is a cost-effective choice for the first aggregation stage, geared for cellular tail locations (3G and LTE), providing a unique hybrid solution for high capacity access rings, and optimized for popular triple play applications.

As Packet Optical Access (POA) platform with enhanced MPLS-TP support, the NPT-1020 is designed around a centralized hybrid matrix card that supports any-to-any direct data card connectivity as well as native TDM switching capacity. The NPT-1020 offers a packet switching capacity of up to 10 Gbps or 60 Gbps (with a choice of two modes on the same unit) as well as a TDM capacity of up to 2.5G (16 x VC4 fully low order traffic).

The platform offers non-traffic-affecting upgrades from 1G-based configurations to 10GE-based (with up to 4 x 10GE interfaces) through the CPS50 card, a central packet switch (CPS) Tslot card for the NPT-1020. This card provides scalable upgrade with high capacity 10GE configuration to the NPT-1020. The CPS50 makes it possible to upgrade the system packet switching capacity to 60 Gbps, supporting up to 2 × 10GE (SFP+) and 2 flexible SFP houses (each can support 1 × 10GE with SFP+, or 1 × GE with SFP, or 2 × GE with CSFP).

The NPT-1020 offers enhanced MPLS-TP data network functionality, including the complete range of Ethernet-based services (CES, EoS, MoT, MoE, and PoE+) (see MPLS-TP and Ethernet Solutions).

The NPT-1020 is a compact (1U) base platform housed in a 243 mm deep, 465 mm wide, and 44 mm high equipment cage with all interfaces accessible from the front of the unit. The platform includes the following components:

Traffic processing modules:

21 built-in native E1s

14 ports, divided between:

2 x STM1/STM4 ports (native)

4 x 10/100/1000BaseT electrical ports (PoE+)

4 x 10/100/1000BaseT electrical ports

4 100/1000 FX/GE optical ports

1 traffic card slot (Tslot)

Redundant or non-redundant power supply modules (INF)

Figure 2-1: NPT-1020 platform

NPT-1020 Installation and Maintenance Manual Introduction


The NPT-1020 can be fed by 24 VDC, -48 VDC, or 94-240 VAC. In DC power feeding, two INF modules can be configured in two power supply module slots for redundant power supply, or one double slot INF module with dual-feeding can be configured. AC power feeding requires the use of a conversion module to implement AC/DC conversion.

The NPT-1020 can be installed in 2,200 mm or 2,600 mm ETSI racks or in 19” racks. The rugged platform design also makes this platform suitable for street cabinet use, withstanding temperatures up to 70°C.

The NPT-1020 can also be configured as an expanded platform, when combined with the EXT-2U expansion unit, as illustrated in the following figure.

Figure 2-2: NPT-1020 platform with expansion unit

Typical power consumption for the NPT-1020 is 50 W. Power consumption is monitored through the management software. For more information about power consumption requirements, see the NPT Installation and Maintenance Manual and the NPT System Specifications.

2.2 EXT-2U Expansion Unit The EXT-2U platform is a high density modular expansion unit for the NPT's multiservice metro access platform series. It supports the complete range of native and hybrid PCM, TDM, PDH, SDH, and Ethernet interfaces. All traffic processing, cross-connect, packet switching, timing and synchronization, control and communication and main power supply functions are performed by the corresponding system in the base unit on which expansion unit is installed. Integrating this add-on platform into your network configuration is not traffic-affecting.

NOTE: The EXT-2U expansion unit can be combined with the NPT-1020, NPT-1021, NPT-1050, NPT-1200, and NPT-1800 platforms. For easier reading, the slot layout is not repeated in the sections describing each of those platforms. The reader is simply referred back to this slot layout description.

Figure 2-3: EXT-2U platform

The EXT-2U expansion unit is housed in a 243 mm deep, 465 mm wide, and 88 mm high equipment cage with all interfaces accessible from the front of the unit. Expansion units include their own independent power supply and fan unit, for additional reliability and security. The platform includes the following components:

NPT-1020 Installation and Maintenance Manual Introduction


Three multipurpose slots (ES1 to ES3) for any combination of extractable traffic cards. PCM, TDM, ADM, Ethernet, and CES traffic are all handled through cards in these traffic slots. All interfaces are configured through convenient SFP modules, supporting up to 2.5G or 2GbE traffic per slot. Each slot in the EXT-2U has a TDM capacity of up to 16 x VC-4s; the total capacity of the EXT-2U is 48 x VC-4s.

Two slots for INF power supply units. There are two units for system redundancy. Note that INF modules are extractable in the EXT-2U.

One FCU fan unit consisting of multiple separate fans to support cooling system redundancy.

The following figure depicts the EXT-2U platform layout.

Figure 2-4: EXT-2U slot layout

In the DC power supply, the maximum power consumption of the NPT-1020 is 55 W.

For AC power supply, configure an external AC/DC converter.

NOTE: If the planned power consumption of the equipment installed in the platform is 80% or more of the maximum listed value, it is recommended to consult ECI Customer Support.

3.3 Tools and Test Equipment No special-purpose tools beyond a standard technician’s toolbox are required for the installation of NPT-1020 platforms.

Traffic cables can be prepared on site, so make sure suitable tool kits are available. They include tools for the assembly of coaxial cables as listed in the following table, and tools for the preparation of optical patch cords.

3.3.1 Cleaning Optical Connectors When handling optical fibers, clean the optical connectors with the standard cleaning kits recommended by the manufacturers.

3.4 Installing the NPT-1020 in Racks The following sections describe options for installing the NPT-1020 in racks with corresponding ancillary equipment.

3.4.1 Installation Plan Follow these guidelines for installing NPT-1020 platforms and ancillary equipment in racks.

We recommend installation in ECI ETSI racks, which provide the following advantages:

Removable rear and side panels, enabling tidy leading and efficient maintenance of all rack cables, including:

PCM/E1/E3/DS-3/STM-1e cables

Control cables

Power cables

Data cables

Voice frequency cables

Timing cables

Two ducts on the rack’s front rails for routing up to 200 optical fibers

Open frame top and bottom, facilitating easy leading of cables from suspension floors and/or ceiling ladders

Front door mountable for left or right opening

NPT-1020 equipment racks can be installed on wooden, concrete, or floating floors, or suspended from overhead mountings.



3.4.2 Typical NPT-1020 Installation For a typical installation of a NPT-1020 shelf in an ECI’s ETSI rack, see Typical installation in of a single NPT-1020 in an 2200 ETSI rack.

In addition to the NPT-1020 itself, the equipment installed in the rack includes:

One RAP installed at the top of the rack. The RAP is used to connect external power and alarm monitoring lines (RAP-4B only) to the NPT-1020 shelves installed in the rack. The RAP fully supports up to four shelves with dual power feeding or eight shelves with single power feeding. In addition to the space needed for RAP installation, you must leave at least 50 mm of free space under the RAP for cable routing.

