Hi Joseph,
R710 does not have PoE out. it only has one 802.3af(PoE)/at(PoE+) in port. if you need PoE in and PoE out ports in one AP, you should consider H500 or H510s. I would recommend H510s as if you daisy chain them, you can get a gig connection between the APs. Only condition is that you need to have a PoE+ switch power up first AP.
Hope this makes sense.
Thanks
