as a power failure, excessive component temperature, or media failure.
system alarm Predefined alarm triggered by a missing rescue configuration or failure

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.
Alarms on ACX Series routers have two severity classes:
Major (steady red)—Indicates a critical situation on the router that has resulted from
