As computer systems become more sophisticated in the area of self- diagnosis, automatic execution of diagnostics and analysis routines can identify a faulty part or FRU (field replaceable unit), and automatically dispatch service personnel to make the repair. The complete list of FRU part numbers is maintained within the computer system, and the analysis routines access this data base to identify the part number of the failing FRU. The FRU list (FRU table) is generated at time of manufacture, and is representative of all FRU part numbers actually installed in the system.
