Server Alarms - Avaya Support

Communication Manager Maintenance Object Repair Procedures
After cabling changes are made and verified, power must be restored to the port network.
Circuit packs in carriers that are not part of the shortened bus are not inserted. As a result,
these circuit packs are alarmed. Ignore these alarms for now. All alarms should be resolved
when the cabinet is restored to its original configuration.
Procedure 2 is organized into two parts:
● Part 1 attempts to clear the Serial Bus fault by replacing all the bus cabling and terminators
within a port-network.
● Part 2 attempts to isolate the fault to a particular carrier by extending the Serial Bus from
the A carrier to additional carriers one at a time.
Refer to the repair procedure steps given for the Serial Bus Status Test (#1531)
