Page 13: Description
If this system can not deliver the airflow required by the servers to where it is needed, the floor tile can be replaced by an Air Booster 2. The reasons for an adjustment of the air supply can be caused for example by changes in the configuration of the rack (conversion to high density racks) or by changes in the raised floor which lead to pressure drops which were originally not calculated. - Page 14 Three temperature sensors have to be installed in the high part, the middle and in the lower part of the rack. The fan speed of the Air Booster 2 is proportional to the average temperature of the three temperature sensors of the rack, or is proportional to the maximum temperature detected from the sensors, according to the controller settings.
