• Chassis intrusion detection
1.10.1

Hardware Monitoring

The hardware monitoring and fan control subsystem is based on the Nuvoton
NCT67760 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, +V
PCH V
CC
• SMBus interface
1.10.2

Fan Monitoring

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.