NOTE: The RAP-BG does not support alarm monitoring lines.

Fiber Storage Tray. A separate FST can be installed for each NPT-1020 with optical modules. Each FST contains two storage reels, enabling the fiber to be stored on the right or left side of the tray. Leave at least 50 mm of free space between the NPT-1020 shelf and its FST, and another 50 mm free between the FST and the next NPT-1020 shelf.

xDDF-21. When unbalanced E1 interfaces are needed, the xDDF-21 should be installed with the NPT-1020. Each xDDF-21 can support 21 channels of E1. The xDDF-21 can be installed anywhere on the same rack on which the NPT-1020 shelf is installed, or on another rack.

ICPs for the SM_10E/EM_10E, including ICP_VF, ICP_V24, ICP_V24F, ICP_V11_V24, and ICP_V35. When PCM interfaces are provided by the SM_10E/EM_10E, the corresponding ICPs can be installed in order to simplify installation and connection to customer termination equipment. Each ICP can support one SM_10E/EM_10E traffic module. ICPs can be installed anywhere on the same rack on which the NPT-1020 shelf is installed, or on another rack.

3.4.3 Integrating NPT-1020 Platforms and Other Equipment in One Rack

When NPT-1020 platforms and associated accessories do not occupy the entire rack, additional equipment can be installed in the remaining rack space. Make sure that any heat generated by this equipment can be dissipated efficiently, and that thermal isolation is provided between the various equipment units.

In the event of additional equipment being installed in the rack, contact ECI’s Customer Support team for assistance.

3.5 Preparing Cables and Fibers

NOTE: This section provides information for preparing cables and optical fibers. The necessary cables can be ordered from ECI. For details, contact ECI’s Customer Support team or your ECI sales representative.

Before you start:

The following main types of cables are required for installing the NPT-1020:

Grounding cables

DC power cables (RAP Input Power Cables and Platform Power Cables)

Alarm cables

Management cables

Timing (clock) cables

Optical fibers

Electric traffic cables



Some of these cables are supplied as part of the NPT-1020 equipment, while others must be prepared on site or ordered separately from ECI.

In the following sections, you will find information about the cables, and how to prepare them on site, where relevant. For details about the equipment connector types and cable wiring, see Connection Data.

WARNING: When preparing cables, in particular power and grounding cables, use only UL-listed components of the specified types. Components must also comply with any applicable national and local safety codes and regulations.

Only qualified trained personnel may be involved in the preparation of the various cable types. Personnel must use only approved procedures, in accordance with the applicable workmanship practice.

3.5.1 Grounding Cables Platform grounding is achieved by connecting the platform to the rack using rack mounting brackets. Grounding is provided by contact when the unit is fastened to the rack.

A reliable low-impedance connection must be provided using copper conductors between the rack frame and the site grounding bus.

Make the connection between the rack grounding screw and the site grounding bus with a 2 AWG (35 mm2) or thicker copper lead with yellow/green insulation, in compliance with UL/ETSI recommendations.

Route grounding conductors along the shortest possible route. Treat the bare portion of the conductor with antioxidant and connect a listed two-hole compression lug. If the lug is not plated, polish it until it has a bright finish and coat it with antioxidant before connecting it to the frame of the rack. Do not mix different types of metal conductors.

3.5.2 DC Power Cables DC power cables must be prepared on site. Two types of DC power cables are needed:

RAP input power cables

Platform power cables

ECI recommends the use of shielded power cables for DC power connections, with the shields connected to the frame ground at the rack end only.

3.5.2.1 RAP Input Power Cables The RAP input power cables are prepared on site. They connect input power from the site power distribution subsystem to the DC input terminals of the RAP.

Two input power cables are required for each rack, one for each source. The cables must use copper leads complying with UL/ETSI recommendations. Use a red lead for the positive conductor and a black lead for the negative conductor. The RAP cable ends must be terminated in M6 cable lugs matching the conductor gauge.



The recommended cable gauge is 25 mm² or thicker. This gauge ensures that the voltage drop across the rack power cable does not exceed 2 V, even for cable runs of maximum 30 meters connected to a RAP and providing power to multiple NPT-1020 platforms.

When the RAP is used to provide power to a single NPT-1020 platform, lower-lead gauges may be used, as follows:

For runs not exceeding 20 meters, use 10 mm2 copper leads.

For runs not exceeding 30 meters, use 16 mm2 copper leads.

3.5.2.2 Platform Power Cables One 12 AWG cable, supplied by ECI, connects the input power from the rack RAP unit to the POWER IN connector on each INF-1020 module of each NPT-1020 platform installed in the rack.

3.5.3 Alarm Cables Alarm cables used within NPT-1020 equipment are included in the shipment according to the site specifications.

The alarm indications are carried by the shelf alarm indication cable. One shelf alarm indication cable is required for each NPT-1020 shelf installed in the rack. This cable connects between the ALARM connector on the NPT-1020 and one of the ALARMS connectors on the RAP (RAP-4B only). Cable length is 2.0 m.

NOTE: There are no ALARMS connectors on the RAP-BG.

3.5.4 Management Cables Out-of-band management traffic is connected to a NPT-1020 platform via the RJ-45 (MNG) connector located on the front panel of the NPT-1020.

The MNG Ethernet connector is wired as a 10BaseT station port for direct connection through an RJ-45-to-RJ-45 straight cable to a port of a 10BaseT Ethernet hub.

Suitable standard Ethernet station cables are available from many sources. Cables of Category 5 or better must be used. In all cases, the length of the cables must not exceed the maximum recommended for the cable type and hub port in use (up to a few dozen meters).

3.5.5 Timing (Clock) Cables The NPT-1020 platform uses an RJ-45 connector on the front panel that integrates the two timing reference interfaces (2 x T3 and 2 x T4). If it has balanced (120 Ω) G.703 interfaces, a multi twisted-pair cable with an RJ-45 connector (supplied by ECI) is used to connect timing signals from the NPT-1020 to the site timing reference distribution subsystems.

If the site timing reference distribution subsystem has unbalanced (75 Ω) G.703 interfaces, configure an adapter with coaxial cables that provides balanced-to-unbalanced conversion (supplied by ECI).



3.5.6 TOD/1PPS Cable The NPT-1020 platform uses an RJ-45 connector on its front panel, marked TOD/1PPS, which provides timing and synchronization input/output signals, supporting IEEE 1588v2 standard.

If it has balanced (120 Ω) G.703 interfaces, a multi twisted-pair cable with an RJ-45 connector (supplied by ECI) is used to connect timing signals from the NPT-1020 to the site timing reference distribution subsystems.

If the site timing reference distribution subsystem has unbalanced (75 Ω) G.703 interfaces, configure an adapter with coaxial cables that provides balanced-to-unbalanced conversion (supplied by ECI).

3.5.7 Electric Traffic Cables Some electric traffic cables can be prepared on site. The following table lists the type of cables and mating connectors needed for each NPT-1020 traffic interface type.

