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 is indicated by the 
two rightmost digits.
No
FRU is assigned to code 00. If only one FRU is
suspected, the other FRU code digits are filled with zeros.
See the reference page before replacing the FRU.
