Abstract
A technique is provided for applying secondary or backup power to a networked device in the event of a loss or malfunction of network power. In a control and monitoring network. Various devices may receive both power and data signals from a network cable. In the event of loss of network power, or the reduction in network power, the devices can automatically and without interruptions seek power from the secondary power source.
