1.10 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:
• Chassis intrusion detection
• Fan monitoring and control (through the hardware monitoring and fan control ASIC)
• Thermal and voltage monitoring
1.10.1 Hardware Monitoring and Fan Control ASIC
The features of the hardware monitoring and fan control ASIC include:
• Internal ambient temperature sensor
• Two remote thermal diode sensors for direct monitoring of processor temperature and ambient
temperature sensing
• Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, 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
• SMBus interface

The location of the fan connectors and sensors for thermal monitoring Figure 10, page 34
1.10.2 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
connector. When the chassis cover is removed, the mechanical switch is in the closed position.
1.10.3 Fan Monitoring
Fan monitoring can be implemented using Intel Desktop Utilities or third-party software. The level
of monitoring and control is dependent on the hardware monitoring ASIC used with the board.
