Note: The device ID and error codes are used to indicate
the detail portion of the FRU that caused the error.
If replacing a FRU does not correct a problem, see
the Device ID or error code from the previous
failure. If they have changed, the cause might be
that the new FRU is defective or that the FRU was
incorrectly installed.
If the problem remains after replacement of the FRUs, go
to "Undetermined Problems" on page 419.
