Electrostatic Discharge(ESD) Considerations
Electrostatic discharge (ESD) (for example, caused by touching with the hand) can destroy semiconductor components. The correct operation of the complete system is then no longer assured.
Destruction of components by electrostatic dischargeElectronic components can be destroyed by electrostatic discharge. Circuit packs must always be kept in antistatic covers. Use the original packaging if possible
Use a static ground wrist strap whenever handling circuit packs or working on the Metropolis ® DMXplore system to prevent electrostatic discharge damage to sensitive components.
All semiconductor components are basically sensitive to electrostatic discharge. The electrostatic discharge can also affect the components indirectly using contacts or conductor tracks.
Circuit pack handling precautions
Industry experience has shown that all integrated circuit packs can be damaged by static electricity that builds up on work surfaces and personnel. The static charges are produced by various charging effects of movement and contact with other objects. Dry air allows greater static charges to accumulate. Higher potentials are measured in areas with low relative humidity, but potentials high enough to cause damage can occur anywhere.
Observe the following precautions when handling circuit packs/units to prevent damage by electrostatic discharge:
• Assume all circuit packs contain solid state electronic components that can be damaged by ESD.
• When handling circuit packs (storing, inserting, removing, etc.) or when working on the backplane, always wear a grounded wrist strap such as the one shown in Figure 1, Static Control Wrist Strap (page -xxiv) or wear a heel strap and stand on a grounded, static dissipating floor mat. If a static dissipating floor mat is used, be sure that it is clean to ensure a good discharge path.
About this information productSafety Information and Instructions
• Wear working garment made of 100% cotton to avoid electrostatic discharge.
• Handle all circuit packs by the faceplate or latch and by the top and bottom outermost edges. Never touch the components, conductors, or connector pins.
• Store and ship circuit packs and components in their shipping packing. Circuit packs and components must be packed and unpacked only at workplaces suitably protected against build-up of charge.
• Observe warning labels on bags and cartons. Whenever possible, do not remove circuit packs from antistatic packaging until ready to insert them into slots.
• If possible, open all circuit packs at a static safe work position, using properly grounded wrist straps and static dissipating table mats. If a static dissipating floor mat is used, be sure that it is clean to ensure a good discharge path.
• Always store and transport circuit packs in static safe packaging. Shielding is not required unless specified.
• Keep all static generating materials such as food wrappers, plastics, and styrofoam containers away from all circuit packs. Upon removal from bay, immediately put circuit packs into static safe packages.
To reduce the possibility of ESD damage, assemblies are equipped with grounding jacks to enable personnel to ground themselves using wrist straps (Figure 1, Static Control Wrist Strap (page -xxiv)) while handling circuit packs or working on an assembly. The jacks for connection of wrist straps are located at the upper right-hand corner of each assembly and are labeled. When grounding jacks are not provided, an alligator clip adapter enables connection to bay frame ground.

Introduction This section provides instructions for mounting the Metropolis®
DMXplore Wall-Mount on a wall and in the supported bay-frames sizes using the appropriate bracket.
Installation Notes:
1. When wall mounting 3" top clearance, 1" bottom clearance, and .5" side clearances are required for natural convection cooling.
2. When mounting the Metropolis® DMXplore unit above power dissipating equipment an appropriate heat baffle is required. Maximum operating temperature is 65° C.
3. When being used in an outdoor cabinet (or other environments allowing for ambient temperatures up to 65° C), the minimum required airflow is 200 fpm.
4. The maximum weight of the Metropolis® DMXplore Wall-Mount shelf, fully equipped is 4.77kg (10.5 lbs).
Wall installation The Metropolis® DMXplore Wall-Mount is a front access design that allows for it to be mounted directly against a flat surface. The following steps describe mounting the shelf on a wall.
Installation Note:
Wall mount mounting hardware is included with the Wall-Mount
Metropolis® DMXplore shelf code.
Procedure
Step 1 Position the Metropolis® DMXplore shelf on a stable work surface.
Important! Front cover is shipped with a clear protective liner over the outside surface of the viewing window of cover. Peel and remove. See Figure 1-2, Metropolis® DMXplore Shelf Wall-Mount (with Cover) (page 1-10).
Step 2 Remove wall-plate from the rear of the Wall-Mount Metropolis®
DMXplore Shelf by doing the following:
1. Loosen the mounting screw in the top right hand corner of the Access Panel. See Figure 1-2, Metropolis® DMXplore Shelf Wall-Mount (with Cover) (page 1-10).
2. Slide shelf up along wall plate until it clears the mounting tabs. See Figure 1-3, Mounting Screw (page 1-10)
Step 4 Secure the wall plate to 3/4" plywood or wall studs at the desired location using included #8 X .75" long Pan Head Wood Screws (4 supplied with the shelf).
Important! See Installation Notes: (1-9) for required clearances.
Step 5 Position the Metropolis® DMXplore shelf onto the mounting tabs and secure to wall plate using the mounting screw. See Figure 1-3, Mounting Screw (page 1-10).
Step 7 Verify with an ohmmeter that the Metropolis® DMXplore shelf is grounded properly. Measure between the Metropolis® DMXplore shelf safety ground screw and the appropriate safety ground.
Step 8 Verify with an ohmmeter that the ESD jack on the front of the shelf is grounded properly. Measure between the ESD jack stud and the appropriate safety ground.
Step 9 If using the AC/DC converter (408812394), mount it at least 3" above the DMXplore with its 3’ DC cable towards the DMXplore and its AC connection facing up, away from the DMXplore .
12-inch, 19-inch, and 23-Inch Bay-frame Installation
As an example of the Metropolis® DMXplore shelf installation, the following steps describe mounting a single shelf from the front of a 23-inch bay-frame. Mounting from the rear of a 23-inch bay-frame or from the front/rear of a 12-inch or 19-inch bay-frame is similar with the exception of the type and mounting position of the brackets.
See Figure 1-8, Wall-Mount Bay-Frame Mounting Brackets (page 1-17)
The 23-inch frame supports two Metropolis® DMXplore shelves. To mount a second shelf repeat this procedure for the second shelf at the second mounting position.
Important! This section requires previous bay-frame installation and grounding.
Procedure
Step 1 Position the Metropolis® DMXplore shelf on a stable work surface.
Important! Front cover is shipped with a clear protective liner over the outside surface of the viewing window of cover. Peel and remove. See Figure 1-2, Metropolis® DMXplore Shelf Wall-Mount (with Cover) (page 1-10).
Step 2 Determine the mounting configuration for the Metropolis® DMXplore shelf:
• type of bay-frame (23-inch, 19-inch or 12-inch wide)
• mounting position (front, rear)
• shelf position for 23-inch frame (right, left)
• position in bay (bottom to top)
Important! The mounting brackets must be ordered separately and are required to install the Metropolis® DMXplore in a bayframe. See Tools, Test Equipment and Accessories (1-3)
Important! If mounting two Metropolis® DMXplore shelves in a 23" rack application cable access is moderately restricted.
