5.5.2 Handling Long-time Hotspot at the Air Inlet of a Cabinet

in iCooling Mode

Symptom

There is a hotspot (higher than 27°C) at the air inlet of a cabinet in iCooling mode

for more than 2 hours and the hotspot persists.

Possible Causes

● The cabinet temperature sensor is installed at an incorrect position.

● No ller 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 backow.

Procedure

Step 1 Ensure that the cabinet temperature sensor is installed at the position specied in

the installation guide.

Step 2 Ensure that the equipment in the cabinet is deployed evenly, and all vacant U

spaces are sealed with ller 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

backow.

Step 4 Check whether the cabinet temperature sensor is faulty. If so, replace it.
