5. Hardware Monitoring
The Intel Server Board SE7500CW2 has an integrated Windbond* 83627HF SIO controller with
integrated hardware monitoring and a MAX6651 controller both of which provide basic hardware
monitoring capabilities. These controllers use the I
2
C bus to communicate to all the sensors
integrated on the baseboard.
Below is a table of monitored headers and sensors on the Intel Server Board SE7500CW2.