Important! A front mounting position results in a 5" protrusion from the front of bay-frame.
Step 4 Determine the position that the bay-frame mounting bracket will be mounted. As a general rule, start at the bottom of the bay and add shelves from bottom to top.
Important! If the Metropolis® DMXplore shelf is to be installed above or below existing equipment that does not have a heat baffle, then a heat baffle (C848862181) must be installed between the shelf and the existing equipment.
Important! If there is space left in the bayframe above the last Metropolis® DMXplore bracket assembly installed, a heat baffle
Step 5 Position the bay-frame mounting bracket in the frame and secure to the frame using 3 thread-forming screws side (not included). Tighten the screws to 21 in.-lb. (minimum)/30 in.-lb. (maximum)
Important! Grounding wire must be of the same gauge as the cables used to power the shelf.
Important! Be sure to mount the shelf using thread-forming screws to ensure a solid ground connection from the bay to the shelf.
Important! For bays that use powder coat paint e.g. most 19" bays, studies on that type of paint indicate that the material is not always removed cleanly using the thread forming screws and can create a poor ground, thus we recommend a secondary ground be used. The secondary ground would consist of a 12 AWG wire from the UL (Green M5 Screw) safety ground to the bayframe (where the bayframe has been scraped clean of paint and treated with no-ox) See Figure 1-7, Safety Ground Screw (page 1-15).
Step 11 Verify with an ohmmeter that the ESD Jack Stud See Figure 1-2, Metropolis® DMXplore Shelf Wall-Mount (with Cover) (page 1-10) is grounded to the bay-frame. Measure between the ESD Jack Stud and the safety ground lug on the bay-frame.
Requirement: The ohmmeter reads less than 1 ohm.
Important! If using the AC/DC converter (408812394), it may be desirable to mount the converter(s) to the rear of the shelf at this time. A single converter can be mounted on the rear of the 12" and 19" mounting brackets, whereas the 23" mounting bracket supports up to two AC/DC converters.
Description This section provides instructions on installing the power cabling for the Metropolis® DMXplore shelf.
Each power feeder (A and B) requires a single power feed from; the AC/DC power converter (408812394), the battery distribution fuse board (BDFB), or the battery distribution circuit breaker bay (BDCBB) to the Metropolis® DMXplore shelf.
If the Metropolis® DMXplore is powered through only one power feed, the system will report a minor alarm. To suppress the alarm, use two jumpers between the 48VA and 48 VB attachment positions (A- to B- and A+ to B+). The gauge of both jumpers should be the same as the gauge being brought in from either the Battery Plant or from the MASCOT AC/DC Supply (#12AWG to #20AWG).
Table 1-2, Power Cable Assemblies and Table 1-3, Power Connections (page 1-18) lists the available power cable assemblies and power connections, respectively.
CAUTIONVerify that the AC/DC converter is not plugged into the AC power outlet, or that BDCBB breakers are off, or that the BDFB fuses are not installed.
Step 2 Connect the A and B power cables to the A and B connector pins of the terminal block located on the top right of the access panel. Use a torque screwdriver set to 0.5 Nm (4.4 lb-in) to tighten. See Figure 1-9, Power Connection (page 1-20).
Important! Power cables must be between 12 AWG and 20 AWG and have an 8mm wire strip length for connection to the terminal block.
Step 9 Leave the power supply mechanism disconnected at the power source until you are ready to perform the procedures in Chapter 3, Powering and Initial Circuit Pack Installation for Metropolis® DMXplore Shelf (Wall-Mount) of this manual.
Description This section describes how to connect the DS1 transmission cables to the A/D function group of the shelf. If applicable, route the cables out of the bay and connect the cables to the DSX panel.
Important! When cabling the Metropolis® DMXplore to a DSX, the DSX becomes an extension of the Metropolis® DMXplore access panel connections. Thus the IN on the Metropolis®
DMXplore access panel connects to the IN of the DSX and the OUT of the Metropolis® DMXplore access panel connects to the OUT of the DSX respectively.
The cables are connectorized at the Metropolis® DMXplore end and may be needed to be wire-wrapped at the DSX end if equipped with a blunt connection end. The A function group supports a maximum of 16 DS1 drop capacity.
Important! The A/D function group is a dual purpose slot. In the current release the A/D slot is identified as the A function group. Future releases will add new functionality and refer to the A/D slot as the D function group.
Table 1-5, DS1 Cable Assemblies and Table 1-6, DS1 Transmission Connections (page 1-24) lists the available DS1 cable assemblies and DS1 connections, respectively.
Step 1 Refer to the engineering job specification. Obtain the DS1 cables per Table 1-5, DS1 Cable Assemblies (page 1-23). Label the cables, indicating bay and shelf, and direction (IN or OUT of the bay) at each end. See Table 1-6, DS1 Transmission Connections (page 1-24) for associated color coding.
Important! Blunt-end cables that are to be wire wrapped will need to be labeled IN or OUT. Cable ends terminated using a RJ-45 connector will not need to be labeled using the IN and OUT designation because both are supported by the connector.
Step 2 Connect the RJ-45 end of a single cable to the respective RJ-45 Receptacle on the access panel as shown in Figure 1-10, DS1 Access Panel Cable Connectors (page 1-25).
Description This section describes how to connect the DS3 transmission cables to the B function group of the shelf. If applicable, route the cables out of the bay and connect the cables to the DSX panel.
Important! When cabling the Metropolis® DMXplore to a DSX, the DSX becomes an extension of the Metropolis® DMXplore access panel connections. Thus the IN on the Metropolis®
DMXplore access panel connects to the IN of the DSX and the OUT of the Metropolis® DMXplore access panel connects to the OUT of the DSX, respectively.
The cables are connectorized at the Metropolis® DMXplore end and will need to be connected to the appropriate BNC termination at the other end. The B function group supports a maximum of two DS3 drop capacity.
DS3 cable options are listed in Table 1-7, DS3 Cable Assemblies (page 1-27).
Step 1 Refer to the engineering job specification. Obtain the DS3 cables per Table 1-7, DS3 Cable Assemblies and note the function group where each cable will be used. Label the cables, indicating bay, shelf, function group (B) and direction (IN or OUT of the bay) at each end.
Step 2 Connect one end of the cable to the respective Receptacle on the access panel as shown in Figure 1-12, DS3 Access Panel Cable Connectors. (page 1-28).
Overview This section describes how to route the Fast Ethernet (10/100Base T) cables from the Wall-Mount Metropolis® DMXplore shelf to the 10/100BaseT terminating equipment.
If Fast Ethernet Cabling is not available yet, this section may be completed later.
Procedure Refer to Figure 1-13, 10/100Base-T Cable Installation (page 1-31) when performing this procedure.
