Ubiquiti POE Help

[ScottulusMaximus]

So I've got a UniFi 6 Long-Range Access Point en-route to upgrade my network just a tad and I am super confused about POE, seems a complete mess...

AP: https://store.ui.com/collections/un...ints/products/unifi-6-long-range-access-point
POE Injector: https://store.ui.com/collections/operator-accessories/products/poe-injector-50v-60w-airfiber-poe
Router: https://store.ui.com/collections/operator-edgemax-routers/products/edgerouter-x

I got that injector because it was the only one I could find that could do 20W+ at 48V

Setup will be router>injector>AP, this shouldn't blow anything up right? Spec sheet says the AP can do "Supported Voltage Range 44 to 57VDC "

And I can't go injector>router>AP because the edgrerouter is only 24V right?

And why oh why are there so many damn POE specs, AFAIK you've got passive 24/48V and then "af" and "at" and PoE++?

No you definitely can’t go injector into router that will blow things up, but sometimes they are clever enough just to not run power.

The standard as with all of them just evolved over time as more and more powerful kit needed to run off it.

Buy the biggest one you can and you won’t have problems.

The af etc is all part of the standard, not the voltage itself. That’s a result of the standard.

Match the injector to the spec (or higher) that the AP needs and you’ll be fine.

You just need PoE+ / at which is what you got, but they really could have done a better job simply stating that on the website instead of all the irrelevant crap.

The router is irrelevant, it’s just Ethernet.
