If there is the same number of cabinets on the two sides of an air conditioner (as shown by air
conditioner 3 in Figure 15-74 and Figure 15-75), preferentially deploy a T/H sensor to the cabinet on the
left side of the air conditioner.
2. Assign the second T/H sensor to the cabinet furthest from the other side of the air
conditioner, as shown by (2) in Figure 15-74 and Figure 15-75.
3. Assign the third T/H sensor to the cabinet that is between the first T/H sensor and the air
conditioner and near the air conditioner, as shown by (3) in Figure 15-74 and Figure
15-75.

15.8 Installing a Temperature and Humidity Sensor
A temperature and humidity sensor collects the temperature and humidity data of the front and
rear doors of IT cabinets. The air conditioner controls the temperature and humidity in the
aisle containment based on the data collected by the temperature and humidity sensor.
Prerequisites
In the smart module scenario, the supply-air control and return-air control of the air conditioner are not
recommended. If a cold aisle containment is configured, it is advised to adopt cold aisle control; if a hot
aisle containment is configured, it is advised to adopt hot aisle control.
Term description
Supply-air control by an air conditioner: The air conditioner controls the temperature at
its front door so that the temperature is close to the temperature set on the air conditioner.
