High power architecture for power over Ethernet
First Claim
1. A local area network adapted to supply power over a plurality of communication cabling paths, the local area network comprising:
- a powered device;
a power sourcing equipment; and
a communication cabling comprising a plurality of twisted wire pairs connecting said power sourcing equipment to said powered device, said communication cabling providing a first power path comprising a first set of twisted wire pairs of said communication cabling and a second power path comprising a second set of twisted wire pairs of said communication cabling, said first set being different from said second set;
said power sourcing equipment comprising;
a control circuit;
a first power source responsive to said control circuit adapted to supply a first power to said powered device via said first power path; and
a second power source responsive to said control circuit adapted to supply a second power to said powered device via said second power path,said control circuit being operative to;
supply said first power to said powered device from said first power source via said first power path;
contemporaneously with said supplied power from said first power source, supply said second power to said powered device from said second power source via said second power path; and
control said first power source such that a current component of said first power is maintained within a pre-determined range.
