Fault IsolationTL-130200-1001
5.0 Maintenance personnel can determine the source of most
system failures based on built-in software fault reporting. Fault
messages on the system terminal are used with standard
troubleshooting procedures to isolate problems with specific
components. Replacement or repairs can then be made. Many
times this will only involve card replacement.
5.1 A comprehensive set of troubleshooting procedures indexed
by fault codes follows. The technician should first examine all
faults reported on terminal printouts and/or the fault log.
5.2 The procedures and flowcharts which follow list
specifications and steps which should be taken for each of the
system’s fault codes.
5.2.1 Always check the Attendant Console power source for
proper voltages before replacement if a failure occurs. System
-related console troubleshooting is contained in TL-1301
