Intel Desktop Board D845GEBV2/D845GERG2 Technical Product Specification
42
1.13 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 I/O controller or the hardware monitoring and fan
control ASIC)
• Thermal and voltage monitoring
• Chassis intrusion detection
For information about Refer to
The WfM specification Section 1.5, page 20
1.13.1 Hardware Monitoring ASICs
The Desktop Boards provide one of the following:
• A hardware monitoring ASIC
• A hardware monitoring and fan control ASIC
The features of these components are described in this section. Contact your Intel sales
representative to determine which type of hardware monitoring ASIC is present on your Intel
Desktop Board.
1.13.1.1 Hardware Monitoring ASIC
The features of the hardware monitoring ASIC include:
• Internal ambient temperature sensor
• Remote thermal diode sensor for direct monitoring of processor temperature
• Power supply monitoring of four voltages (+5 V, +3.3 VSB, +1.5 V, and +VCCP) to detect
levels above or below acceptable values
• SMBus interface
For information about Refer to
The location of the fan connectors and sensors for thermal monitoring Figure 10, page 43
1.13.1.2 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 fans, that can adjust the fan speed or
switch the fans on or off as needed
• SMBus interface
