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:
• Chassis intrusion detection
• Fan monitoring and control (through the ITE 8718F/GX I/O Controller)
• Thermal and voltage monitoring
1.9.1

Hardware Monitoring and Fan Control

The features of the hardware monitoring and fan control ASIC include:
• Internal ambient temperature sensor
• Two remote thermal diode sensors for direct monitoring of processor temperature
and ambient temperature sensing
• Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.5 V, and
+VCCP) to detect levels above or below acceptable values
• Thermally monitored closed-loop fan control, for both fans, that can adjust the fan
speed or switch the fans on or off as needed
• SMBus interface

1.9.2

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.
1.9.3

Fan Monitoring

Fan monitoring can be implemented using third-party software. The level of
monitoring and control is dependent on the I/O controller used with the board.
