Air Flow
Air flow is from the front (through the fans) to the back of the rack frame.
NOTE: Please make sure that the ventilation holes at the top and the rear edge are not
covered.
Additional ventilation holes are provided left and right of the rack frame to allow for some
airflow if the front cover is open or removed. A fan in the back of the rack frame supports
this additional airflow.
This additional fan can easily be replaced from the back of the rack frame.
