Power over Ethernet (PoE)?

[ravenvii]

I was curious about the PoE (Power over Ethernet) feature of the AirPort Extreme. All I know is that it enables the AirPort to receive power through ethernet. But how exactly does that work? And how do you get power through ethernet?

You need a special box at the other end of the connection that injects power. You can't do it with standard ethernet connection.

You can see some switches here that can supply power over ethernet.

the PoE editions of Airport Extreme Base stations is only available through the institutional store(i think). It is a function so that you can string a bunch of APX stations along without needing an AC power input.

Not really functional for consumer use. Although I'd love to just be able to plug an ethernet cable into my MacBook and not have to plug in my AC adapter.

Ah, interesting. My AirPort Extreme does have capability for PoE. It was bought two years ago. Not anything I need or would use, I was just wondering what exactly it is. Thanks guys.
