(Optional) Connecting T/H Sensors
Context
- T/H sensors outside the cabinet are configured to detect the temperatures of cold/hot aisles. They can be flexibly installed on the server cabinet based on site situations. It is recommended that the T/H sensors be deployed near heat sources in the hot aisle, or near places that lack cooling capacity in the cold aisle. Place the T/H sensors on the cabinet adjacent to the smart cooling product without directly facing the exhaust vents of the smart cooling product.
- During installation, reserve cable routes for the T/H sensors.
Procedure
- Connect the T/H sensors outside the cabinet and the T/H sensors at the return air side in series.Figure 4-35 Connecting the T/H sensors
(1) Connecting a T/H sensor outside the cabinet
- The T/H sensors should be 1.5 m above the ground (33 U).
- Each smart cooling product supports a maximum of thirteen T/H sensors.
- Set DIP switches of the T/H sensors.Table 4-6 DIP switch settings
