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 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 X11SSA-F/X11SSi-LN4F motherboard accommodates 24-pin ATX power supplies.
Although most power supplies generally meet the specifications 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 power connector and an 8-pin power connector.
Be sure to connect the power supplies to the 24-pin power connector (JPWR1), and
the 8-pin power connector (JPWR2) on the motherboard. Failure to do 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 Specification 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 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.
1.7 Serial Port
The X11SSA-F/X11SSi-LN4F motherboard supports two serial communication connections.
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.
