COMM lost way to many times

On the other hand, more than half the robots I checked had loose terminals either on the battery or the main circuit breaker. All of the "lost communication" events I followed up on at both of the events I worked at were associated with a faulty power connection. All.

(I'm counting only ones where there was actually a loss of communication, not the few the drivers called "lost comm" but where the problem was that robot code crashed or a joystick came disconnected or the Driver Station was being interfered with by a software update process.)

I'm not familiar enough with PoE to be comfortable without some details. I sure don't want to fry a radio. With a quick search I haven't found out the best way to wire a PoE for this this radio. I assume you can use the 12 v port on the VRM into a spliced ethernet cable but what pins are used and which port does it go into in the router. I apologize if this has already been discussed. I didn't see it in my searching, but might have been looking for the wrong things.
