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-F 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 8-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 8-pins, respectively. 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 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-F motherboard supports two serial communication connections. COM Port 1
and COM Header 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.
