1.6 Safety Instructions

Persons other than the maintenance personnel must not touch the devices inside theAC-Distribution. The AC-Distribution involves a high voltage and high current. Touchingit can lead to an electrical shock or accident.

Make sure not to touch parts of the Node B that contains components with high voltageor current. An inadvertent contact with any of these components can cause injury, death,and/or damage to the system.

Be sure to provide grounding where required. A failure to do so can lead to a systemfailure or electrical shock at the time of lightning.

When measuring voltage or current, take adequate insulating measures, such ascovering or winding the superfluous parts of the measuring terminal and tools with insu-lating tape. Allowing the measuring terminal to touch another terminal or a short-circuitcaused by a tool can lead to an electrical shock or accident.

Before making a connection with the DC-PDB, ensure that the power to the main andbattery circuit breaker is OFF. Making a connection with the DC-PDB when the poweris ON can lead to an electrical shock or accident.

Before making a cable connection, be sure to turn the switch on the power distributionboard to OFF. Otherwise, an electrical shock or accident can result.

Before making a cable connection, confirm the electric polarity. If the cable is connectedwith wrong polarity, an electrical shock or accident can result.

Make sure to follow the additional safety instructions in this manual.

i NOTEThe NodeB is called NB-440 if the rack is equipped with LPA, TRX and REP modules.The configuration can be updated with DRIC and CAT modules. In this case a fullyNB-880 functionality is provided. Because a re-labelling is not foreseen, the NodeB willcalled in future also NB-440.The NodeB racks delivered from the factory with DRIC /CAT modules will be called NB-880 and a lable with this number is fixed at the rack front.



The NB-440/NB-880 rack contains the following modules:

Core Controller (CC):

The Core Controller is consist of 4 boards: CPU board, ATM board, LIU board and theSTM-1 board.

Channel Coding Card (CHC):

The main function of CHC is the decoding in uplink direction.

Duplexer Amplifier Multi Coupler (DUAMCOF):

A duplexer combines the transmit and receive paths to the common antenna connector.The receive and transmit part of the duplex filter, respectively, provide a substantial partof the transmit and receive band filtering that is required.

Over Voltage Protection and Tracer (OVPT):

Protects the E1 and J1/T1 ports of the Iub interface and the external synchronizationclock input of the Node B from overvoltage and provides interfaces for connection of ex-ternal monitoring equipment without interruption.

The following modules are installed in the NB-440 rack only:

Repeater Card (REP):

The REP card provides a multiplexing function for base band signals. The card sorts thedownlink signals from the CHC cards according to antennas and sends them to the TRXcards. The card also sends the signals from the TRX cards to the CHC cards in uplinkdirection.

Transceiver Card (TRX):

The TRX card features a transceiver base band block (TRX BB) and a radio frequencyblock (RF). The radio frequency block is composed of the transmitter block (TX) and thereceiver block (RX). Both TX and RX have diversity configuration. The transmitter blockconverts baseband signals into RF signals and the receiver block converts RF signalsinto base band signals.

Linear Power Amplifier (LPA):

The LPA is the RF power amplifier. A LPA is capable of supporting one or two carriers.

These modules only used in the NB-880 rack and in the upgrated NB-440:

Digital Radio Interface Card (DRIC):

This card combines the functionality of the REP card (see above) and the spreadingfunctionality of several TRX cards. The DRIC provides 6 digital radio interface for up to6 CAT modules. Optionally, a second DRIC can be installed for redundancy reasons.

Combined Amplifier and Transceiver Module (CAT):

On the downlink path, it receives the digital baseband signal from the DRIC card. TheCAT performs channel filtering and upconverts this signal to the required transmittingfrequency. On the uplink path, the CAT module receives RF signals from the DUAMCO,downconverts the signals and transmits the resulting data stream to the DRIC card.

Tower Mounted Amplifier (TMAF):

The TMAF is an (optional) RF unit (external to the Node B rack) which provides themeans to feed the overall Node B downlink signal to one TX/RX antenna and to amplify,with low noise figure, the overall Node B uplink signal coming from the sameTX/RX antenna.

InstallationNode B

IMN:NB-440/NB-880


The numbers of installed modules (excepted CC) are subject to modification; it dependson the number of TRXs and the cell configuration on site.

NB-440/NB-880 is fed by an external -48 V DC source.

The required link equipment for the fixed link to the fixed public telephone network (canbe microwave or NTPM) must find place in a separate shelf on site. Type and layout ofthe shelf depends on customer requirements.

