1.11  Hardware Management Subsystem 
The hardware management features enable the Desktop Board D875PBZ to be compatible with the 
Wired for Management (WfM) specification.  The Desktop Board D875PBZ has the following 
hardware management features: 
•  Fan monitoring and control (through the I/O controller or the hardware monitoring and fan 
control ASIC) 
•  Thermal and voltage monitoring 
•  Chassis intrusion detection

1.11.1  Hardware Monitoring and Fan Control ASIC 
The features of the hardware monitoring and fan control ASIC (Standard Microsystems 
SMSC EMC6D101 or equivalent) 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 V Standby, +1.5 V, and +VCCP) 
to detect levels above or below acceptable values 
•  Thermally monitored closed-loop fan control, for all four fans, that can adjust the fan speed or 
switch the fans on or off as needed 
•  SMBus interface
