This is normally an informational message. It
should be accompanied by other error codes
that more precisely indicate where the failure is.
Examine the service processor error log. If there
are no other power-related error codes (in the
time frame in which this code was generated) in
the service processor error log, the FRU
indicated with this error code, if any, should be
replaced.
