Chapter 1: Communication Manager
Maintenance Object Repair
Procedures
This chapter provides information for troubleshooting and repairing maintenance objects.
Note:
Note: This chapter does not contain maintenance objects for the Avaya Wireless
Business System or messaging systems. Refer to the documentation that
accompanies these products for this information.
Each identifiable part in the system is considered a maintenance object (MO). A maintenance
object can be:
● An individual circuit pack or media module
● A hardware component that is part of a circuit pack or media module
● Any software process
● Significant events
● Environmental controls
● A cabinet
Each maintenance object has its own unique set of tests, error codes, and recovery strategy.
Maintenance software logs inline errors reported by circuit packs and media modules, runs tests
for error diagnosis and recovery, and raises and clears alarms.
“Maintenance names” are recorded in the Error and Alarm logs. Individual copies of an MO are
assigned an address that defines the MO’s physical location in the system when applicable.
These locations display as the port field in the Alarm and Error logs and as output of commands
such as test board (see Figure 1: Display of test board).