For further information about the hardware architecture refer to the “Technical Descrip-tion UTRAN NB-440/441 and .Technical Description UTRAN NB-880/881

i NOTEAll empty slots in a partially equipped shelf have to be closed with adequate cover parts,so that the air flow inside the rack will not be affected.The cover parts are available with the dimensions 295 x 20 mm (11.6” x 0.8”), 395 x 40mm (15.55” x 1.6”) and 395 x 60 mm (15.55” x 2.4”); (H x W).



2.4.1 Rack Layout NB-440The rack allows a minimal configuration with 1 TRX and can be equipped with up to 6TRX for different cell configurations.

Fig. 2.3 Fully equipped NB-440 rack

2.4.2 Rack Layout NB-880 and upgrated NB-440The NB-440 can be upgrated to provide the fully NB-880 functionality.

In this case, the REP cards, the TRX cards and the LPA modules have to be removedfirst. This is possible after the disconnection of the system cabling at the front of themodules.

After that the DRIC cards and the CAT modules have to be fitted in the matching slotsof the A-and B-shelf.

At least the modified system cabling has to be re-connected and all unused slots mustclosed with cover plates.

– After that, all other cables like DC mains, RF cabling or alarm wires can be installed.– The screen of the RF jumpers has to be grounded before entering the rack via the

cable feeding module, see Fig. 2.50.– If cables are fed through coaxial cable access located at the top of the rack at the

front, the screen has to be grounded like all other coaxial cables.

i NOTEFor later shifting of the NodeB in case of rack extension or to perform maintenanceworks, it can be advantageous to provide an extra length of all external cables.The additional length of the cables (L+, L-, Ground, Iub and external alarms) should bebetween 0,5 m and 1.0 m and can be stored as a loop behind the rack.The alternative solution is the disconnection of all cables.



2.6.2 Ground and Power Supply Connections -48 V DCThe NB-440/NB-880 rack has to be connected to the site specific ground system beforestarting the connection of DC mains cable.

An external ground wire (minimum cross section 16 mm2 (AWG 6), copper conductor)has to be connected on the left or right side ground stud of the rack and must beattached to the ground bar on site.

Connect the NB-440/NB-880 rack and ground system as follows:

1. Use the nearest ground bar on site.2. Ascertain the distances between the connection points of the ground system and the

ground bolt of the rack.3. Cut the cables to the required length.4. Remove the cable insulation at the end to connect to the ground bolt (length approx.

10 mm (0.4”)) and fix a cable lug M8.5. Connect the prepared cable end to the ground bolt.6. Tighten the nut firmly.

Fig. 2.24 Ground and DC mains connections of the NB-440/NB-880

The figure above shows the recommended cabling for the power supply and groundconnections. The recommended cable cross-sections as shown in the figure aboveguarantees the proper function of the NB-440/NB-880, equipped with up to 6 TRX.

The NB-440/NB-880 will be powered by a -48V DC source. The 2-pole terminal block ofthe MSU, located in the top of rack, is the connection point for the DC supply wires.

An easily accessible disconnect device is incorporated into the DC supply wiring. To iso-late the DC mains supply, a 125 A circuit breaker (medium response time and a contactseparation of at least 3 mm) must be installed in the DC distribution box for interruptionof the -48 V conductor. If there no DC pole is grounded, a two-pole disconnect device isnecessary.

To connect the NB-440/NB-880 with the DC mains supply equipment point, proceedwith the following steps:

1. Refer to the site documentation for the required information about type and locationof the DC distribution.

2. Measure the actual distance between terminal block of the MSU and DC distribution.

3. Cut the power supply wires to the required length.4. Cut back the wire insulation at the end of the cables. The length depends on the size

of the wire end sleeves that will be used (1).5. Equip the wire ends with the wire end sleeves (2) as shown Fig. 2.25.6. Press the wire end sleeves with the crimping tool (3) to a quadratic form (4).7. Insert the wires into the terminals and screw down the terminal screws (Fig. 2.26).

Check that all wires are in fixed position. Pay attention to the right polarity.8. Secure both DC wires and the ground wire with the clamp at the rear edge of the

EMI Panel. The distance washers of the clamp should be used for adjusting theclamp for different outer diameters of the wires.

2.6.3 Iub-Interface - Link EquipmentThe Iub interfaces, located on the EMI Panel, provide the communication links to theneighboring Node B stations or the controlling RNC.

The Iub interfaces can be terminated with Overvoltage Protections (OVPT) which pro-tects the boards inside the NB-440/NB-880 against overvoltage (residual voltage < 1kV). Two types of OVPT exist: OVPTE1CF for 75 Ω and OVPTE1J1SF for 100/120 Ωcables.

If this function is not needed, the Iub interfaces will be terminated with an Iub connector(IUBCON). The IUBCONSFV1 is the termination for 100/120 Ω lines and theIUBCONCFV1 for75 Ω lines.

