How to clear faults
To clear faults in the Option 11C Compact system, follow the steps below:
1 Classify the fault by the indicators present (see the section “Fault
indicators” on page 460 . When there are indications of multiple faults,
clear them in the following order:
• “Clearing power faults” on page 469
• “Clearing Common Equipment faults” on page 474
• “Clearing Network faults” on page 481
• “Clearing Peripheral Equipment faults” on page 495
• “Clearing trunk faults” on page 503
• “Clearing attendant console faults” on page 510
• Telephone faults
Note: Always clear possible power faults then Common Equipment
faults before any other type of fault.
2 Go to the section for clearing the type of fault identified. There is a
section for each type of fault listed above (for example,
“Clearing
power faults” on page 469 . As closely as possible, match the problem
to a symptom listed in the section.
3 Go through the procedure for clearing each possible cause of the
problem until the fault is cleared.
4 When the fault is corrected, follow the instructions in “ “Final
maintenance procedure” on page 534 to completely restore normal
operation.
