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 X11SPi-TF 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 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 an 8-pin power connector. Be sure to connect
the power supplies to the 24-pin power connector (JPWR2), and the 8-pin power con-
nector (JPWR1) 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. 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 X11SPi-TF 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.
