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:
• The Legacy I/O Controller smart fan control, delivering acoustically-optimized
thermal management
• Fan speed control controllers and sensors integrated into the Legacy I/O Controller
• Four thermal sensors (processor, 82G41 GMCH, 82801GB ICH7, and a remote
thermal sensor)
• Power supply monitoring of five voltages (+12 V, +5 V, +3.3 V, +1.125 V, and
+VCCP) to detect levels above or below acceptable values
• Thermally monitored closed-loop fan control, for both fans, that can adjust the fan
speed according to thermal conditions
1.11.2 Fan Monitoring
Fan monitoring can be implemented using third-party software. The level of
monitoring and control is dependent on the I/O controller used with the board.

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.
