Is it possible for a gigabit switch to be PoE-powered? [closed]

I'm in need of a gigabit switch that can be powered via PoE, rather than AC power. There isn't any AC power in the area where it needs to be installed. Is this possible?

The HP ProCurve 1810-8G Switch (J9449A) is an 8-port Gigabit switch that can be powered by an upstream PoE switch. I use it in environments where I can't accommodate a power brick or need to control power from a central location (e.g. a UPS in a central server room). They're also nice when you need to use small switches because of a lack of ethernet drops in a facility.

I doubt you will find such a product. Instead, I would look for a generic PoE injector/extractor.

I think this is one of those products, but I can't get the website to load.
