Intel Desktop Board DX79TO Technical Product Specification 1.11 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 1.11.1 Hardware Monitoring and Fan Control The hardware monitoring and fan control subsystem is based on the Winbond W83677HG-I device, which supports the following: • Processor and system ambient temperature monitoring • Chassis fan speed monitoring • Power monitoring of +12 V, +5 V, +3.3 V, V_SM1, V_SM2, 3.3V_Standby and +VCCP • SMBus interface 1.11.2 Fan Monitoring Fan monitoring can be implemented using Intel® Extreme Tuning Utility, Intel® Desktop Utility, or third-party software. For information about The functions of the fan headers Refer to Section 1.12.2.2, page 34 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 header. When the chassis cover is removed, the mechanical switch is in the closed position.

1.11
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
1.11.1
Hardware Monitoring and Fan Control
The hardware monitoring and fan control subsystem is based on the Winbond
W83677HG-I device, which supports the following:
•
Processor and system ambient temperature monitoring
•
Chassis fan speed monitoring
•
Power monitoring of +12 V, +5 V, +3.3 V, V_SM1, V_SM2, 3.3V_Standby and
+VCCP
•
SMBus interface
1.11.2
Fan Monitoring
Fan monitoring can be implemented using Intel
®
Extreme Tuning Utility, Intel
®
Desktop Utility, or third-party software.
For information about
Refer to
The functions of the fan headers
Section 1.12.2.2, page 34
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 header.
When the chassis cover is removed, the mechanical
switch is in the closed position.