Depending on the different cable impedances it is recommended to:– use screened cable containing 8/10 shielded twisted pairs 0,25 mm2 for 100/120 Ω

PCM lines, e.g. S-09YS(ST)CY 8x2x0.6/1.2.– use coaxial cables for 75 Ω wiring, e.g. 2YCCY 0.4/2.5.

The maximum cable length depends on the attenuation of the cable, in order to fulfill therequirements of minimum voltage levels to be provided at Iub interface according to Iubstandards. The cable shielding must be connected to the relevant ground pins as closeas possible (in order to avoid EMC/RF interfering effects).

2.6.3.1 Iub-Interface for 100/120 Ohm Cable ImpedanceBefore starting the connection of the cables at the Iub-interface of the OVPTE1J1SF orIUBCONCSFV1, prepare the twisted pair cables as shown in the figure below.

Fig. 2.27 Preparation of twisted pair cables, 120 Ohm impedance

i NOTEIf the connection point for the Iub line (network termination) is outside of the buildingwhere the Node B is installed, an OVPT module has to always be installed.

i NOTEUse only twisted pair or coaxial copper cables with braided shielding!If cables should be used without shielded twisted pairs, do not route up-link and down-link PCM lines in one common cable.

1. Cut the cable to the required length; (1).2. Cut back the outer insulation approx.13 cm (5”); (2).3. Remove approx. 11 cm (4.3”) of the braided shield; (3).4. Cut around the outer insulation and shift the insulation ring to the end of the braided

shield; (4). Remove the foil shield and the additional plastic wire.5. Remove 6 mm (1/4”) of the wires insulation.6. Wrap the exposed cable screen, which will be fixed at the stress relieving bracket.

Fig. 2.28 Routing of Iub-cable (example with OVPTE1J1SF)

1. Use straps to fix the cable at the stress relieving bracket.2. Insert the wires into the terminals of the OVPTE1J1SF / IUBCONSFV1.3. Insert the additional wire (shielding potential) into one of the ground terminals.4. Lead the additional wire and the uplink and downlink wires on the shortest way (with-

out sleeves) between the stress relieving bracket and the spring terminals.5. All unconnected Iub lines (4 wires per line) must be connected to one of the ground

terminals.

2.6.3.2 Iub-Interface for 75 Ohm Cable ImpedanceThe coaxial interface is realized by use of 16 1.0/2.3 coaxial connectors, located at theOVPTE1CF or IUBCONCFV1.

Fig. 2.30 Iub interface with coaxial connectors (example with OVPTE1CF)

For coaxial cabling with 75 Ω impedance use coaxial cable e.g. 2YCCY 0.4/2.5.

The coaxial cables will be prepared as follows:

1. Fix a 1.0/2.3 female connector for each Iub up- and down-line at the end to beconnected to the OVPTE1CF or IUBCONCSFV1.

2. Plug-on the prepared cable at the matching connectors.3. Screw the wrap nut of the connector to “finger tight”.

2.6.9 Antenna ConnectionsThe NB-440/NB-880 has to be connected to the transmit/receive antennas. The antennaconfiguration and the required cabling are site-dependent.

For detailed information refer to the site-specific documentation or use the correspond-ing customer documents.

For installation and service purposes it is useful to know which hardware is connectedto which cell. The numbering, seen from the top of the antenna pole, starts at an azimuthangle of 0˚ (north) and rotates clockwise.

The first existing cell whose beam centre line lies at 0˚ or more is defined as cell 0 orsector 0. The next one following in the same sense of rotation is cell 1, etc.

In case of an omni cell the cell no. is 0.

2.6.10 Installation of the Tower Mounted Amplifiers

The Tower Mounted Amplifiers (DTMAF) are the RF units (external to the NodeB rack)which provide the means to feed the overall NodeB downlink signal to one TX/RX an-tenna and to amplify, with low noise figure, the overall NodeB uplink signal coming fromthe same TX/RX antenna.

The DTMARET can additional support the remote electrical tilt (RET) of the antennas inrelation with the DUAMCORETF inside the NodeB and adjusting devices (RET mod-ules) at the antennas. The RET feature allows the adjusting of the horizontal antenna tiltwith a remote control via the O&M.

Fig. 2.51 Position of DTMAF / DTMARETF in the system

The DTMAF / DTMARET should be placed as close to the antenna as possible.

