Features a built-in standard 3-port 10-/100-/1000-Mbps switch. Auto MDI/MDI-X means no need for a crossover cable. This PoE Repeater acts as a PoE extender, enabling you to extend PoE connections beyond the 100-meter limit to access faraway PoE devices such as access points, cameras, and VoIP phones. The repeater passes along both data and power, so it needs no separate power supply -- use one repeater for an additional 100 meters (328 ft.) in your application or daisychain two repeaters to extend the reach of your PoE an additional 200 meters (656 ft.) on top of the standard PoE distance of 100 meters (328 ft.) for a total reach of up to 300 meters (984 ft.) Because each repeater uses about 2 watts itself, we do not recommend daisychaining more than two units. Two daisychained repeaters support a PoE PD end device that needs up to 7 watts, perfect for VoIP phone networks. This PoE repeater provides one (1) 10/100/1000 PD input port, one (1) 10-/100-/1000-Mbps PSE output port, and a standard a 3-port 10/100/1000 switch.
