Injecting Water to Expel Nitrogen Clean the main pipe beforehand to avoid blockage of the heat exchanger due to foreign construction matter. Close the isolation valve on the water inlet and outlet pipes before the cleaning. 1. Open the general water supply valve. 2.
Installing Cables Connecting the Equipotential Ground Cable and Power Cable 1. When routing the cables, wrap the section of all signal cables inside the smart cooling product with the corrugated pipes and route them out of the corresponding cable holes so that the strong- and weak-current cables are separated.

1. T/H sensors in the aisle should be installed at the door frame inside the server cabinet and 1.5 m above the ground (33 U). 2. T/H sensor and its cable should be purchased from Huawei by BOM number. 3. Connect the T/H sensor outside the cabinet to T/H_2 port. If there are more than one T/H sensors, connect them in series and then connect them to the T/H_2 port.
