Heat Output, Airflow, and Cooling
The maximum heat output of either model is 330 watts (1126 BTU/hr).
Each 2104 requires an airflow of 1.1 m³ ( 40 cubic feet) 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 is in at the front of the rack and out at the back. To avoid moving exhaust
air to the intake of another piece of equipment, racks should be positioned in
alternate rows, back-to-back and front-to-front.
v The front of racks should be positioned on floor-tile seams, with a full line of
perforated tiles immediately in front of the racks.
v Where racks are in rows front-to-front or back-to-back, there should be a gap of at
least 1220 mm (48 in) separating the rows.
v To ensure proper airflow within each rack, the rack filler plates must be installed in
unused positions. Also, all the gaps in the front of the racks must be sealed,
including the gaps between the 2104s.
