Notes:
1. Each rack-mounted 2104 Model DU3 requires an airflow of 1.1 m³ per minute (40
ft³ per minute). When racks containing many 2104s are to be installed together, the
following requirements must be met to ensure that the 2104s are adequately cooled:
v The airflow enters at the front of the rack and leaves at the back. To prevent the
air that is leaving the rack from entering the intake of another piece of equipment,
racks should be positioned in alternate rows, back-to-back and front-to-front.
