Note: The device ID and error codes are used to indicate
in detail the 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 new
FRU might be defective or incorrectly installed.
If the problem remains after replacement of the FRUs, go
to “Undetermined Problems” on page 152.
