Alarms for Power and Port Failure
Step 1: There are two pins on the terminal block that are used for power
failure detection. It provides a normal closed output when the
power source is active. Use this as a dry contact application to
send a signal for power failure detection.
Special note:
The relay output is normal in an open position when there is no power
to the media converter. Please do not connect any power source to
this terminal to prevent a shortage to your power supply.
