1.4 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines
a flexible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system, including its hardware, operating
system and application software. This enables the system to automatically turn on and off
peripherals such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
Windows operating systems.

1.5 Power Supply

As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates. In areas
where noisy power transmission is present, you may choose to install a line filter to shield
the computer from noise. It is recommended that you also install a power surge protector to
help avoid problems caused by power surges. It is strongly recommended that you use a high
quality power supply that meets ATX power supply Specification 2.02 or above. It must also be
SSI compliant. For more information, please refer to the website at http://www.ssiforum.org/.
The X11SWN-H/-E/-L/-C motherboard supports an 8-pin 12-24V DC input power supply at
JPWR1 for embedded applications. The 12-24V DC input is limited to 10A (12V) to 5A (24V)
by design. It provides up to 120W power input to the motherboard. Keep the onboard power
usage within the power limits specified above. Over current power usage may cause damage
to the motherboard.

1.6 Serial Port

The X11SWN-H/-E/-L/-C motherboard supports six serial communication connections. They
can be used for input/output. The UART provides legacy speeds with a baud rate of up to
115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which
support high-speed serial communication devices.
