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. |

1. A Information Handling System (HIS), comprising:
a chassis; a plurality of ports that are located on the chassis, wherein each of a first port and a second port of the plurality of ports are configured to both send and receive data and provide power, and a third port of the plurality of ports is configured to both send and receive data and receive power; and a power distribution engine that is included in the chassis and that is coupled to each of the plurality of ports, wherein the power distribution engine is configured to:
determine that power available to the power distribution engine is insufficient to power a powered device that is coupled to the first port;send, through the third port, data that includes a request for power from a first powering device that is coupled to the third port and that is not providing power through the third port prior to the sending of the request through the third port;receive, through the third port subsequent to the sending of the request through the third port, power from the first powering device;provide, through the first port to the powered device, power that is received through the third port from the first powering device; andsend and receive, through the first port, data with the powered device. |
