Super X11SCL-IF User's Manual
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 where
noisy power transmission is present.
The X11SCL-IF motherboard accommodates a 24-pin ATX power supply. Although most
power supplies generally meet the specifications required by the CPU, some are inadequate.
In addition, one 12V 4-pin power connection is also required to ensure adequate power to
the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use
power supplies that contain 24-pins and 4-pins, respectively. Connect the power sup-
plies to the 24-pin power connector (JPW1), and the 4-pin power connector (JPW2)
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 Specification 2.02 or above and is SSI compliant. (For more information, please refer
to the website at http://www.ssiforum.org/).
1.7 Serial Port
The X11SCL-IF motherboard supports one serial communication connection. COM Port 1
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.
