  • Power sharing network communications device
    Patent number: 8310089
    Abstract: A set of network communications devices shares available power among themselves to meet overall system power loading. An individual device is configured to include a local power supply delivering power to a local power bus at a local supply voltage varied in response to a voltage control signal. A protection component is connected between the local power bus and an external power cable used to connect the device to another device for sharing power. The protection component provides an interruptible low-impedance DC path for carrying current based on direction and magnitude of a voltage difference between the local power bus and the external power cable.
