Flowchart item 6.
Check if the fault is
environmental.
Determine if the fault is an environmental fault or a
configuration fault.
If the fault listed by the
show faulty
command
displays a temperature or voltage fault, then the fault is
an environmental fault. Environmental faults can be
caused by faulty FRUs, or by environmental conditions
such as when computer room ambient temperature is
too high, or airflow is blocked. When the environmental
condition is corrected, the fault will automatically clear.
For additional information on a reported fault, including
possible corrective action, go to this web site:

where message-ID is the message contained in the fault
message.

Determine if the
fault was detected
by PSH.
If the fault message does not begin with the characters
“SPT”, the fault was detected by the PSH feature.

After the FRU is replaced, perform the procedure to

Flowchart item 8.
Determine if the
fault was detected
by POST.
POST performs basic tests of the server module
components and reports faulty FRUs. When POST
detects a faulty FRU, POST logs the fault and if possible,
takes the FRU offline. POST detected FRUs display the
following text in the fault message:
Forced fail
reason
where reason is the name of the power-on routine that
detected the failure.

Contact technical
support.
The majority of hardware faults are detected by the
server module’s diagnostics. In rare cases a problem
might require additional troubleshooting. If you are
unable to determine the cause of the problem, contact
your service representative for support. • “Support and Accessibility”
