In one or more implementations, the system includes a first power over Ethernet (PoE) powered device controller configured to control power supply to a load, and a second PoE powered device controller coupled to the load and to the first PoE powered device controller. The second PoE powered device controller is connected to the first PoE powered device controller using a shared connection interface and is configured to control power supply to the load. The shared connection interface is configured to synchronize the first PoE powered device controller and the second PoE powered device controller to deliver power at least substantially contemporaneously to the load."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Powered device controllers having shared connection interfaces and two-level inrush current limit","description":"A system for controlling the operation of isolation transistors in high power Power over Ethernet (PoE) networks to achieve greater power delivery to a load is disclosed.
