Beschreibung
Zusammenfassung:	A chainable Power over Ethernet Node (CPEN) is provided according to the invention. The CPEN contains an electronic circuit and control method to pass power, communications, or both power and communications to subsequent chainable nodes or other devices. The invention allows one cable run to serve a plurality of chainable nodes thus greatly reducing the amount of cable required. The invention enables redundant connections in both power and communications to network nodes to prevent failure in case of cable or node fault. The chainable node has 2 or more ports, all of which are interchangeable. Any port can respond to PoE Powered Device (PD) classification and receive power. Any port can act as a Power Supplying Equipment (PSE) to enable power to subsequent nodes. The ports can support standards compliant PoE detection, classification, and operation, and can support non-standard variations.
