Fault Diagnosis

4.2Diagnosis from System Messages

The flow of works from diagnosis of system message up to discovery of the cause of the fault is shown in Figure 6-3.

Diagnosis from System Message

Identification of Faulty Card, Faulty Equipment

Check the cause of the fault by diagnosing the printed out system messages.

If, during the diagnosis, an alarm such as circuit card initialization, etc., has been indicat- ed, reset (clear) the alarm indication by depressing ALM RST key on the frame-top alarm panel.

If, as a result of the diagnosis, the fault is a temporary one, cancel all alarm indications and release system messages stored in the memory by RALM command and keep watching the system operations thereafter.
