Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 20 on page 39 for the location of the chassis intrusion header.

Power Management Features

Power management is implemented at several levels, including:

Advanced Configuration and Power Interface (ACPI)

Hardware support:

Power connectors

Fan connectors

Suspend to RAM (Instantly Available PC technology)

Wake from USB

Wake from PS/2 keyboard/mouse

PME# wakeup support

ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support.

Power Connectors

The desktop board has two power connectors. See Figure 22 on page 43 for the location of the power connectors.

Fan Connectors

The desktop board has three fan connectors. One processor fan header (4-pin) and two chassis fan headers (3-pin). See Figure 21 on page 42 for the location of the fan headers.

Fan Speed Control (Intel® Precision Cooling Technology)

Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor thermal diode temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds.

The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control remain enabled (default BIOS setting) when using the processor fan heat sink included with Intel® boxed processors. Disabling the chassis fan speed control results in chassis fans always
