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 m ³ ( 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 a...
Page 24
Electrical power electrical power is supplied to each 2104 by either one or two fan-and-power-supply assemblies. These fan-and-power-supply assemblies convert the input voltage to dc for distribution within the 2104. One fan-and-power-supply assembly provides enough power for a fully populated 2104....
