Abstract: An apparatus includes an AC-to-DC power supply, with a positive terminal operatively coupled to two two-wire pairs of an Ethernet port to provide a first and second power path over a structured cable. A negative terminal is operatively coupled to a third two-wire pair of the Ethernet port to complete the first power path. Power path control logic has an input port operative to receive a two-wire input signal from an external device, and is operatively coupled to the negative terminal of the AC-to-DC power supply output, and to a fourth two-wire pair of the Ethernet port to complete the second power path. The power path control logic is operative to disconnect the negative terminal of the AC-to-DC power supply from the fourth two-wire pair of the Ethernet port in response to a two-wire input signal received at the input port, to disconnect the second power path.

Abstract: An apparatus includes a plurality of power distribution control output channels operatively coupled to at least one power source, and comprising an access control input from an access control device, and a control output for a controlled device. A controller receives an access control input signal for each power distribution control output channel and provides a control signal to each power distribution control output channel such that each power distribution control output channel provides a control output signal according to requirements of a corresponding controlled device. The controller can individually isolate one or more power distribution control output channels from the at least one power source such that the control output signal is removed from the corresponding controlled device, while any other power distribution control output channels coupled to the same power source continues to operate without interruption.

Abstract: A method of operation includes receiving, by a power supply with battery backup, a battery test command from a user interface on a remote device, switching the power supply to the battery backup in response to the battery test command, monitoring voltage and discharge current of the battery, determining that the battery has reached a threshold capacity due the battery discharge, terminating the battery discharge test and switching the power supply off of the battery backup. The battery backup test command received may be a one-click selection input at a user interface on the remote device where the battery test command is sent to the power supply in response to the one-click selection input. An apparatus that performs the method of operation is also disclosed.
