摘要： A network switch includes a power connection configured to receive power from a primary power source and at least two ports. At least a first one of the ports is configured to connect to a first network interface of a first computing device through a communication medium configured to conduct operating power for the network switch. The first network interface is configured to draw electrical power from a power supply of the first computing device and provide, through the network cable, at least a portion of the drawn electrical power as the operating power. A switching circuit is configured to route network data between the ports and a power management circuit coupled at least to the first port. The power management circuit is configured to draw at least a portion of the operating power from the first port, and power the switching circuit using the drawn power responsive to a detected failure of the primary power source.

摘要： A method of booting an electronic device includes verifying communicable connection of a sender input/output terminal of the electronic device to a receiver input/output terminal of the electronic device, using a first boot loader executing on a computing processor of the electronic device. The method further includes reading a signature of a unique identifier of the electronic device from a removable storage device received by the electronic device, verifying the signature of the unique identifier of the electronic device, and allowing installation of a second boot loader on the electronic device when the signature is valid.
