Remove a Power Supply
1. Prepare the system for power supply removal.
See Take Antistatic Measures.
2. Identify which power supply requires replacement.
Callout Description
2 PS1 Power supply 1
1 PS0 Power supply 0
A lit amber Fault-Service Required LED on a power supply indicates that a failure
was detected. You also can use the Oracle ILOM show faulty command at the
Oracle ILOM command-line prompt (->) to identify a power supply failure.
To list all known faults in the server, log in to the Oracle ILOM Fault Management
Shell from the Oracle ILOM service processor and issue the fmadm faulty
command. Alternatively, log in to Oracle Solaris and issue the fmadm faulty
command (Solaris root privileges required). 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 at Oracle ILOM
Documentation.
Note:
The fans of a failed power supply still might be spinning when the system
is powered on. You can remove a power supply while the fans are still
spinning.
3. Gain access to the rear of the server where the failed 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.
See Remove the Cable Management Arm for additional CMA information.
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 reconnect
both left-side connectors.
