Hardware Management Subsystem
5.3.1
Hardware Management
The hardware management features enable Intel® Server Boards to be compatible with the
Wired for Management (WfM) specification
.
The Intel® Entry Server Board SE7221BA1-E has
several hardware management features, including the following:
•
Fan monitoring and control (through the hardware monitoring and fan control ASIC)
•
Thermal and voltage monitoring
•
Chassis intrusion detection
5.3.2
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 chassis fans, that can adjust
the fan speed or switch the fans on or off as needed
•
SMBus interface
