1.11 Hardware Management Subsystem; Hardware Monitoring And Fan Control; Fan Monitoring; Chassis Intrusion Detection - Intel BLKDP43BF 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 Intel ICH10R
• Remote thermal diode sensor for ambient temperature sensing
• Thermal sensors in the processor, Intel 82P43 MCH, and Intel 82801JIR (Intel
ICH10R)
• 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 three fans, that can adjust the
fan speed according to thermal conditions
1.11.2

Fan Monitoring

Fan monitoring can be implemented using Intel
software.

1.11.3 Chassis Intrusion 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.
