   About Power over Ethernet Technology

   PoE is a technology for wired Ethernet, the most widely installed
local area network technology in use today. PoE allows the electrical
power necessary for the operation of each end-device to be carried by
data cables rather than by separate power cords. It minimizes the
number of wires that must be used in order to install the network,
resulting in lower cost, less downtime, easier maintenance and greater
installation flexibility.