Step 1 Obtain the 10/100BaseT cables per Table 1-8, LAN 10/100 BaseT Cable Assemblies for Fast Ethernet
Description Office alarms are the common method used in a central office for maintenance personnel to quickly isolate a failure. Perform this procedure if connection to the office alarm system is required.
Important! The office alarm relay contacts are rated at 50 VA which means that they are capable of switching 1 amp at 50 volts, or 2 amps at 25 volts. Their ability to switch large transient currents means that they can, if necessary, switch up to ten 5-watt aisle pilot lamps.
If transient voltages or currents are above these limits, transient noise-suppressing devices such as diodes or contact protection networks must be used to keep within the voltage and current limits. If these protection devices are not sufficient, an external buffer relay MUST be provided.
In all cases, and as a matter of good practice, suppression devices such as diodes or contact protection networks must be provided across any external relay coil being driven by the Metropolis® DMXplore to limit transient voltages and currents.
Office alarm cable assemblies are listed in Table 1-9, Office Alarm Cable Assemblies (page 1-33) and Office alarm connection are listed in Table 1-10, Office Alarm Connections (page 1-34).

Notes:
1. Miscellaneous Discrete and Alarm cables are identical and thus have the same comcode.
Step 1 Obtain the office alarm cable per Table 1-9, Office Alarm Cable Assemblies (page 1-33). Connect the office alarm cables to the ALARM terminal block in the lower left hand corner of the access panel. See Figure 1-14, Office Alarm Cable Connections (page 1-35)
Important! The recommended wire strip length for cables being connected to the alarm block is 11mm.
Step 5 Wire-wrap the loose end of the office alarm cable to the alarm panel, making connections as listed in Table 1-10, Office Alarm Connections (page 1-34).
Description The miscellaneous (environmental) discrete telemetry access allows the maintenance center to control and monitor equipment collocated with the Metropolis® DMXplore.
The environmental control feature enables the maintenance center to remotely initiate up to four contact closures at the remote terminal (RT) for equipment operation such as pumps, generators, etc.
The environmental alarm status indications allow up to 4 miscellaneous user-settable alarm status indications (SI) at the remote terminal for transmission toward the central office.
Miscellaneous (environmental) discrete telemetry cable assemblies and connections are listed in Table 1-11, Miscellaneous Discrete Cable Assemblies (page 1-37) and Table 1-12, Miscellaneous (Environmental) Discrete Telemetry Connections (page 1-38), respectively.
Step 2 Route the miscellaneous (environmental) discretes cables to the telemetry panel as shown in Figure 1-17, Miscellaneous Discretes and Office Alarm Cable Routing (page 1-40).
Important! Miscellaneous Discrete connections and Alarm connections may be dressed together in a single bundle.
Step 4 Wire-wrap the loose end of the miscellaneous (environmental) discrete telemetry cable to the wire-wrap terminal strip, making connections per Table 1-12, Miscellaneous (Environmental) Discrete Telemetry Connections (page 1-38).
Important! Each miscellaneous (environmental) discrete telemetry designation is connected to the Metropolis® DMXplore by two leads (wires). For each input, one lead should be connected to input-common and the other lead should be connected to the appropriate alarm indication. For each output, one lead should be connected to output-common and the other lead should be connected to the appropriate alarm indication.
Description This section describes how to route the optical fiber cables from the interconnecting equipment (for example, a LGX® optical fiber distributing frame) to the Main OLIUs of the Metropolis® DMXplore. This procedure does not cover routing the optical fiber cable between sites.
The optical fiber cables are connected to the Metropolis® DMXplore after the circuit packs are installed. The Metropolis® DMXplore requires single-mode fiber for the main OLIUs. See ED8C947-10 Common Systems, Metropolis® DMXplore Access Multiplexer, Engineering and Ordering Information for recommended fibers.
Important! The optical fiber cable is fragile and must be protected. The fibers should be placed in a protective tube or channel, such as PVC tubing, or PANDUIT cable channel, when running the cable from the Metropolis® DMXplore to the cable rack. The fibers should be placed in the cable rack in a protective channel with nothing on top of them. Cable ties should NOT be used with the optical fiber cables.
WARNINGUnterminated optical connectors may emit laser radiation. Do not view an unterminated optical connector with optical instruments. Avoid direct exposure of the eyes to the beam.
Important! Prior to connecting the optical fiber cables, the fibers should be examined to ensure that they are clean. See Appendix B, Fiber Cleaning for recommended cleaning procedures.

Each power feeder (A and B) requires a single power feed from; the AC/DC power converter (408812394), the battery distribution fuse board (BDFB), or the battery distribution circuit breaker bay (BDCBB) to the Metropolis® DMXplore shelf.
If the Metropolis® DMXplore is powered through only one power feed, the system will report a minor alarm. To suppress the alarm, use two jumpers, one jumper between the -48VA and -48 VB and the second jumper between RTN-A and RTN-B. See Figure 2-7, Power Connection (page 2-15) for location. The gauge of both jumpers should be the same as the gauge being brought in from either the Battery Plant or from the MASCOT AC/DC Supply (#12AWG to #20AWG).
Table 2-2, Power Cable Assemblies and Table 2-3, Power Connections (page 2-14) lists the available power cable assemblies and power connections, respectively.
Important! To tie RTN-A and RTN-B together use a MESH Ground Strap to jumper between RTN-COM and GND of the power terminal block. See Figure 2-7, Power Connection (page 2-15) for location.
CAUTIONVerify that the AC/DC converter is not plugged into the AC power outlet, or that BDCBB breakers are off, or that the BDFB fuses are not installed.
torque screwdriver set to 0.5 Nm (4.4 lb-in) to tighten. See Figure 2-7, Power Connection (page 2-15).
Important! Power cables must be between 12 AWG and 20 AWG and have an 8mm wire strip length for connection to the terminal block. Use the guide located on the inside of the cover on the lower right hand for accurate lengths.
Step 9 Leave the power supply mechanism disconnected at the power source until you are ready to perform the procedures in Chapter 4, Powering and Initial Circuit Pack Installation for Metropolis® DMXplore Shelf (Rack-Mount) of this manual.
Important! The BDFB requires the removal of fuses to inhibit power flow.
Description This section describes how to connect the DS1 transmission cables to the A/D function group of the shelf. If applicable, route the cables out of the bay and connect the cables to the DSX panel.
Important! When cabling the Metropolis® DMXplore to a DSX, the DSX becomes an extension of the Metropolis® DMXplore access panel connections. Thus the IN on the Metropolis®
DMXplore access panel connects to the IN of the DSX and the OUT of the Metropolis® DMXplore access panel connects to the OUT of the DSX respectively.
The cables are connectorized at the Metropolis® DMXplore end and may be needed to be wire-wrapped at the DSX end if equipped with a blunt connection end. The A function group supports a maximum of 16 DS1 drop capacity.
