Fan module (cooling module)
Five of the ten fan modules (cooling modules) of the 3U, 120 (2.5-inch) DAE are located
(Figure 76) on the front. Cooling is provided by these front fan modules and the five fan
modules located in the mid-section of the DAE
modules are installed or removed with the DAE pulled out of the cabinet (for information
