environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notify the user of certain system events. For example, you can also confi gure
Supero Doctor to provide you with warnings when the system temperature, CPU
temperatures, voltages and fan speeds go beyond a predefi ned range.
2-5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible 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 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 confi guration control. ACPI leverages the Plug and
Play BIOS data structures, while providing a processor architecture-independent
implementation that is compatible with the Windows 2003, Windows XP, Windows
Vista 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.
2-6 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 X8DTU-6F+/X8DTU-6TF+/X8DTU-6(T)F+-LR motherboard accommodates 24-
pin ATX power supplies. Although most power supplies generally meet the specifi ca-
tions 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. Also
your power supply must supply 1.5A for the Ethernet ports.
Warning! 1. To avoid damaging 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 connectors to the 24-pin (JPW1) and the
two 8-pin (JPW2, JPW3) power connectors on the motherboard. Failure
to do so will void the manufacturer warranty on your power supply and
motherboard.
