8.5.3 Replacing Hot-Plug Power Supplies
Leave at least one +5-Vdc hot-plug power supply and one
+12-Vdc hot-plug power supply operating in the XC1000.
The XC1000 requires at least one +5-Vdc power supply and
one +12-Vdc power supply for a single cabinet to function,
and requires an addi5-Vdc power supply in an
additional cabinet.
Caution!
A redundant XC1000 does not need to be taken out of service to remove
power supplies equipped with the hot-plug capability; however, only one
power supply can be removed at a time. This option can be used only with
XC1000s with redundant power supplies. Power supplies are located in
both cabinets of a dual-cabinet XC1000. Perform the following steps to
replace a +5-Vdc or +12-Vdc power supply equipped with the hot-plug
capability:
1. Open the front doors of the cabinet.
2. Use a flat-head screwdriver to loosen the captive spring screw that
secures the hot-plug power supply to the front of the frame
(Figure 8-24).
After removing the power supply from the slot, there is
hazardous energy inside the space from which the power
supply was removed.
Do not
set any tools inside this
space or reach into this area.
Warning!
3. Slide the hot-plug power supply out of the slot.
4. Insert the replacement hot-plug power supply into the empty slot.
5. Make sure that the power supply is seated securely with the connec-
tors on the backplane.
6. Use a flat-head screwdriver to tighten the captive spring screw at the
front of the power supply until the power supply is secure.
7. Close the front doors on the XC1000.
8. Return the original hot-plug power supply to Octel Communications.
Use the procedure described in Appendix B.
8.5.4 Replacing the –48 Vdc Power-Control Assembly
The –48 Vdc power-control assembly is located above the +12-Vdc power
supplies, as shown in Figure 8-25. The assembly is located in both cabinets
of a dual-cabinet XC1000.
