to provide you with warnings when the system/CPU temperatures, CPU voltages
and fan speeds go beyond a predefined range.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specifica -
tion defines a flexible and abstract hardware interface that provides a standard way
to integrate power management features throughout a PC system, including its
hardware, operating system and application software. This enables the system to
automatically turn on and off peripheral devices 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 configuration control. ACPI leverages the Plug and
Play BIOS data structures, while providing a processor architecture-independent
implementation that is compatible with Windows 2008, Windows Vista and Windows
7 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 X9DAi motherboard accommodates 24-pin ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU, some
are inadequate. In addition, two 12V 8-pin power connections 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 prevent damage to the power supply or motherboard, please
use a power supply that contains a 24-pin and two 8-pin power connec-
tors. Be sure to connect these power supply connectors to the 24-pin (J22)
and two 8-pin power connectors (JPWR1, JPWR2) on the motherboard.
Failure to do so will void the manufacturer warranty on your power supply
and motherboard.
