Hardware Installation
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 system’s manual or documentation.
Two onboard USB ports (J2 - Black) are located at the ATX double
deck ports of the board.
Depending on the type of USB port cable that you are using, the
J19 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 J19. The USB ports’ cable
connector can be inserted only if pin 1 of the cable is aligned with
pin 1 of J19.
Insert the USB port cable connector to pins 1-10 if:
• One of the holes on the cable connector is plugged, meaning the
cable connector has a keying mechanism.
Insert the USB port cable connector to pins 6-15 if:
• None of the holes on the cable connector is plugged, meaning
the cable connector has no keying mechanism.
