Hello,
In a few days I’m going to receive a “gift”, an AP Ubiquiti AC Pro. I’ve seen in the datasheet that it supports PoE passive 48v, 9W and 0.5A.
Is it possible to use the PoE:out of a hAP ax² to power the AP?
Best regards!! 
Albert.
No. The hAPax2 “dual use” PoE port is passive, but it does support 48V input.
Hello Amm0,
Thank you very much for your response, in that case I will buy a PoE injector.
Best regards!!
