1.5 ACPI Features
management features throughout a computer system, including its hardware, operating
peripherals such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
while providing a processor architecture-independent implementation that is compatible with
appropriate Windows operating systems. For detailed information regarding OS support,
please refer to the Supermicro website.
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 X12DAi-N6 motherboard accommodates a 24-pin ATX power supply. Although most
to the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use
power connectors (JPWR1/2/4) 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

1.7 Serial Port
The X12DAi-N6 motherboard supports one serial communication connections. 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.
