How to clear faults
Fault clearing process
When a fault must be cleared in the Option 11C Compact, follow these steps:
•
Observe and record all fault indicators.
•
System messages, visual fault indicators and user reports identify many
problems. If the indicators are not current or seem incomplete, you may
need to print the History File for previous messages, you may need to
initialize the system for information on the current status, or both.
•
Look up all system messages in the Option 11C Compact Software
Guide.
The interpretation of the message may identify faulty equipment and
indicate what action to take to clear the problem. If you cannot clear the
fault through information in the Option 11C Compact Software Guide,
follow the process in this section to isolate and clear the fault.
•
Try to enable or test disabled equipment.
•
You may be able to hardware re-enable circuit cards by unseating then
reinstalling them. You may be able to software re-enable cards by
disabling then re-enabling them. When the cause of a fault is not clearly
evident, a software test may help you identify the problem.
•
Replace equipment as necessary.
