1. Each 2104 rack-mounted unit requires an air flow of 1.1 cubic meters/minute (40 Cubic feet per minute (CFM)).
When racks containing many 2104 units are to be installed together, the following requirements must be met to
ensure that the 2104 units 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 air flow 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 2104 units.
2. The recommended operating temperature is 22°C (72°F) or lower. At lower temperatures, the risk of failure in the
unit is reduced. If the operating temperature is above 22°C (72°F) for long periods of time, the unit will be
exposed to a greater risk of failure from external causes.
3. See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
