    Power supply 1

    1 PS0

    Power supply 0

    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.

    To list all known faults in the server, log in to the Oracle ILOM Fault Management Shell from the Oracle ILOM service processor and issue the fmadm faulty command. Alternatively, log in to Oracle Solaris and issue the fmadm faulty command (Solaris root privileges required). 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 at Oracle ILOM Documentation.

    Note:

    The fans of a failed power supply still might be spinning when the system is powered on. You can remove a power supply while the fans are still spinning.
  3. Gain access to the rear of the server where the failed 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.

    See Remove the Cable Management Arm for additional CMA information.

    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 reconnect both left-side connectors.
  5. Disconnect the power cord from the failed power supply.
  6. Grasp the power supply handle and push the power supply latch to the left.

    Open the power supply handle if the handle is folded flush. Open the velcro straps if present.

    Figure showing a power supply being removed from the chassis.
  7. Pull the power supply out of the chassis.

    Caution:

    When you remove a power supply, be sure to replace it with another power supply within 60 seconds; otherwise, the server might overheat due to improper airflow.
  8. Continue to Install a Power Supply.
