A lit amber Fault-Service Required LED on a power supply indicates that a
failure was detected. You can also use the Oracle ILOM showfaulty 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 (Solaris root privileges required), or log in to the Oracle ILOM Fault
Management Shell from the Oracle ILOM service processor 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 5.0.x
in the Oracle Integrated Lights Out Manager (ILOM) 5.1 documentation at
Servers Documentation - Systems Management
.
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.
Gain access to the rear of the server where the failed power supply is
located.
If the cable management arm (CMA) is installed, disconnect both CMA left-side
connectors and move the CMA out of the way.
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.
Disconnect the power cord from the failed power supply.
Grasp the power supply handle and push the power supply latch to the
left.
Pull the power supply out of the chassis.
Caution:
Whenever you
remove a power supply, you should replace it with another power supply; otherwise,
the server might overheat due to improper airflow.
