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 port (USB 0-1) and two onboard USB
2.0 ports (USB 4-5) at the rear panel I/O ports. The 10-pin connectors allow you to connect
2 additional USB 2.0/1.1 ports (USB 6-7). The 20-pin connector is designed to connect 2 ad-
ditional USB 3.0 ports (USB 2-3). The 5-pin connector allows you to connect 1 additional USB
2.0/1.1 port (USB 10) or co-lays with 1 vertical USB 2.0/1.1 port (type A). 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.
