8 Netra SPARC T4-1B Server Module Service Manual • June 2012
Possible Outcome
If this LED is not lit, check the power source and
ensure that the server module is properly
installed in the modular system chassis.
This command displays the following kinds of
faults:
• Environmental and configuration
• PSH-detected
• POST-detected
Faulty FRUs are identified in fault messages
using the FRU name.
All Oracle ILOM detected fault messages begin
with the characters SPT.
The Oracle Solaris message buffer and log files
record system events, and provide information
about faults.
• If system messages indicate a faulty device,
replace the FRU.
• For more diagnostic information, review the
Oracle VTS report. See number 4.
• If Oracle VTS reports a faulty device, replace
it.
• If Oracle VTS does not report a faulty device,
run POST. See number 5.
POST performs basic tests of the server module
components and reports faulty FRUs.
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
automatically clears.