3.5.8 Optical Fibers Optical fibers can be prepared on site. The following table lists the type of cables and mating connectors needed to prepare cables for each NPT-1020 module.

For each optical interface, ECI supplies patch cords with mating optical connectors already attached to the fiber. Therefore, only the optical termination on the ODF side, which is installation-dependent, must be installed on site.

The optical fibers for connecting to equipment installed in a given rack must enter the rack from the top, be threaded through cable guides running along the rack side rails, and end at the FST. The FST must contain enough fiber length for extracting modules from the NPT-1020 and for replacing fiber in case of damage (splicing repairs).

When routing fibers, make sure to observe the minimum bending radius (35 mm).

3.6 Work and Equipment Safety

NOTE: NPT-1020 equipment is intended for installation in restricted-access areas only.

NPT-1020 platforms contain power sources of varying voltages. Note the following guidelines when installing the platforms:

Before you start:

Ensure the integrity of the grounding connections.

Make sure that sufficient lighting is available.

Do not work on any equipment connected to a voltage source (DC or AC).

Ensure that the maximum working temperature does not exceed 70°C.

Use only insulated tools.

Wear protective clothing as required by the requisite safety regulations.

Do not install or maintain equipment connected to external lines (for example, E1 tributaries) during thunderstorms.

Avoid contact with high-voltage sources when installing platforms, cards, and modules.

Make sure you are familiar with the warning signals and labels on the equipment and strictly observe the procedures needed to avoid the indicated hazards.

3.6.1 Grounding Requirements All the equipment, including NPT-1020 platforms, ancillary units, and equipment from other vendors, must be properly grounded at all times. Good equipment grounding is necessary to protect personnel and equipment, minimize noise, and allow the discharge of accumulated static charges to earth.



3.6.1.1 Rack Grounding Requirements Connect the rack to the site grounding bar with a ground cable according to ETSI recommendations (top/bottom connection).

The rack is supplied with a main copper or brass grounding bolt welded to the rack frame. The grounding stud is identified on the rack by the ground symbol label.

The rack grounding bolt must be connected to the site grounding bar by a 35 mm2 (2 AWG) grounding cable or thicker, as short as possible, complying with UL/ETSI recommendations. The bolt must be free of paint. The cable must be made of copper strands and terminated on both sides with bolt terminals.

NOTE: If necessary, the gauge of the grounding lead can also be reduced to the gauge of the RAP power leads.

The rack mounting rails must be free of paint and provide electrical continuity to the main grounding bolt. The resistance between any rail and the rack main grounding bolt must be less than 0.1 Ω.

Pay particular attention to the area in which the RAP is attached. Remove paint from the rack in this area to ensure efficient electrical contact.

CAUTION: Connect the RAP grounding bolt to the rack grounding bolt with a grounding cable complying with UL/ETSI recommendations. The cable must include bolt terminals on both ends and be securely fastened with a nut and a star washer.

3.6.2 DC Power Supply Requirements The NPT-1020 and EXT-2U platforms require two power sources with a nominal voltage of -48 VDC. Each power source is protected by a UL-listed circuit breaker installed in the RAP. The required circuit breakers are included in the installation parts kit supplied with the equipment, and therefore, their current rating is in accordance with the order.

CAUTION: Disconnect both power sources before service.

ATTENTION: Dèbranchez les deux alimentations avant l'entretien.

The site operator must provide a readily accessible UL-listed disconnect device incorporated in the fixed power wiring of the site. This device limits the maximum delivered current to a safe value.

3.6.4 Laser Safety Requirements This section describes the laser safety requirements.

3.6.4.1 Laser Classification The equipment and components with laser devices described in this manual comply with the International Electrotechnical Commission (IEC) safety standards, including IEC-60825-1 - Safety of Laser Products (AS/NZS 2211.2) and IEC-825 – Safety of Optical Fiber Communication Systems.

With specific regard to the laser, NPT-1020 equipment complies with laser product performance standards set by government agencies for Class 1 laser products. The product and its accessories do not emit hazardous light, and the beam is totally enclosed during all operating modes and maintenance.

LASER WARNING: When the NPT-1020 operates in conjunction with OM_BA or OM_ILA optical amplifiers (installed in the EXT-2U) the NPT-1020's Laser classifications changes to Hazard Class 1M Laser Product.



3.6.4.2 Warning Labels for Laser Products The following labels are affixed to the platform front panel. The labels indicate that the product is classified as a Class 1 Laser Product.

Figure 3-2: Laser warning label

LASER WARNING: The NPT-1020 is classified as a Class 1 Laser Product.

LASER ATTENTION: APPAREIL ’A LASER DE CLASSE 1.

3.6.4.3 Laser Safety Statutory Warning All personnel involved in equipment installation and maintenance must be aware that laser radiation is invisible. Therefore, although protective devices generally prevent direct exposure to the beam, personnel must strictly observe the applicable safety precautions and in particular must avoid staring into optical connectors, either directly or through optical instruments.

3.6.4.4 Laser Device Operating Precautions In addition to the general precautions described in this section, be sure to observe the following warnings when operating a product equipped with a laser device. Failure to observe these warnings could result in fire, bodily injury, and damage to the equipment.



WARNING: To reduce the risk of exposure to hazardous radiation, note the following:

When performing maintenance and other activities on equipment using lasers, it is recommended that you use protection goggles for the wavelength range of 1300 nm to 1600 nm.

Only authorized personnel must carry out hot insertion or swapping of an optical module or optical interface module.

To prevent irremediable damage to your eyes, avoid looking into the fiber when hot-removing and/or inserting a fiber termination.

Place plastic covers on module fiber ports and fiber terminations that are not currently in use.

Do not operate controls, make adjustments, or perform procedures associated with the laser device other than those specified herein.

It is strictly forbidden to interfere with any protective devices and interlocks that are used to prevent direct exposure to the laser beam.

3.7 Protection against Electrostatic Discharge This section provides guidelines regarding the protection of NPT-1020 equipment and its components against electrostatic discharge (ESD) during handling, packing/unpacking, transport, installation, commissioning, inspections, servicing, and maintenance.

Electronic equipment, assemblies, and components that are ESDS (electrostatic discharge sensitive) or include sensitive items are identified by the basic ESD warning symbol shown in the following figure.

Figure 3-3: Basic ESD warning symbol

The information provided in this section is in line with CENELEC Electronic Components Committee (CECC) specification CECC 00 015, which deals with protection of devices sensitive to ESD.

Most types of electronic equipment, assemblies, and components can be damaged by electrostatic discharges. An ESD between two objects occurs when an object carrying static electrical charges touches or is brought near another object.



Static electrical charges appear as a result of friction between surfaces of insulating materials or separation of two such surfaces, and may also be induced by electrical fields. Routine activities such as walking across an insulating floor, friction between garment parts, friction between objects, and so on, can easily build up charges to levels that may cause damage, especially when humidity is low.

