USB Ports
USB allows data exchange between your computer and a wide range of simultaneously acces-
sible external Plug and Play peripherals.
The system board is equipped with four onboard USB 3.0/2.0/1.1 ports (USB 0-3) and two
onboard USB 2.0/1.1 ports (USB 8-9). The two 10-pin connectors allow you to connect 4 addi-
tional USB 2.0/1.1 ports (USB 4-7). 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.
