2.8.6 Universal Serial Bus Ports
The system board supports 4
USB ports. USB allows data
exchange between your computer
and a wide range of
simultaneously accessible external
Plug and Play peripherals. You
must have the proper drivers
installed in your operating system
to use the USB ports. Refer to
your operating systems manual
or documentation.
Two onboard USB ports (J1 -
Black) are located at the ATX
double deck ports of the board.
The J21 connector on the system
board allows you to connect the optional 3rd and 4th USB ports.
These optional USB ports, which are mounted on a card-edge
bracket, will be provided as an option. If you wish to use the
optional 3rd and 4th USB ports, install the card-edge bracket to the
system chassis then insert the connector that is attached to the USB
port cables to J21. The USB ports cable connector can be inserted
only if pin 1 of the cable is aligned with pin 1 of J21.
