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

interface for configuration control. ACPI leverages the Plug and Play BIOS data structures,

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 X13DDW-A motherboard accommodates two 8-pin power connectors (JPWR1/JPWR2)

and a 24-pin power connector (JPWR3). Although most power supplies generally meet the

specifications required by the CPU, some are inadequate. All these power connections are

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 accommodates two 8-pin power connectors (JPWR1/JPWR2) and

a 24-pin power connector (JPWR3) for your system. Failure to do 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/).

The X13DDW-A motherboard supports one serial port on the rear I/O panel. COM Port 1

can be used for input/output. The UART provides legacy speeds with a baud rate of up to

115.2 Kbps.