In many cases, the build-up of charge can be avoided by using special materials, for example, garments and packaging of antistatic materials or materials that have high resistance, but yet are not insulators.

The best way to avoid damage by ESD is a combination of means and procedures that achieves the following goals:

Avoids build-up of electrostatic charges

Creates a protected work environment that helps prevent ESD

Provides means for controlled discharge of any accumulated electrostatic charges when entering the protected work environment

NOTE: An area in which ESDS can be handled with minimum risk of damage as a result of ESD or fields, and in which the operator is not exposed to additional risks, is called an ESD Protected Area (EPA).

3.7.1 Personnel Training During production and assembly, equipment is handled in workspaces especially prepared and certified to serve as a permanent EPA. However, in many cases, the environment in which the same equipment is installed or maintained cannot be assumed to form an EPA with a permanently controlled boundary. Therefore, all the work involving handling of unprotected ESD must be considered as field work.

Field work in this context includes such activities as service and maintenance, installation, site inspections, and commissioning of components and assemblies classified as ESDS, together with associated packing and unpacking activities.

All the staff involved in field work must be trained to perform their work in the same way as that performed in permanent EPAs with respect to the material quality, personal responsibilities, training, labeling, and packing.

3.7.2 Use of a Temporary EPA Where necessary, use a temporary EPA. The EPA toolkit includes:

Wrist strap with 1 M Ω series resistor

Bonding strap with 1 M Ω series resistor

ESD carpet (work surface), 0.25 m2 minimum

The temporary EPA must include temporary controlled work surfaces and/or flooring capable of providing protection against ESD.



CAUTION: The temporary EPA must be constructed in a way that ensures electrical bonding of all the materials used, and prevents the occurrence of any sudden changes in potential within the EPA that could cause unacceptable voltages or discharges to be applied to ESDS.

The operator and any work surface and flooring must be bonded to ground equipotentially. For this purpose, the work surface and wrist straps must be bonded either to a designated ground bonding point or to the equipment being serviced.

Whenever available, the mains’ ground serves as the ESD grounding facility.

WARNING: While the operator is within the temporary EPA, the minimum value of resistance used for bonding to ground must limit the current to ground, produced by voltages accessible to the operator, to limits specified as safe by the applicable regulations (see, for example, CECC 00 015). The same approach is applicable to the surface resistance and resistance to ground of materials used for temporary work surfaces and flooring.

To enable ESD bonding to ground of equipment racks and any other nonmoveable equipment containing ESD, an ESD ground-bonding facility must be located near such equipment, or the equipment must be fitted with a designated ground-bonding point presenting a resistance to ground not greater than 1 MΩ.

3.7.3 Work Arrangements within a Temporary EPA To ensure that effective ESD protection is indeed achieved, the following arrangements must be observed by persons entering and/or performing field work within a temporary EPA:

All operators working within a temporary EPA must wear, as a minimum, an ESD antistatic protecting garment made of cotton.

If the extent of the temporary work area is such that the operator needs to walk and move within that area, the floor of the area must be capable of providing protection against ESD.

The operator must be bonded to ground at all times when handling ESDS.

If it becomes necessary to remove ESDS equipment and transfer it to a temporary work surface away from the other equipment, the ESDS must be given protective packaging unless equipotential bonding to ground of the operator is maintained.

An ESDS unit must be placed directly into protective packaging when it is removed from equipment. A replacement ESDS must be kept in its protective packaging until required for immediate installation in the equipment.

The field service operator must ensure that the materials and tools necessary to maintain and control the temporary EPA are available at the place of the field work at service time.

All tools for use within the EPA must, as far as is practical, be constructed so that they do not generate or hold an induced electrostatic charge.



3.8 Environmental and Health Concerns ECI is committed to achieving high standards of environmental quality and product safety.

The International Standardization Organization (ISO) has developed the internationally recognized standards ISO 9001 and ISO 14001. These are quality management standards that are administered by independent accreditation and certification bodies.

ISO 9000 is a family of standards for quality management systems that has been accepted as a model when assessing the adequacy of quality management systems. Some of the requirements in ISO 9001 (one of the standards in the ISO 9000 family) include:

Procedures that cover all key business processes

Process monitoring to ensure effectiveness

Adequate record-keeping

Monitoring output for defects, with appropriate and corrective action where necessary

Regular review of individual processes and the complete quality system as a whole

Facilitating continual improvement

ISO 14000 is the international specification for an Environmental Management System (EMS). It specifies requirements for establishing an environmental policy, determining environmental aspects and impacts of products, activities, and services, planning environmental objectives and measurable targets, implementation and operation of programs to meet objectives and targets, checking and corrective action, and management review. ECI Quality and Environmental Management Systems were certified to these ISO standards and are periodically audited by third-party organizations.

As a part of ECI’s environmental commitment and in pursuit of compliance with applicable environmental legislation, ECI makes every effort to ensure that its products supplied to the EU market are compliant with the RoHS Europe directive restricting use of certain hazardous substances in electrical and electronic equipment. ECI also requires RoHS compliance from all its suppliers. All new electrical and electronic equipment delivered to locations within the EU do not contain any cadmium (Cd), lead (Pb), hexavalent chromium compounds (Cr6+), mercury (Hg), polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), subject to certain exemptions and limitations as outlined in the RoHS directive.

Without limiting the generality of the preceding statement, we wish to stress that use of lead in solders in network infrastructure equipment has been exempted by the RoHS directive and may be found in certain ECI products.

All equipment delivered to locations within the EU complies with the requirements of the RoHS Europe directive. Similarly, ECI equipment is compliant with the RoHS California directive and RoHS Chinese directive where relevant. All ECI equipment included in the Electronic Information Products (EIP) category includes a table of Toxic and Hazardous Substances and Elements, verifying hazardous substance levels in accordance with the RoHS China directive. Equipment documentation includes the appropriate Environmental Protection Use Period (EPUP) lifespan symbol indicating the point in time when the equipment may be expected to enter the recycling system. The following are examples of these pollution control symbols.



Figure 3-4: Pollution control logos

NOTE: The number in Logo 2 is for illustrative purposes only. When in actual use, the number indicates the corresponding environmental protection use period of the product.

ECI adheres to the Waste Electrical and Electronic equipment (WEEE) directive requiring that all new products introduced into the EU market be labeled with the crossed-out wheeled bin recycling symbol defined by CENELEC standard EN 50419 and accepted by the member states. Note that specific WEEE procedures may differ from state to state, depending on the local implementation of the WEEE requirements.

Before you start:

Before unpacking, make a preliminary inspection of the shipping boxes. Immediately report evidence of damage to the carrier, the project manager, and your local ECI representative.



CAUTION: Static Sensitive Devices

Proper handling and grounding precautions required

NPT-1020 equipment contains components sensitive to ESD. To prevent ESD damage, strictly observe all the precautions listed in Protection Against Electronic Discharge. Keep parts and cards in their antistatic packaging material until you are ready to install them.

