The system board supports 4 USB
por ts. 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
por ts. Refer to your operating
system’s manual or documentation.
Two onboard USB ports (CN4 -

double deck ports of the board.
The 9-pin connector (J18 - USB 2) on the system board allows you
to connect 2 additional external USB ports. One USB card mounted
with two USB ports is provided with the system board. If you want
to use these ports, mount the USB card to the system chassis then
insert the other end of the cable that is attached to J1 of the USB
card to J18 on the system board. The cable connector can be in-
serted only if pin 1 of the cable is aligned with pin 1 of J18.
