Troubleshooting
The fault indications identified in this chapter provide a guide for isolating
failures to a Field Replaceable Unit (FRU). The service technician should
perform troubleshooting whenever a failure occurs during normal operation
that cannot be resolved by the Operations and Maintenance Center (OMC).
Some indications list several possible failures along with corresponding
corrective actions. If a failure is isolated to the FRU level, the suspected
module should be replaced with a new one. This restores the system to
normal operation as quickly as possible.
Suspected FRUs should be shipped to a Motorola repair depot for repair.
