Abstract
A network apparatus and method for managing power supplied to a network device. A plurality of power inputs to the network device are scanned to ascertain if a power signal is present and to identify an active power source. Available power is determined from the active power source and required power for the network device and any operatively connected auxiliary devices is also determined. The required power is compared to available power to determine if available power is sufficient to power the network device. An operation of the network device is controlled based upon the active power source and/or if available power is insufficient to power the network device.
