1.10.3 Fan
Monitoring
Fan monitoring can be implemented using Intel
®
Desktop Utilities or third-party software. The
level of monitoring and control is dependent on the hardware monitoring ASIC used with the
Desktop Board.

Refer to
The functions of the fan connectors
Section 1.11.2.2, page 33
1.10.4 Chassis Intrusion and Detection
The board supports a chassis security feature that detects if the chassis cover is removed. The
security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion
connector. When the chassis cover is removed, the mechanical switch is in the closed position.

1.11.1 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 this board requires an operating system that
provides full ACPI support. ACPI features include:
•
Plug and Play (including bus and device enumeration)
•
Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video displays, and hard disk drives
•
Methods for achieving less than 15-watt system operation in the power-on/standby
sleeping state
•
A Soft-off feature that enables the operating system to power-off the computer
•
Support for multiple wake-up events (see Table 8 on page 32)
•
Support for a front panel power and sleep mode switch
