US 10,122,545 B2 · Power forwarding via a powered device

Abstract

The present invention relates to a powered device (331a, 331b, 531a) with two interfacing connections. The powered device (331a, 331b, 531a) comprises power switching units (350a, 350b, 550a1, 550a2) for forwarding the data signal as well the power received on the input to the output. Forwarding may be based on a detection of the powering state of the PD. In another embodiment, the Power-over-Ethernet input/output ports function bi-directionally, thereby allowing the user to daisy-chain devices in any direction. As power switching units, relays or solid-state power switches may be used.

Dependent claims

A powered device for use in a Power-over-Ethernet network where power is supplied through network connections, said powered device comprising:

a first port;
a second port;
and
a power switching unit configured to enable power forwarding via said second port in a first mode, and to disable power forwarding via said second port in a second mode;
characterized in that said powered device is configured to detect whether the first port receives power directly from a power sourcing equipment of said Power-over-Ethernet network or alternatively via a second powered device based on whether said first port receives power without prior negotiation.