The use of an antistatic wrist strap connected to a grounded equipment frame or rack is recommended when handling cards and modules during installation, removal, or connection to internal connectors.

To unpack the equipment:

1. Place the shipping boxes with the top upwards on a clean flat surface. Cut the sealing tape using a short knife so as not to damage the internal items, and open the top flaps.

2. Remove the items contained in the box and inspect each one for damage. Check for loose parts or any visual damage to the rack, platform, and auxiliary equipment. Also check the integrity of all the connectors, leads, and cables.

NOTE: Do not remove plastic covers from optical connectors until optical cables are connected to them.

3. Search the shipping boxes for any additional small items that may be present.

4. Open each of the module and card packages for inspection, but do not remove the modules/cards from their individual protective packages until they can be inserted in the platform.

5. Check the contents of the shipping boxes against the packing list attached to each box. If damaged parts are detected or if any parts are missing, notify the project manager and your local ECI representative immediately.

4.5 Installation Options It is recommended that NPT-1020 platforms be installed in ECI approved racks. These racks can be installed on wooden, concrete, or suspended floors, or suspended from overhead mountings.

The following racks are supported:

5.10 Routing and Connecting Cables and Fibers in the Cabinet

In general, all electrical traffic cables, power cables, alarm cables, and data cables must be routed in the space beneath the NPT-1020 platform and the cabinet floor. All optical fibers are routed through the flexible tube attached to the right side of the cabinet. The side to which the cables are passed is determined by the side of the connectors on the NPT-1020 front panel. For instance, power connectors are on the left side of the NPT-1020, so the power cables are routed on the left side beneath the platform. The cables are then attached to the cable guide on the left side of the cabinet with cable ties.

When routing the various types of cables, several principles must be observed to avoid electromagnetic and RF interference:

Traffic cables must not be routed in the same route as power cables.

Optical fibers must always be routed through the special flexible tube only.



The following sections provide detailed descriptions of cable and fiber connection and routing.

5.11 Connecting Fibers and Cables to the NPT-1020 in Wall-Mounted Cabinet

In general, all electrical traffic cables, power cables, alarm cables, and data cables should be routed along the sides of the wall-mounted cabinet. All optical fibers must be routed through the fiber guide tube. Electrical traffic and other cables (DC, alarm, management, timing, and so on) must be routed along the side of the cabinet, and held in place with cable ties.

Use detailed practices described in the NPT-1020 Installation Manual for performing the cables routing and connections.



In general the electrical traffic cables should not be routed in the same route as power cables. The power connectors on the NPT-1020 are on the left; therefore they should be routed from the left side of the NPT-1020 pass in the space between the NPT-1020 and the unit installed above it. Then the cable should be passed through the left cable guide, routed up to the left cable clamp bar and attached to it with cable ties. It should then be passed upward to the openings in the top cover of the cabinet to the outer world.

In a similar way, cable connected to connector on the right side of the NPT-1020, for instance T3/T4 (clock) cable should be routed from the right side of the NPT-1020 in the space between the unit and the unit installed above it. Then the cable should be passed through the right cable guide, routed up to the right cable clamp bar and attached to it with cable ties.

The route of fibers connected to the NPT-1020 should always pass through the fiber protection tube. This means that the fiber should be inserted in the tube and come out from its other side from there it should be routed upward to the opening in the top cover of the cabinet.

5.12 Installing the Wall-Mounted Cabinet Covers and Door

3. Attach the grounding cable with the nut and spring washer removed in Step 1, and fasten the cable to the bolt.



5.18 Routing and Connecting Cables and Fibers in the Frame

In general, all electrical traffic cables, power cables, alarm cables, and data cables are routed in the space beneath the NPT-1020 platform and the frame floor. All optical fibers should be routed through the flexible tube attached to the right side of the wall-mounted frame. The side to which the cables are passed is determined by the side of the connectors on the NPT-1020 front panel. For instance, power connectors are on the left side of the NPT-1020, so power cables are routed on the left side beneath the platform. The cables are then attached to the cable supports on the left side of the frame with cable ties.

When routing the various types of cables, observe these principles to avoid electromagnetic and RF interference:

Traffic cables must not be routed in the same route as power cables.

Optical fibers must be routed through the special flexible tube only.

19 Check there are no abnormal alarms.

6.2.3 Measuring Optical Levels These measurements check optical signal levels at the various equipment ports. Before performing any other commissioning test, proper optical levels within the limits specified in the NPT Product Line System Specifications must be achieved for each optical component.

Perform these measurements using an OPM configured according to the wavelength at the measurement port. For reliable measurement, do not connect the OPM directly to a port but use a two-meter fiber. When measuring high optical power levels, use attenuators to ensure that the power does not exceed the maximum OPM input level.

The following table illustrates a typical data form for optical level measurements.

Table 6-3: Measured optical levels

Slot Module type Port Wavelength Optical transmit level (dBm)

Receive level (dBm)



The measured power levels:

Must be within the range of minimum and maximum levels specified in the NPT Product Line General Description for the transceiver plug-in type installed on the corresponding port.

Must be within the expected range according to the optical network plan.

It is usually sufficient to measure the optical levels at the receive ports only. A good port-receive level indicates that the components in the optical path up to that port are properly connected and operating normally. If the result is not satisfactory, perform additional measurements at the transmit port in the remote site.

6.2.4 Platform Power-On Test Procedure

To power on the NE:

1. Perform slot assignments for all the relevant cards and modules in the platform.

2. After 10 seconds, turn the platform circuit breaker off.

3. After 30 seconds, turn the platform circuit breaker on.

The equipment should automatically return to normal operation, without user intervention and without any abnormal alarms in the system.

6.3.2 Network Timing Synchronization Test This test checks that the NPT-1020 NEs synchronize properly and switch to the next priority clock source when a failure occurs.

To perform network timing synchronization test:

1. Define one NE as the (internal) timing source to which all other NEs are synchronized. This test can be done with an external timing source, if requested.

2. Define several priorities for the timing source.

3. Disconnect the Rx fiber connected to the NE defined as the main timing source.

If the NE has two or more timing sources, it synchronizes to the second priority source, and an alarm is generated for the missing main timing source.

If the NE has only one timing source, the NE timing is set as “hold-over” and an alarm is generated for the main timing source. Another alarm is generated to indicate that there is no available timing source.



6.3.3 Loss of Signal (LOS) Detection Test This test verifies that NEs recognize alarms and send an alarm notification to the management system for viewing.

To perform a LOS detection test:

1. Create NEs and links through the management system.

2. Disconnect the Rx optical fiber from one of the modules. A LOS alarm at the SPI level of this module port appears, together with other alarms generated by the disconnection.

6.3.4 Input Sensitivity Test This test verifies that the input sensitivity of the NPT-1020 optical modules is according to specifications.

