The USB device allows data exchange between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
In addition to the rear USB ports as introduced previously in this chapter, the system board is
equipped with four internal USB 2.0 ports (two pin headers) as illustrated above.
The internal USB pin headers may be connected to a card-edge bracket. Install the card-edge
bracket to an available slot at the rear of the system chassis and then insert the USB port
cables to a connector.
Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse
to wake up a system from the S state(s).

The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
COM 1 supports three serial modes, i.e. RS232 (with or without power), RS422, and RS485.
COM 2 only supports RS232.
Jumper Setting
RS232 with/without power of COM 1 is configured via jumper settings as previously instructed
in this chapter.
