USB Ports
The USB device allows data exchange between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
The system board is equipped with 2 onboard USB 2.0 ports (USB 1-2). The 6-pin connec-
tor allows you to connect 1 additional USB 2.0 port (USB 3). The additional USB port may be
mounted on a card-edge bracket. Install the card-edge bracket to an available slot at the rear
of the system chassis and then insert the USB port cables to a connector.
