Troubleshooting the ACX5448, ACX5448-D,and ACX5448-M Router
Alarm Types and Severity Classes on ACX Series Routers
Before monitoring the alarms on the router, become familiar with the terms defined in Table 1.
Table 1: Alarm Terms
Signal alerting you to conditions that might prevent normal operation. On a router, the alarm signal is the red system LED that is lit on the front of the chassis.
Failure event that triggers an alarm.
Seriousness of the alarm. The level of severity can be either major (steady red) or minor (blinking red).
Predefined alarm triggered by a physical condition on the router, such as a power failure, excessive component temperature, or media failure.
Predefined alarm triggered by a missing rescue configuration or failure to install a license for a licensed software feature.
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.
