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 one onboard USB 3.0 port (USB 0) and one USB 2.0 port
(USB 1). The 10-pin connectors allow you to connect 4 additional USB 2.0 ports (USB 2-3/4-
5). 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.
BIOS Setting
Configure the onboard USB in the Advanced menu (“USB Configuration” submenu) of the
BIOS. Refer to chapter 3 for more information.
