Abstract: One or more Power Sourcing Equipment (PSE) are coupled to points in a network of interconnected nodes. Each node has a first port and a second port. Assume the first port of a first node is receiving DC power from the PSE. The first node, at its second port, then detects an electrical signature from a first port of an adjacent second node. If the proper electrical signature is presented by the adjacent second node, the powered first node closes a switch to pass power between its first port and second port to power the second node via the first port of the second node. All nodes in the network are then sequentially powered up in this manner. If there is a fault between the first node and the second node, the second node will be powered by another node connected to the second port of the second node.
