3.2.2.3 DM1904 Ventilation
The airflow of the DM1904 Chassis flows from the front to the back. The servers that are inserted in the
front side and the power supplies that are inserted in the rear side of the DM1904 Chassis provide their
own cooling system, with cold air being drawn in the front side and hot air blowing out of the rear side.
It is essential for the correct functioning of the whole cooling system that all ventilation inlets and outlets
are unobstructed and that free space of at least 10cm on the front and rear panels are respected.
