Aux port for backup 5GHz link

Is it possible to use AUX port for backup 5GHz link on V3000.
Since the F425 can be powered directly from the port, that solution would be great.
I tried to connect 5GHz dish with the OpenR option turned on but it doesn’t work, nothing happen when 60GHz link is lost.

Working on a similar issue but not using Open/R - just trying to use the AUX port for a backup connection: Backup link using AUX port creates odd loop
