Remove a Power Supply

  1. Identify which power supply requires replacement.

    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 controller, log in to Oracle Solaris OS 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, 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. You can remove a power supply while the fans are still spinning.
  2. Gain access to the rear of the controller where the faulty power supply is located.
  3. If the cable management arm (CMA) is installed, disconnect both CMA left-side connectors and move the CMA out of the way.

    For instructions for disconnecting the CMA left-side connectors, refer to Oracle ZFS Storage ZS5-ES Installation Guide.


    Caution  -  When disconnecting the CMA left-side connectors, 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.

  4. Disconnect the power cord from the faulty power supply.
  5. Grasp the power supply handle and push the power supply latch to the left [1].

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

  7. Continue to Install a Power Supply.
