Intel Desktop Board DP43BFL Product Guide Hardware Management Features The hardware management features of Intel Desktop Board DP43BFL enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following: • Fan speed monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection Fan Speed, Thermal, and Voltage Monitoring and Control Features of the board's fan speed, thermal, and voltage monitoring and control subsystem include: • Monitoring of power supply voltages to detect levels above and below acceptable values. • Smart fan control provided by the legacy I/O controller, delivering acoustically- optimized thermal management. Fan speed controllers and sensors are integrated into the legacy I/O controller. • Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed according to thermal conditions. • Two thermal sensors (processor and a remote thermal sensor). Chassis Intrusion The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the Desktop Board. See Figure 22 for the location of the chassis intrusion header. 22

Hardware Management Features
The hardware management features of Intel Desktop Board DP43BFL enable the board
to be compatible with the Wired for Management (WfM) specification.
The board has
several hardware management features including the following:
•
Fan speed monitoring and control
•
Thermal and voltage monitoring
•
Chassis intrusion detection
Fan Speed, Thermal, and Voltage Monitoring and
Control
Features of the board’s fan speed, thermal, and voltage monitoring and control
subsystem include:
•
Monitoring of power supply voltages to detect levels above and below acceptable
values.
•
Smart fan control provided by the legacy I/O controller, delivering acoustically-
optimized thermal management.
Fan speed controllers and sensors are integrated
into the legacy I/O controller.
•
Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed according to thermal conditions.
•
Two thermal sensors (processor and a remote thermal sensor).
Chassis Intrusion
The board supports a chassis security feature that detects if the chassis cover has
been removed.
The security feature uses a mechanical switch on the chassis that can
be connected to the chassis intrusion header on the Desktop Board.
See Figure 22 for
the location of the chassis intrusion header.
