AF5x on 48 HV
Ubiquiti is now saying that AF-5X can accept 48v. Should we use them on the normal 48v ports or the 48HV?

READ THIS POST viewtopic.php?f=6&t=1178
airFIBER 24 and airFIBER 5 require 48VH
If you power and airFIBER 24 or airFIBER 5 with 48V you will blow out your Ethernet Transformer on the switch and maybe the airFIBER and this tye of damage is not covered under warranty.
The new airFIBER X can use 24V on cable runs around 200' and 24VH for longer runs

Yes I know about af24 and af5. I'm talking about the airfiber x series. The post is in the edgemax alpha forum by UBNT-Gary.

I have no idea about that post (did not see it)??
I would be very careful trying that!!!!!
But why use a 48V port when you know the 24V port works fine SAFELY?

Re: AF5x on 48 HV
"IF" the device can handle 48V it could require less watts from the bottom but would cause more heat in the airFIBER X unit as it would be required to step down more to 3.3V and 1.5V to drive the board.
Not sure what UBNT is thinking as this will even further muddy the POE waters with their POE requirements across devices.
That is great if all will accept both and not just "NEW" units (boy that would be a mess).
I thought it was ODD that airFIBER X was 24V to start with but I am still leary to try this. I think I will let others cut the path on this one.

Re: AF5x on 48 HV
Here's from the post:
"You are both correct, X radios will accept 48VDC. We have not updated our documentation to reflect this because the first 100 units that shipped can't tolerate 48V so we didn't want to call attention to it yet. I will ask @ubnt-greg to publish the list of the first 100 "X" S/N's so users can figure out if their radio needs to stay with 24VDC..."

Here we go:
