The sensors must be installed where lack of sufficient cooling air is most likely. The optimum position of the rack temperature sensors will vary from installation to installation, but should be located in the airflow to allow accurate readings.

Servers most likely to have insufficient air or inadequately hot air from the hot aisle include:
