Use test eda-external-device-alrm to perform hardware diagnostic tests on the alarm port for either an individual device, or every external device.

If all is entered, test eda-external-device-alrm performs a hardware diagnostic test on every administered external device’s alarm port. If an administered external device’s alarm port is entered, this command performs a hardware diagnostic test on that port.

The test passes if the external device is not reporting an external device alarm and fails if the external device is reporting an external device alarm. If the technician specifies a port, it must be administered as an external device’s alarm port either on a maintenance board or on an analog line board.
