A power management processor is coupled to each of the uplink ports and the user device ports. The power management processor is operable to determine a power budget using power received by the uplink ports. The power management processor is also operable to detect a port configuration event such as the removal of a connection of a user device to a user device port, the inactivity of a user device port, or the addition of a connection of a user device to a user device port, and in response, selectively provide power to one or more of the plurality of user device ports based on the power budget and the port configuration event."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PoE power distribution system for PoE-powered port extender having multiple data and power inputs","description":"A port extender includes a chassis with uplink ports that are operable to receive power and data from a power sourcing device, and user device ports that are operable to connect to user devices.