Important! The A/D function group is a dual purpose slot. In the current release the A/D slot is identified as the A function group. Future releases will add new functionality and refer to the A/D slot as the D function group.
Table 2-5, DS1 Cable Assemblies and Table 2-6, DS1 Transmission Connections (page 2-19) lists the available DS1 cable assemblies and DS1 connections, respectively.
Step 1 Refer to the engineering job specification. Obtain the DS1 cables per Table 2-5, DS1 Cable Assemblies (page 2-18). Label the cables, indicating bay and shelf, and direction (IN or OUT of the bay) at each end. See Table 2-6, DS1 Transmission Connections (page 2-19) for associated color coding.
Important! Blunt-end cables that are to be wire wrapped will need to be labeled IN or OUT. Cable ends terminated using a RJ-45 connector will not need to be labeled using the IN and OUT designation because both are supported by the connector.
Step 2 Connect the RJ-45 end of a single cable to the respective RJ-45 Receptacle on the access panel on the drear of the Rack-Mount Metropolis® DMXplore shelf as shown in Figure 2-8, DS1 Access Panel Cable Connectors (page 2-20).
Description This section describes how to connect the DS3 transmission cables to the B function group of the shelf. If applicable, route the cables out of the bay and connect the cables to the DSX panel.
Important! When cabling the Metropolis® DMXplore to a DSX, the DSX becomes an extension of the Metropolis® DMXplore access panel connections. Thus the IN on the Metropolis®
DMXplore access panel connects to the IN of the DSX and the OUT of the Metropolis® DMXplore access panel connects to the OUT of the DSX, respectively.
The cables are connectorized at the Metropolis® DMXplore end and will need to be connected to the appropriate BNC termination at the other end. The B function group supports a maximum of two DS3 drop capacity.
DS3 cable options are listed in Table 2-7, DS3 Cable Assemblies (page 2-22).
Step 1 Refer to the engineering job specification. Obtain the DS3 cables per Table 2-7, DS3 Cable Assemblies and note the function group where each cable will be used. Label the cables, indicating bay, shelf, function group (B) and direction (IN or OUT of the bay) at each end.
Step 2 Connect one end of the cable to the respective Receptacle on the access panel on the rear of the Rack-Mount Metropolis® DMXplore shelf as shown in Figure 2-9, DS3 Access Panel Cable Connectors (page 2-23).
Overview This section describes how to route the Fast Ethernet (10/100Base T) cables from the Rack-Mount Metropolis® DMXplore shelf to the 10/100BaseT terminating equipment.
If Fast Ethernet Cabling is not available yet, this section may be completed later.
Procedure Refer to Figure 2-10, 10/100Base-T Cable Installation (page 2-24) when performing this procedure.
Step 1 Obtain the 10/100BaseT cables per Table 2-8, LAN 10/100 BaseT Cable Assemblies for Fast Ethernet
Description Office alarms are the common method used in a central office for maintenance personnel to quickly isolate a failure. Perform this procedure if connection to the office alarm system is required.
Important! The office alarm relay contacts are rated at 50 VA which means that they are capable of switching 1 amp at 50 volts, or 2 amps at 25 volts. Their ability to switch large transient currents means that they can, if necessary, switch up to ten 5-watt aisle pilot lamps.
If transient voltages or currents are above these limits, transient noise-suppressing devices such as diodes or contact protection networks must be used to keep within the voltage and current limits. If these protection devices are not sufficient, an external buffer relay MUST be provided.
In all cases, and as a matter of good practice, suppression devices such as diodes or contact protection networks must be provided across any external relay coil being driven by the Metropolis® DMXplore to limit transient voltages and currents.
Office alarm cable assemblies are listed in Table 2-9, Office Alarm Cable Assemblies (page 2-26) and Office alarm connection are listed in Table 2-10, Office Alarm Connections (page 2-27).

Notes:
1. Miscellaneous Discrete and Alarm cables are identical and thus have the same comcode.
Step 1 Obtain the office alarm cable per Table 2-9, Office Alarm Cable Assemblies (page 2-26). Connect the office alarm cables to the ALARM terminal block in the lower left hand side of the access panel on the rear of the Rack-Mount Metropolis® DMXplore shelf. See Figure 2-12, Office Alarm Cable Connections (page 2-28) and Figure 2-11, Alarm Designations (as shown on inside cover) (page 2-28) for details.
Important! The recommended wire strip length for cables being connected to the alarm block is 11mm. Use the guide located on the inside of the cover on the lower right hand for accurate lengths.
Step 5 Wire-wrap the loose end of the office alarm cable to the alarm panel, making connections as listed in Table 2-10, Office Alarm Connections (page 2-27).
Description The miscellaneous (environmental) discrete telemetry access allows the maintenance center to control and monitor equipment collocated with the Metropolis® DMXplore.
The environmental control feature enables the maintenance center to remotely initiate up to four contact closures at the remote terminal (RT) for equipment operation such as pumps, generators, etc.
The environmental alarm status indications allow up to 4 miscellaneous user-settable alarm status indications (SI) at the remote terminal for transmission toward the central office.
Miscellaneous (environmental) discrete telemetry cable assemblies and connections are listed in Table 2-11, Miscellaneous Discrete Cable Assemblies (page 2-30) and Table 2-12, Miscellaneous (Environmental) Discrete Telemetry Connections (page 2-31), respectively.
Step 4 Wire-wrap the loose end of the miscellaneous (environmental) discrete telemetry cable to the wire-wrap terminal strip, making connections per Table 2-12, Miscellaneous (Environmental) Discrete Telemetry Connections (page 2-31).
Important! Each miscellaneous (environmental) discrete telemetry designation is connected to the Metropolis® DMXplore by two leads (wires). For each input, one lead should be connected to input-common and the other lead should be connected to the appropriate alarm indication. For each output, one lead should be connected to output-common and the other lead should be connected to the appropriate alarm indication.
Description This section describes how to route the optical fiber cables from the interconnecting equipment (for example, a LGX® optical fiber distributing frame) to the Main OLIUs of the Rack-Mount Metropolis®
DMXplore. This procedure does not cover routing the optical fiber cable between sites.
The optical fiber cables are connected to the Metropolis® DMXplore after the circuit packs are installed. The Metropolis® DMXplore requires single-mode fiber for the main OLIUs. See ED8C947-10 Common Systems, Metropolis® DMXplore Access Multiplexer, Engineering and Ordering Information for recommended fibers.
Important! The optical fiber cable is fragile and must be protected. The fibers should be placed in a protective tube or channel, such as PVC tubing, or PANDUIT cable channel, when running the cable from the Metropolis® DMXplore to the cable rack. The fibers should be placed in the cable rack in a protective channel with nothing on top of them. Cable ties should NOT be used with the optical fiber cables.
WARNINGUnterminated optical connectors may emit laser radiation. Do not view an unterminated optical connector with optical instruments. Avoid direct exposure of the eyes to the beam.
