Space and airflow requirements

Leave at least a 10 cm (4 in) clearance space at the front and back of the server for proper ventilation.

CAUTION:

The server draws in cool air through the ventilation openings on the front side, and expels warm air through the ventilation openings on the rear side. Do not block these openings. Failure to observe this caution will result in improper airflow and insufficient cooling that can lead to thermal damage.
