Servicing CRUs That Do Not Require Server Power-Off 57
▼ Remove a Power Supply
1. Identify which power supply requires replacement.
A lit amber 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 prompt (->) to identify a power supply failure.
Alternatively, to list all known faults in the server, log into the Oracle Solaris OS
and issue the fmadm faulty command, or log into the Oracle ILOM service
processor from the Oracle ILOM Fault Management Shell and issue the fmadm
faulty command.
Note – The fans of a failed power supply might still be spinning when the system is
powered on. You can remove a power supply while the fans are still spinning.
2. Gain access to the rear of the server where the faulty power supply is located.
3. If the cable management arm (CMA) is installed, disconnect both CMA left-side
connectors and move the CMA out of the way.
For instructions for disconnecting the CMA left-side connectors, see the Sun Server
X4-2 Installation Guide, “Remove the Second-Generation Cable Management Arm”
on page 64 or Sun Server X4-2 Installation Guide, “Install the First-Generation Cable
Management Arm” on page 69 as applicable.
