1.9 Hardware Management Subsystem
The hardware management features enable the board to be compatible with the Wired
for Management (WfM) specification. The board has several hardware management
features, including the following:
• Fan monitoring and control
• Thermal and voltage monitoring
• Chassis intrusion detection
1.9.1 Hardware Monitoring and Fan Control
The features of the hardware monitoring and fan control include:
• Power supply monitoring of four voltages (+12 V, +3.3 VSB, 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
1.9.2 Fan Monitoring
Fan monitoring can be implemented using Intel Desktop Utilities or third-party
software.
For information about Refer to
The functions of the fan headers Section 1.10.2.2, page 35
1.9.3 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 header. When the chassis cover is removed, the mechanical
switch is in the closed position.
