3.2.8 Airflow Requirements
The AXP1440 provides fault tolerant cooling to front-mounted AdvancedTCA blades and to
rear transition modules based on one front and one rear maintainable intelligent fan trays with
six fans per tray.
Fan trays are mounted in the shelf top and bottom. The figure below shows the general airflow
for the system.
NOTES: 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 configuration.
The distance to other equipment must be sufficient to avoid an overheating of the
system.
The cooling subsystem is designed to provide 31.1 CFM in the front and presence of
any single cooling failure.
