Hardware Management Subsystem (Optional); Hardware Monitoring And Fan Control Asic; Fan Monitoring; Chassis Intrusion And Detection - Intel D845PEMY Specification

Intel Desktop Board D845PEMY Technical Product Specification

1.11 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

1.11.1 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

1.11.2 Fan Monitoring

Fan monitoring can be implemented using LANDesk* Client Manager or other third-party
software.

1.11.3 Chassis Intrusion and Detection

The board supports a chassis security feature that detects if the chassis cover is removed. The
security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion
connector. When the chassis cover is removed, the mechanical switch is in the closed position.
