Environmental Temperature Control
System Health sensors monitor temperatures and voltage settings of onboard processors and
the system in real time via the BMC interface. Whenever the temperature of the CPU or the
system exceeds Supermicro’s pre-dened threshold, the system and CPU cooling fan speed
will increase to prevent the CPU or system from overheating.
Note: To avoid possible system overheating, please be sure to provide adequate air-
ow to your system.
System Resource Alert
This feature is available when used with SuperDoctor 5
®
in the Windows OS environment.
SuperDoctor is used to notify the user of certain system events. For example, you can
congure SuperDoctor to provide you with warnings when the system temperature, CPU
temperatures, voltages and fan speeds go beyond a predened range.
1.5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specication denes
a exible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system, including its hardware, operating
system and application software. This enables the system to automatically turn on and off
peripherals such as 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
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 X12DPi-N(T)6 motherboard accommodates a 24-pin ATX power supply. Although most
power supplies generally meet the specications 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.
Warning! To avoid damaging the power supply or the motherboard, be sure to use a power
supply that contains a 24-pin and two 8-pin power connectors. Be sure to connect the power
supplies to the 24-pin power connector (JPWR3), and the 8-pin power connectors (JPWR2/
JPWR4) on the motherboard. Failure in doing so may void the manufacturer warranty on your
power supply and motherboard.
