2.2.5.6 Universal Serial Bus Ports
The system board is equipped with a header, at location J11 on
the system board, for external 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 these ports. Refer to your operating system' s
manual or documentation.
Connecting the USB Ports
As an option, one card-edge bracket mounted with two USB port
cables may be provided with the system board. The ends of the
cables are attached to a connector. Connect the USB cable
connector to J11 on the system board. The USB port cables can be
inserted only if pin 1 of the cable (red wire) is aligned with pin 1 of
J11. Pin 5 of J11' s USB 2 has been removed and the hole in the
USB cable connector, which corresponds to pin 5, has been plugged
to prevent incorrectly inserting the connector. Mount the card-edge
bracket to the system chassis.
