FRU Codes
If an error is detected by the diagnostics tests, a
four-digit
FRU code is displayed, along with an error code. The
FRU code indicates two suspected FRUs. Replace the
FRU that is indicated by the
two leftmost digits
first, and
then replace the FRU indicated by the
two rightmost digits
.
No FRU is assigned to code 00. If only one FRU is
suspected, the other FRU code is filled with zeros. See
the referenced page before replacing the FRU.
