Hardware Monitor (Optional)
The optional hardware monitor subsystem provides low-cost instrumentation capabilities. The
features of the hardware monitor subsystem include:
• Support for an optional chassis intrusion connector
• An integrated ambient temperature sensor
• Fan speed sensors that monitor the fan 1 and processor active fan connectors (see Figure 15 for
the location of these connectors on the motherboard)
• Power supply voltage monitoring to detect levels above or below acceptable values
When suggested ratings for temperature, fan speed, or voltage are exceeded, an interrupt is
activated. The hardware monitor component connects to the system management (SM) bus.
