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 X11SRL-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 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 (JPW1), and the 8-pin power con-
nector (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. It must also be SSI compliant. (For more information,

1.7 Serial Port

The X11SRL-F motherboard supports two serial communication connections. COM Port
(COM1) and header (COM2) 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.
