IMPORTANT:
It is important to leave a clearance of 10cm to
the rear side of the chassis. The clearance is
required to ensure an adequate airflow through
the chassis to ventilate heat. A 5cm clearance is
also required on the front of the chassis.
To ensure normal operation, maintain ambient
airflow. Do not block the airflow around chassis
such as placing the system in a closed cabinet.
