Table 30: Alarm Terms

Term Definition
Alarm Signal alerting you to conditions that might prevent normal operation.
On a router, the alarm signal is the red system LED lit on the front of
the chassis.
Alarm condition Failure event that triggers an alarm.
Alarm severity Seriousness of the alarm. The level of severity can be either major
(steady red) or minor (blinking red).
Chassis alarm Predefined alarm triggered by a physical condition on the router, such
as a power failure, excessive component temperature, or media failure.
System alarm Predefined alarm triggered by a missing rescue configuration or failure
to install a license for a licensed software feature.
The router supports these alarms:
Chassis alarms indicate a failure on the router or one of its components. Chassis alarms
are preset and cannot be modified.
System alarms indicate a missing rescue configuration. System alarms are preset and
cannot be modified, although you can configure them to appear automatically in the
J-Web interface display or CLI display.
