4.1 Error Detection

Using Front Panel LEDs

LED indicators on the front panel IPmux-1/1E indicate the operating status of the module. The LED indicators are described in Chapter 3 of this manual.

Working with the Alarm Buffer

IPmux-1/1E maintains an Event Log File. All events are time-stamped. The user can view the contents of the Event Log File via an ASCII terminal or a Telnet Session. The user can also clear the contents of the Log File.

Table 4-1presents the event types that appear on the Event Log File alphabetically, as well as the actions required to correct the event (alarm) indication.

To correct the reported problem, perform corrective actions in the given order until the problem is corrected. If the problem cannot be fixed by carrying out the listed actions, IPmux-1/1E MUST be checked by the authorized technical support personnel.
