Hardware Management Subsystem
The hardware management features enable the Desktop Boards to be compatible
with the Wired for Management (WfM) specification. The Desktop Board 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
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
Thermal Monitoring
Figure 11 shows the location of the sensors and fan connectors.
