Running the Diagnostics
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 00. See the reference page before
replacing the FRU.
