UAP-AC-Pro compatible with older PoE Injectors from Square AP AC?

I'm going to be swapping out some older Square AP AC access points with the newer UAP-AC-Pro model at a job site, and I was curious if the PoE injectors from the old Square AP AC model would also power the new UAP-AC-Pro model. Do I need to purchase replacemet PoE Injectors or will the old ones still work?

Hello @RobbieH,

 

The UAP AC ( v2 ) comes with a 48v 0.5A PoE Injector...

The UAP AC PRO comes with a 48v 0.5A PoE Injector...

So it should work.

Two issues -

The old ones are 24v, the new ones are 48v.

The old power injectors are 100mbps, the new ones are gigabit.

 

I think this is correct, I never used the square one, but I have one of the very next gen, the round with green light.

Hello @hoveeman,

 

The PoE injector should work fine on the new UAP AC PRO.

I would still check the back of the PoE injector for the specs..

Wow so they were using different injectors across models even all the way back then?

Thanks for the help! I will double check the specs on the back of the power supplies to make sure.
