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:
• Chassis intrusion detection
• Fan monitoring and control (through the hardware monitoring and fan control ASIC)
• Thermal and voltage monitoring
1.11.1 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, +1.5 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
• SMBus interface
