FRU Codes: If an error is detected by the diagnostic
tests, a four-digit FRU code is displayed. The FRU code
indicates two suspected FRUs. Replace the FRU that is
indicated by the
two leftmost digits
first; then replace the
FRU that 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 reference
page before replacing the FRU.
