Troubleshooting ACX5048 and ACX5096

Understanding the ACX5000 Router Alarms

The ACX5000 router support different alarm types and severity levels. Table 1 provides a list of alarm terms and definitions that may help you in monitoring the device.

Table 1: Alarm Terms and Definitions




Signal alerting you to conditions that might prevent normal operation. On the device, alarm indicators might include the LCD panel and LEDs on the device. The LCD panel (if present on the device) displays the chassis alarm message count. Blinking amber LEDs indicate yellow alarm conditions for chassis components.

Alarm condition

Failure event that triggers an alarm.

Alarm severity levels

Seriousness of the alarm. The level of severity can be either major (red) or minor (yellow).

  • Major (red)—Indicates a critical situation on the device 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 (yellow or amber)—Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance. For example, a missing rescue configuration generates a yellow system alarm.

Alarm types

Alarms include the following types:

  • Chassis alarm—Predefined alarm triggered by a physical condition on the device such as a power supply failure or excessive component temperature.

  • Interface alarm—Alarm you configure to alert you when an interface link is down. Applies to ethernet, fibre-channel, and management-ethernet interfaces. You can configure a red (major) or yellow (minor) alarm for the link-down condition, or have the condition ignored.

  • System alarm—Predefined alarm that might be triggered by a missing rescue configuration, failure to install a license for a licensed software feature, or high disk usage.

ACX5000 Router Interface Alarm Messages

Interface alarms are alarms that you configure to alert you when an interface is down.

To configure an interface link-down condition to trigger a red or yellow alarm, or to configure the link-down condition to be ignored, use the alarm statement at the [edit chassis] hierarchy level. You can specify the ethernet, fibre-channel, or management-ethernet interface type.


When red alarms or major alarms are issued on an ACX5000 router, the alarm LED glows amber instead of red.
