Fan trays are mounted in the shelf top. The figure below shows the general airflow for the
system.
The Cooling subsystem is compliant to CP-TA B.4. The cooling system provides for greater than
40 CFM for the front blade and 5.0 CFM for the RTM.
The actual cooling performance depends on the slot population and the heat sink design of
installed blades and should be validated based on the used system configuration.
The cooling subsystem is designed to provide 31.1 CFM in the front and presence of any single
cooling failure.
