Alarm Overview

Services Router alarms warn you about conditions that can prevent the router from operating normally.

When an alarm condition triggers an alarm, the Services Router lights the yellow (amber) ALARM LED on the front panel. When the condition is corrected, the light turns off.

NOTE: The ALARM LED on the Services Router lights yellow whether the alarm condition is major (red) or minor (yellow).

Alarm Types

The Services Router supports three types of alarms:

■Interface alarms indicate a problem in the state of the physical links on fixed or installed PIMs. To enable interface alarms, you must configure them.

■Chassis alarms indicate a failure on the router or one of its component. Chassis alarms are preset and cannot be modified.

■System alarms indicate a missing rescue configuration or software license, where valid. System alarms are preset and cannot be modified, although you can configure them to appear automatically in the J-Web or CLI display.
