I bought a UAP-IW-AC Access Point and didn't realize it wouldn't turn on when one of the regular Unifi PoE Adapter was powered off and required 802.3at PoE power supply. The access point could be switched on without any problems. The manual says they don't recommend using PoE adapters, but I think they will work just fine. They say that 802.3at PoE Plus power is required to power another device through the PoE port on the access point. I have not tested this feature and have already deployed the device as my client did not need to use the network ports.