Important! Prior to connecting the optical fiber cables, the fibers should be examined to ensure that they are clean. See Appendix B, Fiber Cleaning for recommended cleaning procedures.
Step 1 Snap the fiber management module into place on the left of the Rack-Mount Metropolis® DMXplore. See Figure 2-15, Optical Fiber Routing (page 2-35)
Step 2 Route the optical fiber cables from the interconnecting equipment through the fiber management module and into the left side of the Rack-Mount Metropolis® DMXplore. Protective covers must be left on cables.
Step 4 Label the optical fiber cables, indicating bay, shelf, pack, and direction (IN or OUT). See Appendix F, Fiber Labeling for more details. The fibers will be inserted into the equipment later, once the circuit packs are installed.

1. The connection and the colors shown above are for a standard Lucent-made cable. If you use a RJ-45 to DB-9 connector with a standard straight-through 10BASE-T LAN cable then, refer to Table 2-15, RJ-45 to DB-9 Connector Connections (page 2-38).
Description This section describes how to connect the IAO LAN/TCP-IP (LAN 10BASE-T) cable to the Metropolis® DMXplore shelf and to the interfacing equipment. Perform this procedure if this cabling is required.
Metropolis® DMXplore supports an IntraOffice LAN (IAO LAN) interface for operations data communications to support operations systems such as the Navis Optical EMS (formerly WaveStar SNMS).
Since the IAO LAN can be provisioned as an extension of the SONET DCC, the IAO LAN can also be used to join multiple, otherwise separate subnetworks.
All NE-to-NE OI features that are supported over the DCC are also supported over the IAO LAN.
The IAO LAN/TCP-IP interface cable is available in two configurations (cross-over and straight-through) and is connected to the front of the Metropolis® DMXplore shelf. The following tables provide additional information:
• Table 2-16, LAN 10BASE-T Cable Assemblies (page 2-39)
• Table 2-17, LAN 10BASE-T Cross-over Cable Connections (page 2-41)
• Table 2-18, LAN 10BASE-T Straight-through Cable Connections (page 2-41)
Step 1 Connect the cable to the LAN (RJ45) jack on the SYSCTL circuit pack.
Important! If connecting directly to a PC, use a LAN 10BASE-T Cross-over Cable Assembly (See Table 2-17, LAN 10BASE-T Cross-over Cable Connections).
Important! If connecting to a hub, use a LAN 10BASE-T Straight-through Cable Assembly (See Table 2-18, LAN 10BASE-T Straight-through Cable Connections).

Ring Setup and Testing: Integration ProceduresOverview
Before beginning this procedure check PC Minimum Requirements (page 5-2) to ensure the PC you are using meets the minimum requirements necessary.
Safety Instructions Important! All precautions should be observed when handling fiber.
WARNINGUnterminated optical connectors may emit laser radiation. Do not view beam with optical instruments.
CAUTIONThe operational tests in this section are run only in an out-of-service mode of operation. Office alarms will normally be connected only during the office alarm test to prevent constant alarms throughout this section.
Procedure The following procedures are performed at each end of the optical span being tested.
Step 1 Verify that the office alarm cabling to the ALARM terminal block on the access panel of the Metropolis® DMXplore shelf is disconnected. If the shelf to be tested is part of a multiple shelf bay arrangement, the office alarm cable connects to shelf 1.
Step 2 At each DMXplore shelf, enter the shelf TID per the customer order or use LT-DMXPLORE-1 and LT-DMXPLORE-2 as defaults using the ENT-SYS command.
Step 3 Use the scroll bar in the Command Builder window to scroll down to the dlt-crs-zzz command. Select x-1-all under <zzzAIDCRSSRC> and m-1-{1}-all under <zzzAIDCRSDST>.

Ring Setup and Testing: Integration ProceduresFiber Installation
Step 15 At both ends of the optical span, remove protective covers from receive and transmit optical jumper cables and clean LC connectors.
Important! The Metropolis® DMXplore OLIUs require single-mode lightguide cable. Single-mode optical fibers connecting this shelf with the far-end shelf should not be connected to the OLIU until at least 45 seconds after an optical loopback is removed. It may take from 15 seconds to 3.5 minutes for the FAULT LEDs to stop flashing after the cables are connected, depending on the setting of the OC-3/OC-12 signal degrade threshold.
Step 16 At both ends of the optical span, ensure that only the dual LC adapter is installed on the OLIU (no LBO).
Important! For Metropolis® DMXplore OC-3/OC12 UPSR ring configurations, optical fibers extend in two different directions to make up the ring. At each shelf (node) in the ring, the M1 OLIU will connect to the M2 OLIU in one adjacent node, and the M2 OLIU will connect to the M1 OLIU in the other adjacent node.
When the Metropolis® DMXplore is interfacing with other equipment such as a Metropolis® DMX Access Multiplexer at low-speeds (OC-3/OC12) using 1+1 protection, the Main 1 of the DMXplore will connect to the slot 1 of the function Group (e.g. A1, B1, C1, D1, or G1 for the Metropolis® DMX Access Multiplexer). The Main 2 of the DMXplore will connect to the slot 2 of the function Group (e.g. A2, B2, C2, D2, or G2 for the Metropolis® DMX Access Multiplexer).
Step 19 Select the appropriate LBO value required based on the received optical power measurement. Attenuate to the middle of the allowable optical receive power range. Refer to the following table for the DMXplore Main circuit pack receive levels.
Step 25 Disconnect the fiber cable from the OUT connector on the OLIU at one end of the span. At the other end, verify that the associated FAULT LED is flashing, indicating a loss of signal. Reconnect the fiber and repeat the process for the other direction of transmission.
Step 31 After all connections and tests have been made, verify optical fiber cables are placed in the fiber slots on the left side of the shelf and properly routed in bay framework.
Procedure This procedure should be conducted when the Metropolis® DMXplore Access Multiplexer shelf is set to UPSR and connected end to end and not looped back on itself.
Step 1 Use the scroll bar in the Command Builder window to scroll down to the init-reg-all command.

System design The Lucent Technologies system complies with FDA/CDRH 21 CFR 1040.10 and 1040.11 as a Class I and with IEC 60825-1 as a Class 1 Optical Fiber Telecommunication laser product. The system has been designed to ensure that the operating personnel is not endangered by laser radiation during normal system operation. The safety measures specified in the Food and Drug Administration’s Center for Devices and Radiological Health (FDA/CDRH) regulations and the international standards IEC-60825 or DIN/EN 60825 are met. Please also refer to Laser Product Classification (page -5).
Potential sources of danger Beware of the following potential sources of danger which will remain despite all safety measures taken:
• Laser radiation can cause damage to the skin and eyes.
• Laser radiation from optical transmission systems is in a wavelength range that is invisible to the human eye.
Laser warning labels The laser warning labels indicate either only the laser class or both the laser class and the maximum output power of laser radiation. The following figure shows different types of laser warning labels and their characteristics.
