I don't have access to the MAC ID of my AP. (I'm in a remote location)
How can I check if it supports 802.3af ?
All I know I bought it in Dec 2016. and the board revision number is 27.
Turn on POE+ on the switch and see if it comes back up.
The datecode can still be older depending on where you bought it.

My AP supports it.
OMG it took me forever to find this article from Ubiquiti.
The UAP-AC-LR/LITE was revised after date code 1638/board revision 17 and subsequent units support 802.3af in addition to 24V passive. Board Revision information can be found in the UniFi Network Controller within the properties panel of each UAP in the Details > Overview section.
