1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a exible and abstract hardware interface that provides a standard

way to integrate power management features throughout a PC system, including

hardware, operating system and application software. This enables the system to

automatically turn on and off 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 interface for conguration control. ACPI leverages the Plug and

Play BIOS data structures, while providing a processor architecture-independent

implementation that is compatible with Windows 7, Windows 8, and Windows 2008

Operating Systems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will "wake up" and the LED will automatically stop blinking and remain on.

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 X9DB3/i-F/-TPF motherboard accommodates 24-pin ATX power supply. Al-

though most power supplies generally meet the specications required by the CPU,

some are inadequate. In addition, two 12V 8-pin power connectors (JPW2/JPW3)

and the 4-pin power connector (JPW4) are also required to ensure adequate power

supply to the system. Your power supply must also supply 1.5A for the Ethernet

ports.

Warning! To ensure adequate power supply to the motherboard, please use a power

supply that contains a 24-pin, two 8-pin and one 4-pin power connectors. Be sure to

all power connectors on the motherboard to the power supply. 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 Specication 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
