Hardware Installation
2.10.6 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 por ts
(USB 1 - Black) are located
at the ATX double deck
ports of the board. The
USB 2 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 USB 2. The USB ports cable connector can be in-
serted only if pin 1 of the cable is aligned with pin 1 of USB 2.