To perform an input sensitivity test:

1. Create one unprotected trail of any rate between two NEs.

2. Connect test equipment to one NE and perform a loopback at the other NE (in the relevant endpoint ports).

3. Connect a variable optical attenuator to one of the fibers of the relevant trail, and set the attenuator to 0 dB.

4. Increase the attenuation gradually until the test equipment displays a burst of errors.

5. Connect an OPM to the first Rx point after the variable optical attenuator and measure the total power. The measured optical power level is the input sensitivity of the module.

6. Verify that the results are in accordance with the NPT Product Line System Specifications.

6.3.5 Equipment Power-On Test This test verifies that the NPT-1020 NEs continue operating properly after a power break, without operator involvement.

To perform an equipment power-on test:



3. Shut off the power to one of the nongateway NEs within the relevant trail. Errors and an Alarm Indication Signal (AIS) alarm appear in the test equipment. After approximately seven minutes, an “NE disconnected” alarm appears in the management system current alarm list, and the NE icon turns gray (indicates no communication).



4. Power on the NE and wait for it to perform the initial download to all cards/modules in the platform. This can take five minutes.

5. Verify that the NE is connected to the management station and that there are no relevant alarms in the test equipment or at the management station.

6.3.6 Traffic Stability Test This test verifies that traffic operates according to ITU-T standards.

To perform traffic stability test:



3. Run this test for the appropriate time interval according to the following table.

4. Verify that no alarms appear in the test equipment or at the management station. You should achieve an error-free rate of 1 x 10-11 for 2 Mbps and 1 x 10-12 for all other rates.

Table 6-8: Traffic stability test time intervals

2 Mbps 34/45 Mbps STM-1/VC-3 STM-4/VC-12

14 hours 7 hours 120 minutes 30 minutes

6.3.7 Path Protection and Nonretrieval Test This test verifies that SNCP traffic operates properly when a failure occurs.

To perform a path protection and nonretrieval test:

1. Create one protected trail of any rate between two NEs.


3. Disconnect one of the fibers in the active path of the trail. Short alarm bursts of less than 50 msec appear in the test equipment, and the management station reports an alarm in the active path of the trail.

4. Verify that the trail works properly on the protection path.

5. Reconnect the optical fiber. The trail remains on the protection path (nonretrieve mode), and there is no alarm in the test equipment.



6.3.8 Severity Assignment Test This test, which is performed on one NPT-1020 NE, determines the level of urgency accorded to each alarm and creates an alarm-handling protocol.

When a fault is detected or removed, the NE updates the status of the LEDs and reports the alarm activation or clearing to the management station.

To perform a severity assignment test:

1. Disconnect a fiber from one of the optical interfaces. An SPI LOS alarm of critical severity appears on the management station for the NPT-1020 and the MJR LED on the NPT-1020 panel turns on.

2. Reconnect the fiber. The SPI LOS alarm on the management station clears and the MJR LED on the NPT-1020 panel turns off (only if there are no other alarms on the NPT-1020 unit).

3. Change the severity of the SPI LOS alarm to minor.

4. Disconnect a fiber from one of the optical interfaces. An SPI LOS alarm of minor severity appears on the management station for the NPT-1020 and the MNR LED on the NPT-1020 panel turns on (only if there is no critical or major alarm on the NPT-1020 unit).

5. Reconnect the fiber. The SPI LOS alarm on the management station clears and the MNR LED on the NPT-1020 panel turns off (only if there is no other alarm on the NPT-1020 unit).

6.3.9 Transmission Alarm-Handling Test This test verifies that the NPT-1020 NEs can recognize an alarm and send an alarm notification to the management system, and that the management system displays it properly.

This procedure tests the following alarms: PDH-LOS, PDH-AIS, and SPI-LOS.

To perform a transmission alarm-handling test:


2. Connect PDH test equipment to one NE and perform a loopback at the other NE (in the relevant endpoint ports).

3. Disconnect the Tx cable of the test equipment. The management station reports a LOS alarm for the relevant PDH port.

4. Set the test equipment to transmit an AIS (AIS = on). The management station reports an AIS alarm for the relevant PDH port.

5. Disconnect the Rx fiber of an optical port. The management station reports a LOS (SPI-LOS) alarm for the relevant optical port. If ALS = off, the management station reports a far-end optical port MS-RDI alarm.

If ALS = on, the management station reports a far-end optical port LOS alarm.



6.3.10 Maintenance Action Test This test verifies that maintenance actions can be performed in the NPT-1020 NEs using the management system.

This procedure tests a near-end loopback, forced PDH AIS, forced low-rate RDI, forced high-rate RDI, and forced MS-RDI.

To perform maintenance action test:


2. Connect test equipment to one NE. The PDH test equipment detects an AIS alarm.

3. Perform a near-end loopback at the other trail endpoint. The AIS alarm in the PDH test equipment clears, and no alarm or error remains on the PDH test equipment.

4. Using the management station, execute forced AIS on the PDH port that connects to the test equipment. The PDH test equipment detects an AIS alarm.

5. Using the management station, execute a forced low-rate RDI (or forced high-rate RDI or forced MS-RDI) on a NPT-1020 platform. Another NPT-1020 platform reports a low-rate RDI (or high-rate RDI or MS-RDI) to the management station.

6.4 Data Network Commissioning Tests The data network commissioning tests check that data functionality is in accordance with system specifications.

6.4.1 Throughput and Latency Tests These tests determine the time it takes to transmit frames through the network, and the maximum amount of data that can pass through the network before frames are lost.

To perform throughput and latency tests:

1. Create two unprotected Ethernet trails of any rate between two NEs in the network.

2. Connect test equipment to both ports of one NE and connect two ports of the other NE through an Ethernet cable.

3. Configure the test equipment for RFC-2544 throughput and latency measurement.

4. Measure the throughput and latency for frame sizes 64, 128, 256, 512, 1024, 1280, and 1518 bytes, and record the results in the appropriate table.



NOTE:

Measured latency is for both the forward and return paths. For a single path, the latency is 50% of the measured value.

The latency test is dependent on the throughput results. For example, if 10 Mbps is tested and the throughput is 4%, the latency test should be for 4 Mbps (2 * VC-12 = 4 Mbps).

Inject traffic according to the assigned bandwidth (VC-12 = 2.048 Mbps).

6.4.2 System Recovery and Reset Tests These tests determine the speed at which a device recovers from a buffer overflow condition or from a power failure.

To perform system recovery and reset tests:

1. Create two unprotected Ethernet trails of any rate (for example, 10/100 Mbps) between two NEs.

2. Connect test equipment to both ports of one NE and connect two ports of the other NE (in the relevant endpoint ports) through an Ethernet cable.

