Power Supply Failure

Removing the 650-Watt Redundant Power Supply

007-5843-002
If the power supply unit experiences a failure, the system will shut down if it is a 450-Watt
"non-redundant" supply and you will need to replace the power supply unit to return the
C1110-RP6 to operating status. Note that the 450-Watt unit has an On/Off rocker switch; make
sure the switch has not accidentally been turned off before replacing it.
If the power supply is 650-Watt redundant supply that experiences a failure - the server can
continue to operate until a replacement is available. Shutting down the server during replacement
of the "redundant" unit is optional.
Replacement power supply units can be obtained directly from your SGI sales or service
representative or third-party support provider.
If the power supply has failed, the LED located on the front of the power supply should be off
(unlit). Be sure the system power cord is fully plugged in to a power distribution unit that is turned
on before replacing the supply.
Use the following steps to remove a failed 650-Watt power supply from the system:
1. Unplug the AC power cord from the failed side of the redundant power supply system.
Caution: The power supply may be hot if the system has been running - make sure the supply
has at least 5 minutes to cool down.
2. Push the release tab on the front of the power supply inward. See Figure 4-6 on page 36.
3. Pull outward on the power supply handle and the unit should disengage from the internal
connector.
4. Extract the supply from the chassis by pulling it outward. Handle it with caution as the unit
may still be hot.
5. Follow the instructions in "Installing a New 650-Watt Redundant Power Supply" on
page 37.
