the installation guide.
Step 2 Ensure that the equipment in the cabinet is deployed evenly, and all vacant U
spaces are sealed with filler panels.
Step 3 Ensure that the aisle doors and skylights of the smart module are closed to isolate
the cold aisle containment from the hot aisle containment and prevent hot air
backflow.

No filler panels have been installed for the vacant U spaces in the cabinet.
The cold and hot aisle containments of the smart module are not isolated,
which causes hot air backflow.