3. Configure the test equipment for manual testing according to the port rate and for any frame size.

4. Power off one of the NEs and verify packet loss in the test equipment.

5. Turn on the NE, wait five minutes, and verify that the errors in the test equipment have cleared.

6.4.3 Frame Loss Rate Test This test determines the number of frames that are lost when the system is overloaded.

To perform a frame loss rate test:

1. Create two unprotected Ethernet trails between two NEs.


3. Configure the test equipment for RFC-2544 for frame loss measurements. Set to 100%. The frame loss rate in % is defined according to the following formula:



[(input fps) - (output fps)] * 100 / (input fps) fps = frames per second

For example, for a 100 Mbps test using 5 * VC-12 = 10 Mbps, with input fps = 148810 and output fps = 14881, the frame loss is:

148810 - 14881 = 133929 (a 90% loss).

Frame rate (% MFR) 100%

6.4.4 Stability Test This test determines the stability of the network by checking that it can function with no errors for a defined period of time.

To perform a stability test:

1. Create two unprotected Ethernet trails of any rate (for example, 10/100 Mbps) between two NEs.


3. Configure the test equipment for manual testing according to the port rate and for any frame size.

4. Set the transmit rate in the test equipment to about 90% of the trail bandwidth.

5. Run this test for two hours, and verify that no errors appear in the test equipment.

6.4.5 Alarm-Handling Test This test checks the alarm conditions forced on the NE and the subsequent action carried out by the NE. It tests signal loss to both the data LAN port and to the optical interfaces.

To perform an alarm-handling test:

1. Create two Ethernet trails of any rate (for example, 10/100 Mbps) between two NEs.


3. Disconnect the test equipment to create a signal loss to the data LAN port. This generates a 10/100 Mbps - Link Down alarm.

7.4 Onsite Troubleshooting The purpose of onsite troubleshooting is to identify the hardware causing the malfunction and return the equipment to normal operation as soon as possible.

Troubleshooting is usually initiated in response to one of the following conditions:

Alarm or performance degradation reported by the management station.

Alarm or malfunction detected onsite by maintenance personnel, either as a result of a troubleshooting activity initiated by the management center personnel or as a result of a periodic inspection or preventive maintenance action. Many problems can be detected via the various indicators available on the NPT-1020 system components.

This chapter assumes familiarity with the NPT-1020, with SDH data, and with the LightSoft and EMS-APT management stations. See the respective user manual for details on the various capabilities of the management stations and for instructions on performing the necessary activities.

The following sections provide procedures for performing onsite troubleshooting for various trouble categories. For each category, a troubleshooting table provides instructions for identifying the problem.



To use the troubleshooting table:

1. Identify the closest description of the trouble symptoms under “Symptoms”.

2. Perform the required corrective actions listed under “Corrective actions” in the order they appear, until the trouble is corrected.

1 Green transceiver Laser On indicator off

SFP module damage On the LCT-APT, if the SFP type cannot be successfully obtained, the IDPROM of the SFP module may be damaged. Replace the module.

If the SFP type information is consistent with the expected SFP type, force the laser on through the LCT-APT. The laser on indicator should be on. If not, the SFP module or the optical module is damaged. Replace the damaged module.

Incorrect configuration On the LCT-APT, check whether there is an SFP-type-mismatch alarm in the corresponding optical interface.

If yes, check the expected SFP type first. Correct it if it is not correct.

Then, check the SFP module type. If it is not the same as the expected SFP type, replace the SFP module with the proper type.



No. Symptom Probable cause Corrective actions

Corresponding optical transmitter may have been turned off by the ALS function (see the following note)

Check that all the fibers are properly connected to the corresponding optical transceiver.

When available, select Maintenance > Laser Management > Laser Switch > Force Laser On in the LCT-APT to activate the corresponding laser.

Use an OPM to measure the output optical power. If the output optical power is not within the range of minimum and maximum levels specified in the NPT-1020 System Specifications during a 90-second period, the problem is in the transmit side of the transceiver. Remove and reinsert the transceiver.

Check the output optical power again. If the output optical power is still not within the range of minimum and maximum levels specified in the NPT-1020 System Specifications, replace the transceiver.

If the problem persists, check the received optical power with an OPM. If the optical power is within the range of minimum and maximum levels specified in the NPT-1020 System Specifications, replace the transceiver.

If the problem persists after following the previous steps, check the remote site.

If there are no problems on both sites, the problem may be in the optical fiber between the two sites.

NOTE: Be sure to turn on the ALS function after performing all checks.

NOTE: An optical port with ALS capability turns off its transmitter when the corresponding receive signal is lost. Turning the transmitter off may cause a chain reaction, which turns the optical signals off in a whole section of the network and generates a large number of alarms. As a result, it may be difficult to identify the real cause of the problem, and you may need to use the management station log records to identify the port.

7.5 Replacing Cards and Modules The following sections provide procedures for replacing cards and modules in the NPT-1020.

7.5.1 Safety and Workmanship Refer to Before You Start for safety and workmanship instructions.

CAUTION: Static Sensitive Devices

PROPER HANDLING AND GROUNDING PRECAUTIONS REQUIRED

NPT-1020 equipment contains components sensitive to ESD. To prevent ESD damage, strictly observe all the precautions listed in Protection Against ESD. Keep parts and cards in their antistatic packaging material until you are ready to install them.

Use an antistatic wrist strap connected to a grounded equipment frame or rack when handling cards and modules during installation, removal, or connection to internal connectors.

Before you start:

When inserting cards and modules, be sure to carefully align the card/module with the platform guide rails. If you feel resistance during insertion, immediately retract the card/module and repeat the process.

Hold the card/module straight during insertion and removal, and pull or push it slowly and carefully to avoid touching components located on adjacent cards/modules.

Do not use excessive torque when tightening the fastening screws of cards and modules.

Visually inspect the card and the mating backplane connectors and make sure that there are no signs of physical damage. In particular, check for bent connector pins.



Before replacing any card, module, or optical transceiver:

1. Check that the replacement component has not been physically damaged during shipment.

2. Remove the replacement component from its antistatic protection packaging, and perform a visual inspection to detect damage during shipment. Report any problems.

3. Record the hardware and software versions as indicated on the component identification labels, and make sure they are compatible with those of the component to be replaced.

After replacing a component:0.

1. Place it in its antistatic protection packaging and close it.

2. Attach a report to the packaging explaining the reason for the replacement, and identify the network site, physical location, platform, and time of replacement.

7.5.2 Replacing Tslot Cards

To replace a Tslot card in the NPT-1020 platform:

1. Mark each cable connected to the Tslot card for identification purposes.

2. Disconnect all cables connecting the Tslot card.

3. Loosen and remove the two screws.

4. Hold the handle on the Tslot card panel and pull the card to be replaced outward until it is released from the backplane.

5. Continue to hold the handles and gently pull the card out of the platform.

6. Insert the rear end of the replacement card into the corresponding card guides.

7. Push the replacement card in until the front panel of the card is flush with the front of the NPT-1020 platform. If resistance is felt before the connectors are flush, pull the card out and repeat the procedure.

