1. Prepare the system for power supply removal.

   Refer to Take Antistatic Measures.

2. Identify which power supply requires replacement.
   

   Figure Legend Description 1 Power supply 0 2 Power supply 1

   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.

   Note -  The fans of a failed power supply might still be spinning when the system is powered on. The fans will stop spinning when you disconnect the power cords.

3. Gain access to the rear of the storage server where the faulty power supply is located.
4. Disconnect both cable management arm (CMA) left-side connectors and move the CMA out of the way.

   For instructions for disconnecting the CMA left-side connectors, refer to Remove the Cable Management Arm in Oracle Exadata Storage Server X5-2 Extreme Flash 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.