Laser warning symbol
This laser warning label is affixed on the outside of the front cover
This warning label is affixed to the inside of the subrack.
Laser safety instructions Observe the following instructions to avoid exposing yourself and others to risk.
• Read the relevant descriptions in the manuals before taking equipment into operation or carrying out any installation and maintenance work on the optical port units, and follow the instructions. Ignoring the instructions can result in exposure to dangerous radiation.
• Do not view directly into the laser beam with optical instruments such as a fiber microscope, because viewing of laser emission in excess of Class 1 limits significantly increases the risk of eye damage.
• Never look into the end of an exposed fiber or an open connector as long as the optical source is still switched on.
• Ensure that the optical source is switched off before disconnecting optical fiber connectors.
• In the event of doubt, check that the optical source is switched off by measuring with an optical power meter.
Standards compliance The product complies with both IEC standards and the Food and Drug Administration’s Center for Devices and Radiological Health (FDA/ CDRH) regulations.
FDA/CDRH regulations Laser products are classified in accordance with the FDA/CDRH - 21 CFR 1010 and 1040. The classification scheme is based on the ability of the laser emission to cause injury to eye or skin during normal operating conditions.
In the United States, lasers and laser systems in the infrared wavelength range (greater than 700 nm) are assigned to one of the following classes:
• Class I,
• Class IIIb, or
• Class IV.
Laser classification is dependent upon operating wavelength, output power and fiber modefield diameter (core diameter).
IEC requirements The International Electro-Technical Commission (IEC) establishes standards for the electrical and electronic industries. IEC-60825 has been established for the worldwide safety of laser products.
According to the IEC classification, lasers and laser systems in the infrared wavelength range (greater than 700 nm) are assigned to one of the following classes:
• Class 1,
• Class 3A,
• Class 3B, or
• Class 4.
There are some major differences between the FDA/CDRH regulations and IEC:
1. The Accessible Emission Limits (AEL) are different.
2. Class 3A applies to all wavelengths.
3. Class 3B requires strict engineering controls.
4. Classification is under single fault conditions.
Laser Safety and ClassificationsLaser Product Classification
A - 6 365-372-334 R2.0Issue 4, November 2004
Laser classes The maximum output power of laser radiation depends on the type of laser diode used. The international standards IEC-60825 or DIN/EN 60825 define the maximum output power of laser radiation for each laser class in accordance with the wavelength.
Hazard level assignment Hazard level refers to the potential hazard from laser emission at any location in an end-to-end optical fiber communication system that may be accessible during service or in the event of a failure. The assignment of hazard level uses the AELs for the classes.
Hazard levels for optical transmission equipment are assigned in either of the following two ways:
• actual output power from the connector or fiber cut.
• if automatic power reduction is used, output power at the connector or fiber cut at one second after automatic power reduction takes place provided that maximum output and restart conditions are met.
Classification of opticaltelecommunication
equipment
Optical telecommunication equipment is generally classified as IEC Class 1 or FDA/CDRH Class I, because under normal operating conditions, the transmitter ports terminate on optical fiber connectors. These are covered by a front panel to ensure protection against emissions from any energized, unterminated transmitter. The circuit packs themselves, however, may be IEC Class 1 or 3A or FDA/CDRH Class I or IIIb.
Purpose This appendix describes the Lucent recommended method for the cleaning and inspection of optical connectors using specific tools and materials that have been proven to be effective in the assembly and testing of optical transmission equipment. It is critical that connector faces are clean and free from particular contamination to assure proper performance and reliability of lightwave systems. With the modern high speed, high power, and wider bandwidth optical transmission systems, clean connectors along the optical path are essential for successful operation.
Contents This appendix provides information on the following topics:

Description For proper cleaning, the following equipment and materials are recommended:
Important! The equipment and material listed above has been tested and is proven effective when used in conjunction with this procedure. Substitution of equipment or materials is at the discretion of the user and is not recommended.
Luminex Cloth 5.5” x 5.5” 408201226 R6033 23603300
Notes:
1. This equipment may not be necessary at all locations. It is to be used when the ports need to be verified for cleanliness. If care is exercised when cleaning fibers, the video scope may not be needed.
WARNINGNever view an energized optical cable with the naked eye or with an optical magnifying instrument. Disconnected or separated optical connectors may emit invisible laser radiation and direct exposure can severely injure the eye. If inspecting the endface of a connector with a fiberscope, be absolutely certain that the system is deactivated.
WARNINGAlcohol is flammable and is harmful if swallowed, inhaled or absorbed through the skin. Keep alcohol away from heat, sparks, or flame. Avoid contact with eyes, skin and clothing.
Introduction The procedure that follows utilizes the “Wet/Dry” method for connector cleaning. This method first applies a “wet” solvent such as high purity alcohol to the connector endface to dissolve/remove any organic particulate or oily films, followed by a “dry” double clean wipe using the CLETOP cleaning cassette.
This procedure is recommended for connector ferrules 2.5 mm and 1.25 mm in diameter associated with ST, SC, FC, and LC connectors. The ferrule of a fiber optic connector consists of a ceramic or stainless steel cylinder with a hole located longitudinally down the center of its axis, allowing enough tolerance for a fiber to pass through.
All optical connectors should be cleaned prior to being connected. Keep the protective ferrule dust cap on the connector until initiating the cleaning process.
Step 2 Open an individual foil packet of pre-saturated isopropyl alcohol (99% pure) wipe.
See Figure B-1, Cleaning the Ferrule Endface (page -6).
Grasp the connector housing and place the connector ferrule endface perpendicular to the alcohol wipe.
Drag it against the wipe three (3) times in a figure eight pattern. This action applies the alcohol solvent to the endface and initially loosens and scrubs away organic/solid contaminates.
Step 3 If a CLETOP cassette cleaner is not available, proceed with Step 7. Otherwise, hold the CLETOP cassette cleaner in the palm of your hand with the cassette shutter door facing up.
See Figure B-2, CLETOP Cleaner (page -7)
Rotate the cassette lever all the way down with your thumb. Do not release the lever. The lever advances the “dry” Luminex cleaning cloth inside the case and simultaneously opens the shutter. The CLETOP cassette shutter door is now open and ready for cleaning the connector.
Step 5 Lift the connector from the first slot and rotate it 90 degrees and repeat the downward motion using the second slot. Be sure the ferrule is pressed snug against the cleaning cloth while dragging the ferrule to assure the proper cleaning action.
Step 7 Wrap a Luminex cleaning cloth around the ferrule and rotate the connector housing, cleaning the outside periphery of ferrule.
