Heat output, airflow, and cooling
The maximum heat output of the FAStT100 is 390 watts (1088 BTU/hr). Each
FAStT100 rack-mounted unit requires an airflow of 2.5 m
input air temperature to all racks should be in the range 10° C - 35° C (50° F - 95°
F). The recommended operating temperature is 22° C (72° F).
When racks that contain many FAStT100s are to be installed together, the following
requirements must be met to ensure that the FAStT100s are adequately cooled:
v Air enters at the front of the rack and leaves at the back. To prevent the air that
