I'm not the one to ask on this, but I'd think if you put the wrong power
polarity (or the screwy twisted pair power) into a 100 or 450 radio, my
thinking is the ethernet/PoE transformer in the radios might be damaged.
But again, this probably should've been seen as a short or over-current
by the SyncInjector and the port power should've tripped, possibly
saving the radios. But you never know until you check them out.
Good luck. I hope it wasn't a total loss.

I haven't taken them off the tower yet. Brand new tower. AP's havent been
even used yet. I am taking them down tomorrow and checking them out. But the
LED on the power supply stays on. I did try that today. I just dont know if
they radios actually power up and have bad ethernet ports or if they are
completely dead. Either way its a 200' climb to replace radios that have never
even been in use and likely never will be. Oh well I guess it is supposed to
be a nice day. I would rather be at 200' than anywhere else anyway..

The 320 and 430 have that crazy +/-/+/- PoE pinout scheme. So that's
what the 320/430 SyncInjector puts out. If you had PMP100 or 450 radios
plugged into that, I would think the overcurrent protection in the
injector would've kicked in, but who knows.
If you try to power them up with a regular AC/DC Canopy PoE, does the
power LED light up on them? I'm betting not and they'll have to be repaired.

So we accidentally put sync injectors on to a din rail today that were for the
320/430 radios. Oops
Both of the injectors were powered by a 24 V 10 amp power supply
All of the radios that were plugged into those injectors no longer appear to
boot up which wouldn't surprise me if there had been a 56 V power supply or 48
V power supply powering them. However since they were powered by a 24 V power
supply how could that have damaged the radios?
