Chapter 1: Introduction
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 conguration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
Windows 7, Windows 8, and Windows 2012 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.
The X11SSM(-F)/X11SSL(-F) motherboard accommodates 24-pin ATX power supplies.
Although most power supplies generally meet the specications required by the CPU, some
are inadequate. In addition, One 12V 8-pin power connection is also required to ensure
adequate power supply to the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use a
power supply that contains a 24-pin and one 8-pin power connector. Be sure to con-
nect the power supplies to the 24-pin power connector (JPWR1), and the 8-pin power
connector (JPWR2) on the motherboard. Failure in doing so may void the manufacturer
warranty on your power supply and motherboard.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specication 2.02 or above. It must also be SSI compliant. (For more information,
please refer to the website at http://www.ssiforum.org/). Additionally, in areas where noisy
power transmission is present, you may choose to install a line lter 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.
1.7 Serial Port
The X11SSM(-F) motherboard supports two serial communication connections. X11SSL(-F)
supports COM Port 1 only. COM Ports 1 and 2 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.
