Troubleshooting the ACX7024 Router
Alarm Types and Severity Classes on ACX7024 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 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 ACX7024 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.
-
If any fan has failed.
-
If any power supply module (PSM) is not connected or if 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.
