Caution Hijacking thread. π I need to power the Edgepoint 6 with a 24 VDC POE. Is there such a beast to do it. I have a Texas WiFi injector but pins 1236 are reversed pol from what UBNT supplies..

AF-5(not X the large full duplex radio) also will support -48VDC. AF-5X, AF-4X, AF-3X, AF-2X and AF-11FX WILL NOT ACCEPT -48VDC (positive on Earth/chassis/tower ground) AT ALL! If an βXβ radio has been powered by -48VDC with respect to case (tower ground) it will surely be damaged!

I'm getting yes, no, and maybe in even numbers. To complicate matters, I did actually power one up with -48V and it didn't explode. And that wasn't on a bench, isolated from ground. That's on a metal tower with other -48V non-isolated radios. Thanks, -Kristian On 06/27/2017 11:47 AM, Kristian Hoffmann wrote: I'm reading that as "yes, you can power it with -48VDC."
