Fan Monitoring; Chassis Intrusion And Detection; Power Management; Acpi - Intel DESKTOP BOARD D955XBK Manual

Intel Desktop Board D955XBK Technical Product Specification

1.13.3 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.

The functions of the fan connectors

1.13.4 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.

1.14 Power Management

Power management is implemented at several levels, including:
•
Software support through Advanced Configuration and Power Interface (ACPI)
•
Hardware support:
⎯ Power connector
⎯ Fan connectors
⎯ LAN wake capabilities
⎯ Instantly Available PC technology
⎯ Resume on Ring
⎯ Wake from USB
⎯ Wake from PS/2 devices
⎯ Power Management Event signal (PME#) wake-up support
⎯ PCI Express WAKE# signal support

1.14.1 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 39)
•
Support for a front panel power and sleep mode switch
