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.
