1.12  Hardware Management Subsystem (Optional) 
The hardware management features enable the boards to be compatible with the Wired for 
Management (WfM) specification.  The board has several hardware management features, 
including the following: 
•  Fan monitoring (through the I/O controller or the hardware monitoring and fan control ASIC) 
•  Thermal and voltage monitoring 
•  Chassis intrusion detection

1.12.1  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 
•  Fan monitoring for all three fan connectors