!WARNINGThe electromagnetic field (EMF) generated by a NodeB could have detrimental effectson human health in areas very close to the NodeB antenna. Excessive EMF exposureby the installation/service personnel must be avoided. For installation and maintenanceactivities it is important to know the EMF compliance boundaries in antenna areas.For detailed information please refer to the document:” EN 50385 - Compliance Bound-aries”.Use allways the security equipment for working on poles (S42025-Z159-A4).A second person is needed as an accompaniment during the installation works.

The DTMAF provides two 7/16 female connectors at the bottom for the connection withthe Node B (lettered NodeB 0 and NodeB 1) and on the top both 7/16 connectors forconnecting the jumper cables to the antennas (lettered ANT 0 and ANT 1).

In addition to the RF coaxial connectors, the DTMARETF provides a 8-pole circular con-nector for connecting of the RET module, the tilt adjuster of the antenna.

The DTMAF / DTMARETF shall be grounded to the pole, therefore a grounding wire hasto be prepared for each device on site.

The mounting plate provides a ground screw with a locking washer attached to it and athreaded hole for connection of the grounding wire (see bottom view of the devices). Thegrounding wire cable lug must have the right size for the M8 ground screw. The crosssection of the ground wire must be not less than 16 mm2 (AWG 6).

The other end of the grounding wire should be safely connected to a well grounded pointon the pole.

Care must be taken that the draining pipe (see bottom view of the devices) is pointeddownwards. The draining outlet is factory mounted. If it, for any reason, would be loos-ened, it should be tightened again with a sufficient torque wrench, however not exceed-ing 2.2 Nm (1.6 ft lb).

The draining pipe must never be obstructed or covered with paint which would impedethe venting and draining of the housing.

2.6.10.1 Pole Mounting with Hose ClipsThe hose clips surrounds the pole and are fitted into the corresponding openings of themounting plate (see rear view of the devices). This is the situation just before tighteningthe hose clips.

For the mounting, the following steps can be generally recommended. First connect theDTMAF / DTMARETF to the antenna feeder cable. Take into consideration that the an-tenna feeder often is very stiff and rather heavy. The position of its coaxial connectorstherefore often determines the position of the DTMAF / DTMARETF on the pole.

1. Place the DTMAF / DTMARETF in its final mounting position at the pole.2. Secure the unit with a tensioning belt.3. Open the hose clips by pressing the “button” at the end of the clip lock and then

smoothly pull out the perforated metal band.4. Move the metal band of the hose clip gently into the openings of the mounting plate.5. Close the hose clip loosely around the pole.6. Tighten the hose clip screws carefully, but do not over-tighten (see Fig. 2.63).7. Remove the tensioning belt.8. Connect the DTMAF / DTMARETF first to the antenna feeder cable (NodeB) and

then to the antenna jumper cable (ANT). The torque must be 25 Nm (18.5 ft lb).9. Connect the grounding wire with the DTMAF / DTMARETF ground screw. Tighten

the connection to a torque of 5 Nm (3.7 ft lb).10. The use of self-vulcanizing tape as an environmental protection of the connectors is

recommended.

i NOTEIt is recommended to mount the DTMAF’s and the DTMARETF’s at pole or wall in a ver-tical position, so that the draining outlet of the units is pointing downwards.In certain cases is the mounting in a horizontal position (e.g., on cable runways)possible, it depends on the environmental conditions.

If the antenna is equipped with a RET module, install the DC power / data cable betweenthe module and the 8 pole circular connector of the DTMARETF. The required cable willbe delivered with the RET module together.

The following figures will illustrate the pole mounting procedure of the tower mountedamplifiers.

2.6.10.2 Wall Mounting of DTMAF and DTMARETFThe DTMAF / DTMARET may be mounted on a wall by means of suitable screws anddowels (not supplied with the device).

The corresponding holes in the mounting plate have a diameter of 9 mm (0.35”). Theproper way of mounting the device on a wall varies from case to case. The best methodcan only be decided by the installer. Please note, however, that the wall itself probablydoes not provide adequate grounding, it may be insulated.

2.6.11 Preparation of the Top CoverAfter the connection of external cables, prepare the top cover for setup on the top of therack. The top cover features pre-fractured parts which can be removed in order to routecables through to the infrastructure equipment on site. See figure below.

The required number of pieces can be removed in easy manner by using of a suitablemetal-saw and the following break-out at the perforation. After that refinish the paint coatat all cracks with the paint retouch kit (Siemens Serial No. A500-C101-B261).

Fig. 2.64 Removable pieces and paint retouch of the top cover

!CAUTIONIt is absolutely necessary to prepare and connect an adequate grounding cable to theDTMAF / DTMARET nearest grounding point. The cross section of the ground wiresshould be not less than 16 mm2 (AWG 6).

!CAUTIONPay attention to the thermal dimensional changes of the antenna feeder cables.
