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 two onboard USB 3.0 ports (USB 0-1) and four onboard
USB 2.0 ports (USB 4-5/8-9). The 10-pin connectors allow you to connect 4 additional USB
2.0/1.1 ports (USB 2-3/10-11). The additional USB ports 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.
