We are in the process of deploying an IP20C link and can confirm that they do in fact work with 48VH PoE and consume about 45 watts when fully online.

That's -48V right? Did you have to swap polarities on the pinout? (And how would you do that with power on the data lines?)

Assuming that a Ceragon IP-50E would have the same PoE pinout as the IP-20C, which has been reported to work in this thread (and in the list), I gave it a shot - and blew the fuses on the 48VH port. As it turns out after reading the Ceragon IP-50E User Manual (see page 865 for CeraOS 11.3), Ceragon expects + on pins 3/4/5/6 and - on 1/2/7/8. That will obviously cause a short if the switch provides 48VH + on 1/2/4/5 and - on 3/6/7/8 ... and so it did.

I never tried with an IP-20C but I'm wondering why it would work with 48VH if Ceragon's AC PoE Injector is the same model for IP-20C and IP-50E ... maybe with 48V instead of 48VH, but the draw would be much more than 0.75A ...

The second problem you may run into is the actually grounding. -48 should have the Positive "Grounded" to the chassis. +48 should have the Negative "Grounded" to the chassis. Some manufacturers have "Floating" Negative and Positive on their equipment where neither voltage is grounded to the chassis.

You need to do an ohms check on the DC leads and make sure that there is not a physical grounding on one of the voltage leads. Especially if you think that you can re-wire a -48 connection on a POE and hook it up to a +48 supply from another device.

As this thread helped us in figuring out the PoE situation with Ceragon MW's I will resurrect it and add some additional info for anyone that will be in the same situation as we were.

We have IP-20S MW unit which is in the same family as IP-20C. We did not use Netonix switch however we tested it out with PoE injector from Ubiquiti (POE-50-60W) which uses pins 1, 2, 4, 5 (+) and 3, 6, 7, 8 (-) which is basically the same as the switch and it works without issues.
