1.Route the rack temperature sensor through the hole in either the top or bottom of the unit.

2.Route the sensor through either the top or the bottom of the adjacent server rack.

3.Secure the temperature sensor cable to the front door of the adjacent server rack at multiple locations using the provided wire clips as shown. See “Installation kit” on page 3.

Temperature sensor

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:
