Intel Desktop Board DG31PR Technical Product Specification

1.11 Hardware Management Subsystem

The hardware management features enable the board to be compatible with the Wired

for Management (WfM) specification. The board has several hardware management

features, including the following:

• Fan monitoring and control

• Thermal and voltage monitoring

• Chassis intrusion detection

1.11.1 Hardware Monitoring and Fan Control

The features of the hardware monitoring and fan control include:

• Fan speed control controllers and sensors integrated into the legacy I/O controller

• Remote thermal diode sensor for ambient temperature sensing

• Thermal sensors in the processor, 82G31 GMCH, and ICH7

• Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.25 V, and

+VCCP) to detect levels above or below acceptable values

• Thermally monitored closed-loop fan control, for all three fans, that can adjust the

fan speed or switch the fans on or off as needed

1.11.2 Fan Monitoring

Fan monitoring can be implemented using Intel

Desktop Utilities or third-party

software.

The functions of the fan headers Section 1.12.2.2, page 34

1.11.3 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 header. When the chassis cover is removed, the mechanical

switch is in the closed position.
