Intel Desktop Board DP45SG Technical Product Specification

Product Description

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 provided by the Hardware Monitoring

and Fan Control ASIC

• Thermal sensors in the processor, 82P45 MCH, 82801JR ICH10R, and remote

thermal sensors

• Power supply monitoring of five voltages (+5 V, +12 V, +3.3 V, +1.125 V, and

+VCCP) to detect levels above or below acceptable values

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

fan speed according to thermal conditions

1.11.2 Fan Monitoring

Fan monitoring can be implemented using Intel

Desktop Control Center or third-party

software.

The functions of the fan headers Section 1.12.2.2, page 33

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.
