Method and network for providing backup power to networked devices
First Claim
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;
applying at least the power signals to a secondary power module;
conditioning power from a secondary power source in the secondary power module; and
applying power to the networked component from the network during normal operation, and from the secondary power module in the event of a predetermined drop in voltage of power from the network.

Abstract
A network is configured to apply power and data signals to networked devices for operation of the devices. A backup power supply module is coupled to the source of network power and to a secondary power source. The secondary power source may have an adjustable voltage level or a level fixed with relation to the network power voltage level. In the event of a loss or insufficiency of network power, power from the secondary source is automatically applied to the connected device or devices. The device may be programmed for certain failure modes and the secondary power source provides the power needed for operation in the event of loss of network power.
