XC1000 Service
15. Remove the four screws that secure the +12-Vdc power-supply wiring
(Figure 8-38) to the bus bars and backplane. Save them in a safe place.
16. Remove the data cables from the rear of the backplane.
17. From the front of the cabinet, remove the disk-drive-shelf backplane
(Figure 8-39). Gently rock the backplane back and forth, while pulling
it straight out to free it from the backplane connector.
18. Install the replacement disk-drive-shelf backplane.
When reinstalling the bus-terminator board, carefully align
the pins in the backplane with the connector on the
terminator board. Misalignment could damage the pins
and prevent the captive screw from being secured. This
misalignment could skew the board interface to the bus,
which would cause interference with the transfer of data
and controls signals between the CPU and the disk drives.
Caution!
19. From the rear of the cabinet, replace the drive-bus-terminator board
on the backplane. Tighten the captive screw to secure the drive-bus-
terminator board to the backplane (Figure 8-38).
20. Reattach the data cables to the rear of the backplane.
21. Reinstall the drive-fan-panel assembly and replace the 18 Phillips
screws and washers to secure the assembly to the frame.
22. Connect fan-power connector P54 to J54 on the distribution board
(Figure 8-37).
23. Connect all cables to the new backplane. To ensure accurate reattach-
ment, refer to the tags placed on each cable in step 8.
24. Replace the four screws removed in step 15 to secure the +12-Vdc
power-supply wiring to the backplane.
25. Restore all blank cover panels on the affected drive shelf.
26. Restore the XC1000 to service.
27. Return the original backplane to Octel Communications. Refer to
Appendix B for procedures to return parts to Octel.
8.7.7 Replacing the Main-Backplane Cover
Perform the following steps to replace the main-backplane cover:
1. Open the doors on the rear of the cabinet.
2. For a dual-cabinet XC1000, remove the eight Phillips screws and
washers that secure the cabinet main-backplane extender (tie plate)
to the cabinet frames, as shown in Figure 8-40.
