Alarm Types
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.
Alarm Severity Classes
Alarms on ACX Series routers have two severity classes:
•
Major (steady red)—Indicates a critical situation on the router that has resulted from one of the following
conditions. A major alarm condition requires immediate action.
•
One or more hardware components have failed.
•
One or more hardware components have exceeded temperature thresholds.
•
An alarm condition configured on an interface has triggered a critical warning.
•
Minor (blinking red)—Indicates a noncritical condition on the router that, if left unchecked, might cause
an interruption in service or degradation in performance. A minor alarm condition requires monitoring
or maintenance.
A missing rescue configuration generates a minor system alarm.
Verifying Active Alarms
Purpose
Use the monitoring functionality to view alarm information for the ACX Series routers, including alarm
type, alarm severity, and a brief description for each active alarm on the router.
Action
•
Observe the system LED on the front panel of the router. If the router is functioning normally with no
alarms, the system LED lights green steadily.
•
Issue the show chassis alarms command to verify the status of router. As shown in the sample output,
the value Class indicates the severity of the alarm.
