Troubleshoot Power Problems
If the server does not power on:
Check that AC power cords are attached firmly to the server power supplies
and to the AC sources.
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.
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.
Check the system for faults using Oracle ILOM.
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.
