More Information
Summary:A network apparatus includes an independent power supply providing a first power signal, and a data distribution device which is operably coupled to the independent power supply and a remote data distribution device, where the remote distribution data device exchanges data and provides a second power signal to the data distribution device, and further where the data distribution device selects the first power signal or the second power signal for operational power. A method includes scanning a plurality of sensors, each coupled to a plurality of power inputs, to ascertain if a power signal is present, determining whether a power signal associated with an independent power supply is present at a power input, sourcing power from the independent power supply if the power signal is associated with an independent power supply, and sourcing power from an alternative supply if the power signal is not associated with an independent power supply.
