Abstract:
A bootloader system is provided, which includes a volatile memory, a first non-volatile memory configured to store a first bootloader, and a second non-volatile memory configured to store a second bootloader. The first bootloader, when executed by a microprocessor, causes the microprocessor to control at least one of the volatile memory or the second non-volatile memory to receive an updated second bootloader and pass the updated second bootloader through the at least one of the volatile memory or the second non-volatile memory to the second non-volatile memory.
Abstract:
Power systems, devices, and methods include a plurality of network interfaces for providing communication to, e.g., a management server, console, or user interface. One or more controllers coupled to power circuitry determine whether a preferred one of the network interfaces has connectivity, and directs communication over the preferred network interface in response to a determination that the preferred network interface does have connectivity. The controller directs communication over an alternate one of the network interfaces in response to a determination that the preferred network interface does not have connectivity.
