its internal connector does not have

shutdown, due to a failed power
supply. The redundancy allows
the server to continue to operate
if one of the power supplies fails.
However, when a server SMOD is
being powered by a single power
supply, the redundancy no longer
exists, and the risk for downtime or
an unexpected shutdown increases.
When installing a power supply,
ensure that it is fully seated and
engaged with its connector inside
the drive bay. A properly installed
power supply has a lit green AC OK
indicator.
Troubleshooting Using Diagnostic Tools
The server and its accompanying software and firmware contain diagnostic tools and features
that can help you isolate component problems, monitor the status of a functioning system,
and exercise one or more subsystems to disclose more subtle or intermittent hardware-
related problems. Diagnostic tools range in complexity from a comprehensive validation test
suite (Oracle VTS) to a chronological event log (Oracle ILOM System Log). Tools include
standalone software packages, firmware-based tests, and hardware-based LED status indicators.
Each diagnostic tool has its own specific strength and application. Review the tools listed in
this section and determine which tool might be best to use for your situation. Once you've
determined the tool to use, you can access it locally, while at the server, or remotely.
Diagnostic Tools
The following table summarizes server diagnostic tools and identifies where you can find more
information about diagnostic tools.
