Refer to Take Antistatic Measures.
A lit amber Service Required LED on a power supply indicates that a failure was detected. You can also use the Oracle ILOM show faulty command at the Oracle ILOM command-line prompt (->) to identify a power supply failure.
Alternatively, to list all known faults in the server, log into the Oracle Solaris OS and issue the fmadm faulty command, or log into the Oracle ILOM service processor from the Oracle ILOM Fault Management Shell and issue the fmadm faulty command. For more information about how to use the Oracle ILOM Fault Management Shell and supported commands, see the Oracle ILOM User's Guide for System Monitoring and Diagnostics Firmware Release 3.2.x in the Oracle Integrated Lights Out Manager (ILOM) 3.2 Documentation Library at http://www.oracle.com/goto/ilom/docs.
For instructions for disconnecting the CMA left-side connectors, refer to Remove the Cable Management Arm in Oracle Server X6-2L Installation Guide.
Caution - When disconnecting the CMA left-side connectors, be sure to use your arm to support the CMA so that it does not hang down under its own weight and stress the right-side connectors; otherwise, the CMA might be damaged. You must continue to support the CMA until you have reconnected both of the left-side connectors.
Caution - Whenever you remove a power supply, you should replace it with another power supply; otherwise, the server might overheat due to improper airflow.
