The Linksys 12 Volt Power Over Ethernet Adapter Kit lets you put your access points almost anywhere, by removing the requirement of nearby power outlets. By using the existing Category 5 Ethernet cabling to deliver power to many standard 12 volt access points and other network devices, you save the time, hassle, and expense of running AC power to the access point's installation location. The 12 Volt Power Over Ethernet Adapter Kit is a two piece set. The "Injector" sends both power and data over one Category 5 cable to your access point, wireless router or bridge. Then the tiny "Splitter", placed at the remote location, separates the network data and DC power back into two cables, and delivers them to the access point. The Injector can also be used by itself with POE-enabled network devices that accept 48 volts directly on a POE port.
