4.9.7 Installing Cables for T/H Sensors Outside the Cabinet

Context
T/H sensors outside the cabinet are installed to detect the temperatures of
cold/hot aisles. They can be flexibly installed on the server cabinet based on onsite
situation. 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. The T/H
sensors outside the cabinet must be near the smart cooling product to sense the
temperature of the outlet air, and must be away from the air exhaust vents of
other smart cooling products.
Procedure
Step 1 Connect one end of a network cable to the unwired port of the T/H sensor on the
air return side, and connect the other end to the T/H sensor outside the cabinet.
Connect the cables in series based on the actual positions of T/H sensors.
