Embodiments of power sourcing equipment (PSE) utilizing AC disconnect are provided herein. In one embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage over a data communications medium, a controller configured to provide an AC disconnect signal over the data communications medium, and a parallel inductor-capacitor (LC) circuit coupled between the DC supply and the data communications medium. The parallel LC circuit is configured to isolate the DC supply from the AC disconnect signal. In another embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage at an output, an inductor coupled between the output of the DC supply and a data communications medium, and a capacitor coupled between the data communications medium and ground. The inductor and capacitor form a series LC circuit configured to generate an AC disconnect signal.
