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. -forrest On Thu, Apr 23, 2015 at 9:58 PM, Forrest Christian (List Account) < [email protected]> wrote: > Due to the odd wiring the radios probably shorted out the overcurrent > protection in the injectors, turning off the portal and I'd not be > surprised if the radios are just fine.
