4. The PMC module has four screws. Two of the screws are secured to standoffs,
and two are attached to the front assembly of the PMC module. Remove the
two screws secured to the standoff, leaving the standoff attached to the PMC
module. Remove the two screws on the front assembly located on the side with
the standoffs. The front assembly should remain attached to the PMC hardware.
Keep the screws for reattachment.
5. Align the PMC module with the printed circuit board connectors toward the
processor board and with the fiber connectors inserted through the processor's
front panel. Align the alignment post on the processor module with the PMC
module's alignment hole.
6. Gently press the PMC module into the processor module.
7. From the back of the processor module, use the four Phillips head screws to
secure the two PMC standoff posts and PMC front assembly to the processor
module.
8. Reinstall the processor using the procedures outlined in "Processor Module" on
page 25.
The following cables connect to the CTP system:
Interface module cable—The CTP interface modules provide a 100-pin
connector for external serial interfaces connections to the CPT-1004, 1012,
2008, 2024, and 2056 systems. The quad cable ordered separately with the
system provides four standard DB-25 connectors, which are labeled P0, P1, P2,
and P3. These port numbers correspond to the port-numbering scheme
implemented in the software configuration (as detailed in CTP Software
Configuration Guide, Chapter 2, Software Configuration). Use a Revision B or later
cable when connecting it to a CTP1012, CTP2008, CTP2024, or CTP2056
system
Table 7, Table 8, Table 9, and Table 10 list the EIA530, RS-232, voice interface,
and T1 interface signals.
CAUTION:
The cable must have stress relief before you attach it to the 100-pin
connector. Connecting the cable without stress relief will damage either the
connector thumbscrews or the interface module.
