  • a first network connector configured to connect to a first wired network port of the daisy-chained network device;

    a second network connector configured to connect to a second wired network port of the daisy-chained network device;

    a normally-closed switch having a first terminal, a second terminal and a pole, the first terminal electrically connected to the first network connector, the second terminal electrically connected to the second network connector, and the pole, when energized, opening the normally-closed switch such that the first and second terminals are electrically isolated from one another; and

    a resettable timer having an input port and an output port, the input port configured to receive reset signals, the output port electrically coupled to the pole of the normally-closed switch, the resettable timer configured to generate an output signal on the output port that energizes the pole during a predetermined time period following every reset signal received and de-energizes the pole after the predetermined time period following a last of the received reset signals.
