    A lit amber Fault-Service Required LED on a power supply indicates that a failure was detected. You also can 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 in to Oracle Solaris and issue the fmadm faulty command, or log in to 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, refer to the Oracle ILOM User's Guide for System Monitoring and Diagnostics Firmware Release 4.0.x in the Oracle Integrated Lights Out Manager (ILOM) 4.0 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 stop spinning when you disconnect the power cords.
  3. Gain access to the rear of the server where the faulty power supply is located.
  4. If the cable management arm (CMA) is installed, disconnect both CMA left-side connectors, and move the CMA out of the way.

    Refer to Remove the Cable Management Arm in Oracle Servers X8-2 and X8-2L Installation Guide.

    Caution

    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.

  5. Disconnect the power cord from the faulty power supply.
  6. Grasp the power supply handle and push the power supply latch to the left.

  7. Pull the power supply out of the chassis.
    Caution

    Caution  -  When you remove a power supply, replace it with another power supply; otherwise, the server might overheat due to improper airflow.

  8. Continue to Install a Power Supply.
