Alarm Severity Classes - Juniper ACX5448-D Hardware Manual

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 red 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.
