Abstract: A technique is able to direct a power signal from a port power controller to one of multiple physical ports. The technique involves activating a set of port power controllers. Each port power controller is constructed and arranged to deliver power to a device through at most one physical port at a time. The technique further involves performing a set of discovery operations to discover device presence, the set of discovery operations providing discovery data. The technique further involves providing, based on the discovery data provided by the set of discovery operations, a set of switching signals to switching circuitry which is coupled to a set of physical ports. The switching circuitry is constructed and arranged to steer power signals from the activated set of port power controllers through the set of physical ports to deliver power to a set of devices.
