1.12.1 Hardware Monitor Component
The hardware monitor component provides low-cost instrumentation capabilities. The features of
the component include:
• Internal ambient temperature sensing
• Remote thermal diode sensing for direct monitoring of processor temperature (if supported in
the processor)
• Power supply monitoring (+12, +5, +3.3, +2.5, 3.3 VSB, VCCP) to detect levels above or below
acceptable values
• SMBus interface
1.12.2 Chassis Intrusion Detect Connector
The board supports a chassis security feature that detects if the chassis cover is removed and
sounds an alarm through the onboard speaker. For the chassis intrusion circuit to function, the
chassis’ power supply must be connected to AC power. The security feature uses a mechanical
switch on the chassis that attaches to the chassis intrusion detect connector. The mechanical
switch is closed for normal computer operation.

The signal names of the chassis intrusion detect connector Table 37, page 62
1.12.3 Fan Control and Monitoring
The SMSC LPC47M102 I/O controller provides two fan control outputs and two fan tachometer
inputs. Monitoring and control can be implemented using third-party software.
