Hardware Installation
2.6.6 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 (J2 - Black) are
located at the ATX double deck ports
of the board. The J20 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
J20. The USB ports cable connector can be inserted only if pin 1 of
the cable is aligned with pin 1 of J20.
