Abstract
A power distribution system includes a chassis with a plurality of ports that include a first port configured to communicate with powering devices and a second port configured to communicate with powered devices. A power distribution engine in the chassis is coupled to each of the plurality of ports. The power distribution engine determines that power available to the power distribution engine is insufficient to power a first powered device that is coupled to the first port, requests power from a first powering device that is coupled to the second port, and provides power that is received through the second port from the first powering device to the first powered device through the first port. In an embodiment, the first powered device and the second powered device are switch IHSs, the first port is configured as a trunk port, and the second port is configured as an access port.
