Troubleshoot Power Problems

If the server does not power on:

  1. Check that AC power cords are attached firmly to the server power supplies and to the AC sources.
  2. Check the power supply (PS) Fault LED on the power supplies. If the PS LED is lit, that power supply is in a faulted state.
  3. Check that the System OK LED on the server front panel is steady on, which indicates the server is in Main power mode. If it is blinking, the server is in Standby power mode.

    For instructions to bring the server to Main power mode, refer to the server Installation Guide.

  4. Check the system for faults using Oracle ILOM.
  5. Run the hwdiag cpld vr_check test and inspect the output for errors.

    This test checks the complex programmable logic device (CPLD). For information about the HWdiag utility, see Using the Oracle ILOM Diag Shell.
