6. Determine if the
fault is an
environmental or
configuration
fault.
Determine if the fault is an environmental fault or a
configuration fault.
If the fault listed by the show faulty command
displays a temperature or voltage fault, then the
fault is an environmental fault. Environmental faults
can be caused by faulty FRUs (power supply or fan),
or by environmental conditions such as when
computer room ambient temperature is too high, or
the server airflow is blocked. When the
environmental condition is corrected, the fault will
automatically clear.
If the fault indicates that a fan or power supply is
bad, you can perform a hot-swap of the FRU. You
can also use the fault LEDs on the server to identify
the faulty FRU (fans and power supplies).
If the FRU displayed by the show faulty
command is /SYS, the fault is a configuration
problem. /SYS indicates no faulty FRU has been
diagnosed, but there is a problem with the system
configuration.
