# Power Supplies

## DC Power Adapter

The router includes a default AC/DC power adapter. Plug the AC connector into a 110-240V electrical outlet, and connect the DC plug to the DC socket on the router. The router will power on automatically when DC power is connected.

## Alternative Power Sources

Higher voltages and currents can damage the router, and insufficient voltages and currents might not be able to power up the router or reduce the operating performance.

### DC Power

The DC socket could take a wide range of 9\~48Volt DC power. Do not overload it! The typical DC power is 12Volt 2Amps. The DC jack should be Ø5.5 x 10mm, and the inner pin should be Ø2.1mm.

### PoE Power

You can use an IEEE802.3af/at standard PoE injector or PoE switch to input electric power on the "PoE & WAN" and "PoE & LAN" ports. They activate the WAN and LAN connections through the PoE LAN cable.
