High power architecture for power over Ethernet
First Claim
1. A local area network adapted to supply power to powered devices over a plurality of paths thus supplying high power, the local area network comprising:
- at least one powered device;
a hub adapted for communicating data to and from said at least one powered device;
communication cabling connecting said at least one powered device to said hub, said communication cabling comprising a first set of wire pairs utilized for communicating data between said at least one powered device and said hub and a second set of wire pairs;
a first power output adapted to supply a first power over at least a portion of said first set of wire pairs;
a second power output adapted to supply a second power over at least a portion of said second set of wire pairs; and
a combiner operable to receive said first power over said at least a portion of said first set of wire pairs and to receive said second power over said at least a portion of said second set of wire pairs, said combiner being further operable to combine said received first power and said received second power to a combined high power output.

Abstract
A combiner for use with a powered device having high power needs, the combiner comprising: a first power input adapted to receive a first power signal over a first set of wire pairs utilized to carry communication data; a second power input adapted to receive a second power signal over a second set of wire pairs, wherein the first power signal is combined with the second power signal to produce a combined high power signal; and a control circuit operable to sense the combined high power signal and to supply the combined high power signal to a powered device in response to the sensed combined high power signal. Also disclosed is a local area network adapted to supply power to powered devices over a plurality of paths utilizing the combiner, the local area network thus supplying high power to a powered device.
