METHOD AND APPARATUS FOR DISTRIBUTING POWER OVER COMMUNICATION CABLING
First Claim
1. A powered telecommunications device, comprising:
- a first powered device port unit configured to negotiate receipt of a level of power from power sourcing equipment, the power received on a first pair of taps;
a detection unit configured to detect a presence of a first optional load and to detect a presence of a second optional load;
a control circuit configured to establish connectivity between a second pair of taps and the first optional load circuit in response to the detection unit detecting the first optional load; and
the control circuit further configured to establish connectivity between the second pair of taps and a third pair of taps in response to the detection unit failing to detect the first optional load and detecting the second optional load.

Abstract
A PoE powered device and method of operation are provided. The device includes a first port unit configured to negotiate receipt of a level of PoE power from a power sourcing equipment. The power is received on a first pair of taps on a first communication port. A detection unit is configured to detect a presence of a first optional circuit load and to detect a presence of a second optional power load. A control circuit is configured to establish connectivity between a second pair of taps on the first communication port and a second powered device port unit in response to the detection unit detecting the first optional load, and further configured to establish connectivity between the second pair of taps and a third pair of taps on a pass-through communication port in response to the detection unit failing to detect the first load and detecting the second load.
