Resulting Action
The Power OK LED is located on the front and rear
of the chassis.
The AC Present LED is located on the rear of the
server on each power supply.
If these LEDs are not on, check the power source
and power connections to the server.
The show faulty command displays the following
kinds of faults:
• Environmental faults
• External I/O Expansion Unit faults
• Solaris Predictive Self-Healing (PSH) detected
faults
• POST-detected faults
Faulty FRUs are identified in fault messages using
the FRU name.
Note - If the ILOM show faulty output includes
an error string such as Ext sensor or Ext FRU, it
indicates a fault in the External I/O Expansion Unit.
The Solaris log files and the ILOM system event log
record system events, and provide information
about faults.
• Browse the ILOM system event log for major or
critical events. Some problems are logged in the
event log but not added to the show faulty list
• If system messages indicate a faulty device,
replace the FRU.
• To obtain more diagnostic information, go to
Action No. 4
SunVTS is an application you can run to exercise
and diagnose FRUs. To run SunVTS, the server must
be running the Solaris OS.
• If SunVTS reports a faulty device, replace the
FRU.
• If SunVTS does not report a faulty device, go to
Action No. 5.
