1. A device for providing power to a network-based device comprising:
- a first circuit adapted to provide a differential voltage based on input signals of opposite polarity received from a first pair of network pathways or to contribute to the provisioning of a common voltage based on input signals of a first polarity received from the first pair of pathways; and
a second circuit adapted to supply the differential voltage based on input signals of opposite polarity received from a second pair of network pathways or to contribute to the provisioning of the common voltage based on input signals of a second polarity received from the second pair of pathways.
