Resulting Action
The Power OK LED is located on the front and rear
of the chassis.
The AC OK 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 showfaults command displays the following
kinds of faults:
• Environmental faults
• Solaris Predictive Self-Healing (PSH) detected
faults
• POST detected faults
Faulty FRUs are identified in fault messages using
the FRU name. For a list of FRU names, see
Appendix A.
The Solaris message buffer and log files record
system events and provide information about
faults.
• 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.
