1.15 Platform Management and Security
Intel DH61WW Desktop Board integrates several functions designed to manage the
system and lower the total cost of ownership (TCO) of the system. These system
management functions are designed to report errors, diagnose the system, and
recover from system lockups without the aid of an external microcontroller.
1.15.1 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
1.15.2 Hardware Monitoring
The hardware monitoring and fan control subsystem is based on the Nuvoton
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_SM, and +VCCP
• SMBus interface
1.15.2.1 Fan Monitoring
Fan monitoring can be observed through the BIOS setup user interface, Intel
®
Desktop
Utilities or third-party software.

The functions of the fan headers Section 1.16.2.2, page 35
1.15.2.2 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.
