According to Netgear's PowerLine FAQ (link), they do not offer any Powerline adapters with PoE support. Do a Google search for powerline poe and you will find other vendors. It seems that your use case is very common!
I am in search of a powerline unit that can pass power over ethernet but not have a seperate power cable. I need a unit that can take power and pass it on the same ethernet cable. It is for a PoE camera. All the adapters I have found have a seperate DC output. So I assume then that the power gets seperated. Anybody know if the powerline units can pass power or of an adapter that passes PoE straight thru?
