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 2012/R2 and 2016 Server operating systems.
1.6 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.
The X11SDW-4C/8C/16C-TP13F motherboard supports an 8-pin 12V DC input power supply
at JPV1 for embedded applications. The 12V DC input is limited to 30A by design. It provides
up to 360W 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.
1.7 Super I/O
The Super I/O (AST2500) provides high-speed, 16550 compatible serial communication ports
(UART), which support serial infrared communication. The UART includes send/receive FIFO,
a programmable baud rate generator, complete modem control capability, and a processor
interrupt system. The UART provides legacy speed with 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, supporting higher
speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power
Interface), which includes support of legacy and ACPI power management through a SMI
or SCI function pin. It also features auto power management to reduce power consumption.
