neously accessible external Plug and Play peripherals.
The system board is equipped with four onboard USB 2.0/1.1 ports. The USB 4-5

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 then insert the
cable connector to a USB connector.