Follow this by folding an unused portion of the cloth over the end of the ferrule endface and then with light pressure from the thumb, slightly drag the cloth from the center of the ferrule to the edge while rotating the connector 360 degrees. If the Luminex cleaning cloth is not available, a lint free cleanroom optic wipe can be used. The Luminex
Connector Inspection After cleaning the connector, inspect the ferrule endface to ensure that it is free from any particulate contamination using an optical fiber inspection scope of at least 200X magnification. When using an optical fiber scope (for example, the Noyes OFS 300-200X) exercise extreme caution to assure fiber being examined is de-energized.
WARNINGWhen using an optical power meter to verify the connector and fiber to be clean, take special precaution to make sure that no power is being emitted from the fiber before viewing.
Step 1 Follow the instructions in the manual provided with the Optical Fiber Scope to view the ferrule endface of the fiber under inspection.
Step 2 The visual area of the ferrule endface (ferrule and fiber) as observed by the inspection system/scope should be free of any contaminates. See Figure B-3, Acceptability Criteria for Fiber Cleaning (page -10)
Repeat the Cleaning Procedure if the fiber endface does not meet the following requirements:
Requirement: No fixed type of contamination (contaminates that remain at the same location after 3 wet-dry cleaning cycles), regardless of size, is allowed in the restricted area of the glass fiber endface.
Requirement: The restricted area is defined as ~66 microns (µm) diameter for both singlemode and multimode fibers.
Requirement: No chips, cracks or scratches are allowed near the core of the glass fiber endface.
Requirement: No large floating (loose) contaminates are allowed on the glass fiber and ceramic ferrule endface.
Step 3 After the connector has been verified to be cleaned, it should be immediately inserted into the adapter buildout of the optical component. This will assure maximum cleanliness and effectiveness of the connector.
Step 4 If the cleaned connector can not be immediately connected to a corresponding adapter, the connector ferrule must be protected with a connector dust cap. Before placing the cap on the ferrule, make sure the cap is clean. This can be accomplished by inserting a CLETOP stick cleaner (swab) of the same inside diameter as the cap (either 2.5 or 1.25 mm) and rotating the stick 360 degrees three (3) times. Following this procedure, carefully place the cap over the ferrule. When the cleaned connector is ready for assembly, it should be re-inspected for cleanliness prior to connection.
During testing and/or trouble shooting activities it may be necessary to clean the optical buildout adapter or the circuit pack connector. The following procedure is recommended
CAUTIONDo not attempt to clean ports equipped with yellow Light guide BuildOut (LBO) attenuators. Attenuators contain a thin glass lens that is extremely fragile. The LBO will be damaged if cleaned using this method.
Step 1 Using the appropriate CLETOP stick cleaner (2.5 mm for SC, ST, and FC connectors, 1.25 mm for LC connectors) dampen the stick cleaner with Ethyl alcohol using the alcohol wipe. Insert the stick cleaner into the adapter rotating the stick 360 degrees while inserting. Push/rotate stick until the stick cleaner makes contact with the connector. Apply slight pressure upon contact and rotate stick 360 degrees at least three (3) times.
Step 3 Using a dry CLETOP stick cleaner of appropriate diameter, repeat the above cleaning procedure. This procedure will clean the side walls of the adapter and the endface of the circuit pack connector.
Step 5 Verify that the fiber ferrule is clean. Repeat Step 1 through Step 3 if the fiber does not meet the requirements specified in Connector Inspection (page -9).
Purpose This appendix provides procedures for installing and removing Line Build Out units (LBOs) and fiber connectors onto input and output ports found on the Metropolis® DMXplore optical circuit packs.
Fiber Cleaning Refer to Appendix B, Fiber Cleaning for fiber cleaning information. Do not attempt to clean LBOs as they may be damaged by a cleaning attempt. Discard suspect LBOs and replace with a new unit.
General LBOs are fixed-value optical attenuators that mate into mounting blocks and provide a specific connector interface (LC, ST, FC or SC-type) for external fiber connections. The Metropolis® DMXplore optical circuit packs are equipped with LC-type connector ports designed for use with LC-type LBOs and fiber connectors. Dust caps should be applied on all LBOs when not installed in connector ports.
LC-type LBO Metropolis® DMXplore utilizes Lucent’s state-of-the-art AllWave ADVANTAGE™ Fiber Optic Attenuators. These attenuators reduce optical power from the transmitter that can result in over-saturation of the receiver, have low reflection to meet stringent system requirements, and are backward-compatible with existing transmission systems. Unique to the AllWave ADVANTAGE optical connectivity solution (OCS), the new LC™ optic attenuators are designed to provide flat spectral loss across the full spectrum, allowing the attenuators to be used in the 1300 nm, 1400 nm, and 1500 nm bands.
The LC-type LBOs are installed into the LC-type connector by aligning the alignment key with the slot in the connector port and pushing the LBO into the port until it snaps into place.
Figure C-3 LC-type LBO inserted into LC-type Connector Port
General Metropolis® DMXplore uses AllWave ADVANTAGE TM Lightguide Jumpers, part of Lucent’s AllWave ADVANTAGE Optical Connectiv-ity Solution (OCS). These jumpers contain a boot angled at 40 degrees, allowing the jumpers to dress appropriately into the fiber tray. The angled boot eliminates projection outside the front of the shelf assem-bly.
All fiber connectors should be cleaned and inspected before assembling into connector ports. Refer to Appendix B for Fiber Cleaning information. Dust caps should be applied to all fiber connectors when not installed in a connector port.
LC-type Connections LC-type fiber connectors use a snap-action, lever-tab locking method to join the fiber connector to the port connector.
Figure C-5 LC-type Fiber Connector
The LC-type fiber connector is assembled onto an LC-type connector port of a circuit pack or LC-type LBO by aligning the alignment key with the slot in the connector port and pushing the connector into the port until it snaps into place.
The LC-type fiber connector is removed from a connector port by depressing the snap-action lever to disengage the fiber connector.
Purpose This appendix provides information and the procedures used when a connector and/or pin on the Metropolis® DMXplore backplane has been bent or broken.
Description This section describes the procedures for the repair/replacement of the press-fit connector pins used on the backplane of the Metropolis®
DMXplore shelf. Trouble clearing procedures may lead you to inspect the backplane for damaged connectors.
Circuit packs are plugged into METRAL™ signal pin connectors which have been press-fit into the backplane. A plastic shroud is included with the connectors to protect the pins. The signal pin press-fit terminals in these connectors my be replaced individually if they have been damaged beyond simple repair methods.
Interface cabling to and from the Metropolis® DMXplore shelves is connected through D-Subminiature connectors which have been press-fit into the backplane. Should these connectors be damaged beyond simple repair methods, contact your next level of support for the replacement procedure.
RJ45 Jacks Interface cabling to and from the Metropolis® DMXplore shelves is connected through RJ45 connectors (jacks) which have been press-fit into the backplane. Should these jacks be damaged beyond simple repair methods, contact your next level of support for the replacement procedure.
Shelves and Backplanes The Metropolis® DMXplore has its connectors and terminal identifiers stenciled on the back surface for identification of location or position. The stenciling can only be seen when the back cover is removed.
