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 airow through
the chassis to ventilate heat. A 5cm clearance is
also required on the front of the chassis.
To ensure normal operation, maintain ambient
airow. Do not block the airow around chassis
such as placing the system in a closed cabinet.
