Context
If one smart cooling product controls multiple T/H sensors, set the DIP switches on
the sensors to specify their communication addresses that uniquely identify these
sensors. Figure 3-65 shows an T/H sensor.

● Secure the weak-current cables, such as the power cable and signal cable, of
the T/H sensors using cable ties.
● T/H sensors outside cabinets are
congured to detect the temperature and
humidity of cold and hot aisles. The T/H sensor can be exibly installed on a
server cabinet based on site requirements. It is recommended that T/H sensors
be deployed near heat sources in the hot aisle, or near places which lack
cooling air in the cold aisle.
Procedure
Step 1 Connect the T/H sensor outside the cabinet and the T/H sensor at the return air
side in series, as shown in Figure 3-66.
