To introduce cool air into enclosures on a raised computer floor, provide an air
outlet grate in front of the rack (recommended) (see Figure 23) or have the air enter
through the bottom of the rack. Both methods work well, as long as proper airflow is
engineered into the system and adequate air is provided to equipment intakes.
