Integral board and module for power over LAN
First Claim
1. Apparatus for supplying power to communication devices operating within a Local Area Network (LAN) over LAN cabling, the communication devices including one or more powered devices adapted to receive power over the LAN cabling, the apparatus comprising:
- a power supply which is adapted to receive power from an unregulated source and to provide therefrom regulated power;
power distribution and control circuitry, which is adapted to identify the powered devices on the LAN, to receive the regulated power and to generate therefrom respective output voltages for supply to the powered devices; and
a chassis which retains the power supply and the power distribution and control circuitry as a single module.
