Troubleshooting the ACX7348 Router
Troubleshooting ACX7348 routers includes recognizing alarm types and alarm severity classes and resolving the error conditions that trigger alarms.
Alarm Types and Severity Classes on ACX7348 Routers
Before monitoring the alarms on the router, become familiar with the terms defined in Table 1.
Term | Definition |
|---|---|
Alarm | Signal that alerts you to conditions that might prevent normal operation. On a router, the alarm signal is the ALM LED that is lit on the front of the chassis. |
Alarm condition | Failure event that triggers an alarm. |
Alarm severity | Seriousness of the alarm. The level of severity can be either major (steady red) or minor (steady amber). |
Chassis alarm | Predefined alarm that is triggered by a physical condition on the router, such as a power failure, excessive component temperature, or media failure. |
System alarm | Predefined alarm that is triggered by a missing rescue configuration or failure to install a license for a licensed software feature. |
Alarm Types
The ACX7348 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 ACX7348 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 of the fans has failed.
A power supply module (PSM) is not connected or a PSM has failed.
One or more hardware components have exceeded temperature thresholds.
An alarm condition that is configured on an interface has triggered a critical warning.
Minor (steady amber)—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.
