Remove the rear center-section cover of tower #2 and connect the pair of UCN drop

cables for this redundant NIM to the NIM MODEM card in a similar manner to that

used to connect the first pair to the primary NIM in tower #1 (subsection 2.7.8).  BE

SURE “A” AND “B” CABLES CONNECT RESPECTIVELY TO THE “A” AND “B”

CONNECTORS  on the board or card without cross-connection.  There is a separate

ground wire that connects the building ground to each UCN tap.

2. Firmly reinstall the card.  Route the UCN cables from the card out of the cabinet

without making sharp bends or kinks in the cables.  Using a cable-tie (51190879-001)

on each cable, fasten the UCN cables to their strain-relief clamps (marked UCN CBL in

Figure 2-5) on the lower transition panel of Tower #2.

3. The NIM MODEM card in this redundant NIM has been factory-pinned to UCN

address #2.  You will verify this address in Section 4 of this manual.  Consult UCN

manuals listed in subsection 1.5 for installation and pinning of the Advanced Process

Manager that this NIM “talks” to.  Pinning for the odd address for the first PMM yields

the even address for the redundant PMM automatically

Optional Computer Gateway CLI I/O

The optional computer gateway adds one or two connections to a host computer.

1. Remove the rear center-section cover of tower #2 and connect the computer cable

(503790-xxx) to JA of the CLI I/O board (see Figure 2-16).  Use a small screwdriver to

tighten the screws (2) on the connector.

30732052‑001

The tab number (-xxx) in the cable drawing number refers to its length in meters.  The

maximum cable length is 305 meters (1000 feet)

If the host computer is running in a redundant mode, an additional cable must be

connected from the computer to JB of the CLI I/O board (see Figure 2-16).  Use a small

screwdriver to tighten the screws (2) on the connector.

3. Using a cable-tie (51190879-001) on each cable, fasten the cables to their strain-relief

clamps (marked OPTIONS in Figure 2-7) on the lower transition panel

The optional computer gateway adds one or two connections to a host computer.

Figure2-17 and Figure 2-18 show the physical characteristics of the Computer Gateway

I/O board designed to follow the EMC Directive.  The board design remains the same as the

old version.  A bulkhead face plate is added to the PWA and supports the two D-type

connectors.  The cables are changed to braid over foil shield with 360 degree metalized

plastic back-shells
