1 1. Introduction Power-over-Ethernet (PoE) eliminates the need to run 110/220 VAC power to other devices on a wired LAN. Using Power-over-Ether net system installers need to run only a single CAT5 Ethernet cable that carries both power and data to each de vice. This allows greater flexibil ity in the locating of network dev ices and significantly [...]
