What is Power over Ethernet?
[[File:ZyXEL ZyAIR G-1000 and D-Link DWL-P50 20060829 2.jpg|thumb|[[Wireless LAN]] [[Wireless access point|access point]], powered by a PoE injector]] '''Power over Ethernet''' is a [[technology]] that allows to supply [[electricity]] over standard [[Ethernet]] cables. This is useful in many ways, as it allows to only have one cable to both provide the [[computer network]] and [[electricity]] to a device. It can be used for powering [[IP Phone|IP phones]], [[wireless LAN]] [[Wireless access point|access points]], network cameras, remote [[network switch]]es, [[Embedded system overview|embedded computers]], and other [[appliance]]s. In many of these cases it is often inconvenient, expensive or infeasible to supply power separately. The technology is comparable to [[plain old telephone service|POTS]] telephones. These also receive power and data through the same cable. Power over ethernet doesn't require changing the existing Ethernet cabling infrastructure. There are several general terms used to describe this feature. The terms Power over Ethernet (PoE), Power over LAN (PoL), and inline power are synonymous terms used to describe the powering of attached devices via Ethernet ports. {{tech-stub}} [[Category:Computing]]
