I was under the impression that using two switches with an ERL wasn't a great idea (bridging the interfaces disabled hardware NAT?).
I guess another alternative would be using a non-POE switch with POE injectors. That could get kind of clunky though (I've already got three POE-powered APs). Anyone know of a simple multi port POE injector that doesn't end up being more expensive than an all-in-one option?
