1. A method for providing power to a networked component coupled to a data and power network, the method comprising:

  • applying data and power signals to the networked component via the network, the power signals providing direct current power;

    converting alternating current power from a power source to direct current secondary power in a secondary power module;

    applying power to the networked component from the network during normal operation;

    comparing a voltage level of power from the network and a voltage level of power from the secondary power module; and

    transitioning application of power to the networked component from the network to application of power from the secondary power module based upon the comparison,wherein power is applied from the secondary power module in the event of a predetermined drop in voltage of power from the network.
