Abstract
A method for determining the classification of a powered device, the method comprising: obtaining a first classification over a first power path; obtaining a second classification over a second power path; comparing the obtained first classification with the obtained second classification; and in the event the obtained first classification is different from the obtained second classification determining a combined classification as a decoded value of the obtained first classification and the obtained second classification.
Claims9
Power sourcing equipment arrange to provide power via a plurality of output ports for connection over communication cabling to a single powered device, the power sourcing equipment comprising:
- a first power source operative to provide power via a first output port of the plurality of ports;
- a second power source operative to provide power via a second output port of the plurality of ports, said second output port different from said first output port;
- a control circuit;
- said control circuit being operative to obtain a first classification information indicative of the power requirements of the single powered device via said first output port and a second classification information indicative of the power requirements of the single powered device via said second output port and in the event that said obtained first classification information does not equal said obtained second classification information to identify the connected single powered device as a powered device capable of receiving power over a combination of said first output port and said second output port.
