Hmm.. I love (not) autocorrect on android... port, not portal...  But now
I'm on a real computer and have a chance to re-read the original message,
and think a bit... I think I need to change my final answer.

If these were 100 series radios I'd say "that seems rather odd that this
would cause a failure".   BUT...  I'm assuming these are 450 radios.

With the 450, there's a ethernet transformer on each pair.  To DC, this is
effectively a short.   Or since these are made with very thin wire you
could probably more accurately call it a 'fuse'.   So if you take a pair
and put say the + lead of a 24V power source on one wire in the pair, and
the return (-) on the other pair, you'd find that the wire in the
transformer would melt, and would probably do so very quickly.  This is
*exactly* the wiring that the 320/430 radios used.  In addition, there is
every possibility that the current being drawn before melting is smaller
than the amount of current needed by a real 320 or 430 radio on power on.
So, when this got plugged in, there's a good chance that you melted the
ethernet transformers.

The good news is if this is what has happened, it should be a fairly easy
fix by almost any electronic repair shop which knows how to rework surface
mount boards - just remove the magnetics and replace them.

Unless of course there was another cause.
