1. Display the Error and Alarm Logs for the circuit pack via the display errors
and display alarms commands.
2. If there are errors for the circuit pack, refer to the appropriate maintenance
documentation in Chapter 10, ‘‘Maintenance Object Repair Procedures’’,
and follow the recommended maintenance procedure to resolve the errors.
Note that some of these procedures may refer to PKT-BUS maintenance
as the cause of the fault; if so, implement these Packet Bus Fault
Correction procedures at that point.
3. After implementing the repair procedure for the circuit pack (and regardless
of whether this procedure succeeds or fails), determine if the Packet Bus
fault is still present.
4. If the Packet Bus fault is still present, implement Procedure 1 for the next
circuit pack.
5. If there are no more circuit packs in the list, go to Procedure 2.
6. If the Packet Bus fault has been resolved, the procedures are completed.
