Intel Desktop Board DQ67EP Technical Product Specification

1.15 Platform Management and Security

In addition to Intel AMT the Intel DQ67EP 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
Utilities or third-party software.

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.
