Cooling Considerations

The Centellis 2000 provides fault tolerant cooling to front-mounted AdvancedTCA blades and
to rear transition modules based on two intelligent fan trays. Each tray houses two fans, one
pair located at the front, the other at the rear of the shelf. The airflow direction is from front to
rear in the chassis.
The cooling system is able to supply greater than 46 CFM for the front blade and greater than
7.5 CFM for the RTM in each slot.
The actual cooling performance also depends on the slot population and the heatsink design
of the installed blades and should be validated based on the used system configuration.
The cooling system is designed to provide sufficient cooling with a single fan tray at work at
normal operating temperatures of up to 40 °C.
The distance to other equipment must be sufficient to avoid an overheating of the system.
If you install the system into a closed frame, ensure that the air inlet and outlet are kept free.
