FRU Codes

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.

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'
