1.10 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:
Thermal and voltage monitoring
•
Chassis intrusion detection
•
1.10.1

Hardware Monitoring

The hardware monitoring and fan control subsystem is based on the Nuvoton
NCT6776D 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, 3.3 Vstandby, V_SM, +VCCP, and
•
PCH V
CC
• SMBus interface
1.10.2

Fan Monitoring

Fan monitoring can be implemented using Intel
software.

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.
