You can raise a dry contact output alarm to any external entity that is connected
to the 4Motion unit via the 25-pin micro D-Type jack on the NPU front panel. To
raise a dry contact output alarm, run the following command:
npu(config)# dry-contact OUT <alarm_num (1-3)> alarm <alarm name >
In this command, the alarm_num parameter maps to a specific pin of the micro
D-Type ALRM-IN/OUT connector. The following table lists the pin numbers of the
25-pin micro D-Type ALRM-IN/OUT connector corresponding to the alarm
number you are configuring:
In this table, N.C denotes Not Closed, and N.O denotes Not Open.
