Well, if you only need 4 ports, the ER-X would be fine. If you need more than 4, it's kind of a wash (though the erx is less expensive ![Man Wink]( "Man Wink")
).
1. Yes
2. No, ac-lite / ac-lr / ac-pro are gen2 units, the original ac (square) is gen1. ZHO isn't something you need either.
3. Yup
4. Yup
5. Sort of. The ER-X can be powered by poe, and if powered by poe, can power one other 24v device. If you have more than one AP (and don't want injectors all over the place) , $20 will get you an ER-X-SFP, which has 24v poe on all ports.