8. Close the screws on the panel to fasten the card to the NPT-1020 platform.

9. Reconnect all cables for the Tslot card according to the cable marks.



7.5.3 Replacing Eslot Cards

NOTE: All Eslot cards support live insertion. There is no need to power-off the NPT-1020 or the EXT-2U units when replacing them.

To replace an Eslot card in the EXT-2U platform:

1. Mark each cable connected to the Eslot card for identification purposes.

2. Disconnect all cables connecting the Eslot card.

To replace the power module:

1. Cut off the power source connected to the power module by turning off the corresponding power switch on the RAP.

2. Disconnect the power cable from the replaced power module on the panel.

3. Open the two screws fastening the power module to the platform.

4. Hold the handle on the panel and pull the module to be replaced outward until it is released from the backplane.

5. Continue to hold the handles and gently pull the module out of the platform.


7. Push the replacement module in until the front panel of the module is flush with the front of the NPT-1020 or EXT-2U platform. If resistance is felt before the connectors are flush, pull the module out and repeat the procedure.

8. Close the screws on the panel to fasten the module to the NPT-1020 or EXT-2U platform.

9. Reconnect the power cable to the replacement power module.

10. Turn on the power switch on the RAP.



7.5.7 Replacing SFP/CSFP/SFP+ Transceivers ECI supplies field-replaceable SFP/CSFP/SFP+ transceivers in all optical and electrical STM-1 interfaces. Hot swapping is allowed, provided you observe the safety precautions described in Before You Start during the replacement.

To replace an SFP/CSFP/SFP+ transceiver:

1. Mark each fiber or cable connected to the transceiver for identification purposes.

2. Identify the position of the SFP/CSFP/SFP+ transceiver to be replaced.

3. Disconnect the fibers or cables connected to the transceiver.

4. Remove the transceiver plug-in by pulling its tab.

5. Insert the rear end of the replacement transceiver plug-in into the prescribed position, and push slowly backward to mate its rear connector with the corresponding optical interface module connector until the transceiver clicks into place (see the following figure). If you feel resistance before the transceiver plug-in is fully inserted, retract the transceiver and repeat the process.

Figure 7-1: Inserting an SFP/CSFP/SFP+ transceiver into a module

6. Reconnect the fibers or cables disconnected in Step 3.

8.19.2 ALARM IN/OUT Connector The ALARM IN/OUT connector is a 68-pin SCSI female connector that carries three groups of lines to the customer equipment:

Sixteen external alarm inputs connected to the ALARM inputs of the NPT platforms. Four inputs are allocated to each one. Each input is activated by closing a dry contact provided from the customer's facility.

Eight sets of changeover relay contacts, floating with respect to platform ground, that serve as rack (bay) status outputs. Each couple of the eight relays is assigned to the two output alarm lines of each NPT platform connected to the RAP-4B.

Four sets of changeover relay contacts, floating with respect to platform ground, that serve as rack (bay) alarm indication lines. The relays, identified as critical, major, minor, and warning, are activated by the corresponding alarm relays of NPT platforms.

Relay contact ratings are 72 V in open state and 1A in closed state.



The following figure identifies the ALARM IN/OUT connector pins, as seen when looking into the connector.

9 Rack Installation

9.1 Installing Equipment Racks

NOTE: The instructions in this Appendix are relevant to the installation of all rack types. However, it is recommended that NPT-1020 platforms be installed in ETSI A racks.

9.1.1 Marking Rack Floor You need to mark out the rack floor plan before installing the rack.

Before you start:

Before starting, find the prescribed location of each equipment rack.

If you have not yet unpacked the rack and the associated mounting kits, do so now (see Unpacking and Performing Visual Inspection).

To mark out the rack floor plan:

1. For each rack, mark out the floor at the rack location(s) according to the floor plan template corresponding to the type of rack being installed:

ETSI A and ETSI B racks: Use template of diagram a. in the figure "Mounting diagrams for ETSI racks" (Rack Installation on Wooden Floors).

23” rack: Use template of diagram a. in the figure "Mounting diagrams for 19” and 23” racks" (Rack Installation on Wooden Floors).

19” rack: Use template of diagram b. in the figure "Mounting diagrams for 19” and 23” racks" (Rack Installation on Wooden Floors).

The marked locations are a helpful guide for positioning the racks.

2. If the installation is located at a site with a floating (suspended) floor, also mark out all cable entry slots.

3. For concrete or wooden floors, mark out all the points designated for equipment bolting.

NPT-1020 Installation and Maintenance Manual Rack Installation


9.1.2 Installing the Rack on Concrete Floors

To install the rack on a concrete floor:

1. Drill the required mounting holes in accordance with the appropriate template. See diagram a. in the figure "Mounting diagrams for ETSI racks", and diagram a. or b. in the figure "Mounting diagrams for 19” and 23” racks" (Rack Installation on Wooden Floors).

2. Insert expansion shields into the holes.

3. Position the rack over the mounting holes.

4. Secure the rack to the floor with the bolts supplied in the mounting kit, in accordance with diagram b. or diagram c. in the figure "Mounting diagrams for 19” and 23” racks" (Rack Installation on Wooden Floors).

9.1.3 Installing the Rack on Wooden Floors

To install the rack on a wooden floor:

1. Drill the required mounting holes in accordance with the appropriate template (see the following figures), using a 5 mm drill bit.


3. Secure the rack to the floor using the appropriate wood screws (see the following figures).



Figure 9-1: Mounting diagrams for ETSI racks



Figure 9-2: Mounting diagrams for 19" and 23" racks

9.1.4 Installing the Rack on Floating (Suspended) Floors

To install the rack on a floating (suspended) floor:

1. Drill the required mounting holes in the suspended floor, in accordance with the appropriate template.


3. Secure the rack to the floor in accordance with diagram c. in the figure "Mounting diagrams for ETSI racks" (Rack Installation on Wooden Floors).



9.1.5 Installing the Rack on Suspended Overhead Trays

To install the rack on a suspended overhead tray:

1. See the following figure and position the overhead rack securing brackets.

2. Secure the rack to the overhead cabling trays, using the adjustable brackets. 2200 mm high racks may also be attached to the ceiling; 2600 mm racks are generally attached only to the ceiling.

Figure 9-3: Rack mounting diagram for attachment to suspended overhead tray (2200 mm rack)

9.1.6 Installing Extendable Rails In high-density installations, it may be necessary to install the xRAP above the rack using the extendable installation rails available from ECI.

In this case, attach the extendable installation rails to the top of the rack before installing the equipment.

9.1.7 Grounding the Rack Immediately after installing the rack, connect its grounding stud to the prescribed grounding point on the site grounding bar.

Use a grounding lead that meets the requirements described in Rack Grounding Requirements.



9.2 Installing 19" Racks The NPT-1020 can also be installed in European 19” racks. This is accepted under the limitations that the rack’s general dimensions are according to the following figure. Any other European 19” rack must first be examined and approved by ECI.
