Alarm Types; Alarm Severity Classes; Verifying Active Alarms - Juniper ACX2000 Hardware Manual

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.