Pins are identified by a column and row position on the backplane. D-Subminiature connectors are identified by their designation and J-number. All the METRAL™ pins used on the Metropolis® DMXplore shelves have the same tail length of 4.30mm (0.169 in.).
Table D-1 show the location and type of METRAL™ pins on the Metropolis® DMXplore backplane.
Replacement Pins Replacement pins are available. These pins are defined by the mating length extending beyond the inside of the plastic shroud and by their tail length for press-fitting into the backplane. The tail length includes a compliant press-fit section needed to achieve a gas-tight connection in four contact areas. All the METRAL™ pins used on the Metropolis®
DMXplore shelves have the same tail length of 4.30 mm (0.169 in.).
Additional replacement signal pins may be ordered in packages of 100 by the part number shown in Table D-2, Metral™ Pins.
CAUTIONThese procedures should be done with the shelf out of service and powered down to insure no further damage to the equipment or to the person doing the repair. If service cannot be removed or rerouted, contact your next level of support before proceeding.
CAUTIONProper ESD precautions must be followed.
Make sure that you have adequate space to access the backplane area and that you have good light sources so that you can see what you are doing.
Visual Examination Visually examine the connector pins to determine which pins may have been damaged and the degree of the damage. Pins that have been slightly bent may be carefully restored to their initial straight position. Examine both sides of the backplane to determine if the press-fit termination has been disturbed. These pins depend on an undisturbed interference fit between the terminal body and the plated-through hole in the backplane to create a reliable connection.
If the visual examination suggests that the connector pins are loose or are damaged beyond repair, replace the connector pin.
CAUTIONThis is a delicate procedure. Take your time to gently straighten the pin in several small steps. Large movements may damage adjacent pins.
Follow the instructions and use the tools provided in the MT370-01 Shelf Level Press-Fit Repair Kit to straighten METRALTM pins which may have been bent out of position.
If a stainless steel guide pin or keying pin has been bent out of alignment, attempts to straighten it may damage the backplane. The recommended alternative is to replace the bent pin.
D-Subminiature Pins The D-Subminiature connectors on the Metropolis® DMXplore backplane are all of the receptacle type. These connectors are designated as jacks and not as plugs. The individual connector terminals are protected somewhat by the molded plastic insert inside the connector shell. It is unlikely that these terminals would be bent in the manner that the exposed pin terminals of a plug might be bent. The damage concern for these receptacle terminals is that they may be “crushed” or otherwise distorted out of shape. Attempts to “straighten” these terminals may result in fracturing them. If a receptacle terminal has been damaged to the extent that the mating plug connector cannot be connected, then the recommended alternative is to replace the entire backplane.
Background Connector pins are designed to withstand a considerable removal force. An impact-type tool is used to generate a controlled removal force. Similarly, proper insertion of a press-fit connector pin is done with an impact-type tool to control the insertion forces and not damage adjacent pins.
Precautions Read the following Important statements before proceeding:
Important! Any press-fit connector pin may be removed and replaced one time in the Metropolis® DMXplore backplane. A second removal and replacement in the same plated-through hole may not meet the long-term reliability objectives. If a replacement is needed for a previously replaced connector pin, contact your next level of support before proceeding.
Important! Protect the surrounding area from any debris which may be generated during the pin removal and replacement.
Step 8 If the replacement is not successful, contact your next level of support.
End of Steps
Guide and Keying PinProcedure
If it becomes necessary to replace Guide or Keying Pins, contact your next level of support for tooling, replacement parts and detailed replacement procedures. The replacements will need to installed with screws and washers.
If it becomes necessary to replace either the D-Subminiature pins or connector, contact your next level of support for detailed replacement procedures.
Purpose This chapter provides the recommended checklist to follow when installing a Metropolis® DMXplore system. Use of the installation checklist is required to ensure a quality installation. All completed tasks should be checked off and those not completed should be duly noted as to the reason why. This checklist should be turned in as part of your job complete paperwork.
Fibers There are three different types of single-mode fiber used with the DMXplore system, simplex blue fiber, simplex yellow fiber, and the customer's fiber
Blue Fiber Blue fiber is made up of a single blue colored fiber equipped with LC connectors at both ends. It is referred to as Simplex LC Blue Fiber. The Blue Fibers are custom cut to length for their application. The length is given on the protection boot of the LC connector.
Yellow Fiber Simplex fibers are Yellow in color and come in six different lengths (15, 20, 25, 30, 35 and 50 feet), as well as custom lengths.
Outside Fiber Outside fiber is the fiber connecting the Customer equipment to the DMXplore . Depending on the customers specifications, these fibers may be any combination of SC, FC, or ST connectors. The length of these fibers depends on the system interface setup. This fiber is usually referred to as the Outside Bay or Plant Fiber.
Outside Bay Fiber management should be specified by the customer. It is beyond the scope of this document to specify the route or dressings that the fiber should take once it leaves the equipment bays.
Precautions
CAUTIONFiber is constructed of glass and should be treated with care. It should not be pulled or stretched. This could cause damage to the fiber or the fiber connector.
CAUTIONFiber should not be bent in a radius of less than 1-1/2”.
Step 5 Wrap the label around the boot so that the second wrap is directly on top of the first wrap. (The label will wrap around the boot approximately two times). The text is printed diagonally on the label so that it can be read when applied the correct way.
Important! Do not apply the label diagonally to the boot. The label must wrap directly on top of itself for the adhesive to work.

1+1The 1+1 protection switching architecture protects against failures of the optical transmit/receive equipment and their connecting fiber facility. One bidirectional interface (two fibers plus associated OLIUs on each end) is designated "service," and the other is designated "protection." In each direction, identical signals are transmitted on the service and protection lines ("dual-fed"). The receiving equipment monitors the incoming service and protection lines independently, and selects traffic from one line (the "active" line) based on performance criteria and technician/OS control. In 1+1 both service and protection lines could be active at the same time (service in one direction, protection in the other).
A ActiveActive identifies a 1+1 protected OC-N line which is currently selected by the receiver at either end as the payload carrying signal or a 1x1 or 1xN protected circuit pack that is currently carrying service. (See Standby).

See Non-Revertive.
RingA configuration of nodes comprised of network elements connected in a circular fashion. Under normal conditions, each node is interconnected with its neighbor and includes capacity for transmission in either direction between adjacent nodes.

UnidirectionalA protection switching mode in which the system at each end of an optical span monitors both service and protection lines and independently chooses the best signal (unless overridden by an equipment failure or by an external request, such as a forced switch or lockout). In a system that uses unidirectional line switching, both the service and protection lines may be active simultaneously, with one line carrying traffic in one direction and other line carrying traffic in the other direction. For a 1+1 protection scheme the K1 and K2 bytes in the SONET line overhead are used to convey to the far end which line the near-end receiver has chosen, so that an "active" indication may be made at the far end.
