Troubleshoot Power Problems

  • If the server does not power on:
    • Check that AC power cords are attached firmly to the server's power supplies and to the AC sources.
    • Check the PSU Fault LED on the power supplies. If any of them are on, that power supply is in a faulted state.
    • Check that the Power/OK LED on the server front panel is steady on. If it is blinking, the server is in standby power mode. For instructions to bring it to full power mode, refer to your server's installation or administration documentation.
    • Run the HWdiag cpld vrcheck test and inspect the output for errors.
