Remove a Power Supply
Callout Description
1 Power supply 0
2 Power supply 1
A lit amber Fault-Service Required LED on a power supply indicates that a failure was
detected. You can also use the Oracle ILOM
show faulty
command at the Oracle ILOM
command-line prompt (
->
) to identify a power supply failure.
Alternatively, to list all known faults in the server, log in to the Oracle Solaris OS and issue
the
fmadm faulty
command, or log in to the Oracle ILOM service processor from the Oracle
ILOM Fault Management Shell and issue the
fmadm faulty
command. For more information
about how to use the Oracle ILOM Fault Management Shell and supported commands, refer to
the Oracle ILOM User's Guide for System Monitoring and Diagnostics Firmware Release 4.0.x
in the Oracle Integrated Lights Out Manager (ILOM) 4.0 Documentation Library at
http://
www.oracle.com/goto/ilom/docs
.
Note -
The fans of a failed power supply might still be spinning when the system is powered on.
The fans will stop spinning when you disconnect the power cords.
3. Gain access to the rear of the server where the faulty power supply is located.
4. If the cable management arm (CMA) is installed, disconnect both CMA left-side
connectors and move the CMA out of the way.
Refer to “Remove the Cable Management Arm” in Oracle Servers X7-2 and X7-2L Installation
Guide .
Caution -
When disconnecting the CMA left-side connectors, be sure to use your arm to
support the CMA so that it does not hang down under its own weight and stress the right-side
connectors; otherwise, the CMA might be damaged. You must continue to support the CMA
until you have reconnected both of the left-side connectors.
5.
Disconnect the power cord from the faulty power supply.
