Configuring Chassis Alarm Output
The ACX Series router alarm contact port—labeled ALARM on the front panel—allows
you to manage sensors and external devices connected to the router in remote unstaffed
facilities. You can configure up to two alarm output relay ports (0 and 1) to operate as
normally open or normally closed, and to trigger an alarm when the system temperature
goes to the red alarm status and when an alarm input port is triggered.
NOTE: Ports 2 and 3 are not configured. They are used to indicate system
major and minor alarms and are normally open. When a condition triggers
an alarm, an alarm message is displayed, and the corresponding LED turns
on.
To configure an output alarm:
1. Configure the output port:
[edit chassis alarm relay output port port-number]
For example, to configure output port zero (0):
user@host# edit chassis alarm relay output port 0
2. Configure the trigger to set off the alarm:
