8.5.1 Replacing the Power-Distribution Assembly
The power-distribution shelf is located above the logic bay in cabinet 1.
Facing the rear of the cabinet, the power-input cables and output cable
harness enter and exit the right side of the power-distribution shelf. It is
the policy of Octel Communications to replace the entire power-distribution
assembly in the event of any component failure.
This replacement procedure requires two people. Perform the following
steps to replace the power-distribution assembly:
1. Use the procedure in section 8.2 to take the XC1000 out of service.
2. Turn off power to the XC1000 by switching the main-power circuit
breaker to the OFF position (
0
).
The capacitor located on the power-distribution shelf
stores a hazardous charge. Wait 5 minutes for the capaci-
tor to discharge before touching it.
Danger!
3. Wait 5 minutes before proceeding, to allow the capacitor on the
power-distribution shelf to discharge.
4. Remove the four screws that secure the inspection panel to the back
of the shelf, as shown in Figure 8-19. Remove the inspection panel.
