Perforated Floor Tiles
The default installation for the system assumes a slab floor, but if you install the server on a
raised floor, use perforated tiles in front of the rack to supply cold air to the system. Each tile
should support an airflow of approximately 400 CFM.
Perforated tiles can be arranged in any order in front of the rack, as long as cold air from the
tiles can flow into the rack.
The following is the recommended number of floor tiles:
Rack Number of Tiles
Full rack 6
Half rack 4
