Custom Alarms on Ethernet Ports

The 7705 SAR-A supports custom alarms on Ethernet ports without the need to deploy a
dry-contact alarm aggregator. Custom alarms can be created and assigned to any RJ-45 port;
the port must be configured for 100 Base-Tx operation with autonegotiation disabled. One
alarm input can be configured for each port with the following:
Alarm inputs must be associated with an alarm in order for them to be triggered. Alarm inputs
consist of an Ethernet LOS event caused by breaking contact loops between pins 1 and 3 or
2 and 6 on the Ethernet port. Breaking either loop will trigger the port alarm, and reconnecting
the loops will clear the alarm.
Refer to the 7705 SAR OS Interface Configuration Guide, "Configuring Auxiliary Alarm
Card, Chassis, and Ethernet Port External Alarm Parameters", for information on configuring
the alarm inputs.
You can display the status of the alarm inputs using the show>external-alarms>
input CLI command. Refer to the 7705 SAR OS Interface Configuration Guide for
examples of the alarm inputs display.
