1.10.3
Fan Monitoring
Fan monitoring can be implemented using Intel
®
Desktop Utilities, LANDesk* software, or third-
party software.
The level of monitoring and control is dependent on the hardware monitoring ASIC
used with the Desktop Board.
For information about
Refer to
The functions of the fan connectors
Section 1.11.2.2, page 36
1.10.4
Chassis Intrusion and Detection
The boards support 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.
For information about
Refer to
The location of the chassis intrusion connector
Figure 16, page 48
The signal names of the chassis intrusion connector
Table 18, page 50
1.11 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
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 these boards 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 35)
•
Support for a front panel power and sleep mode switch
