3.2 Principle of Cooling Operation
Figure 2 Cooling airflow, side view
Air that has been heated by the servers to 95°F (35°C), for example, is circulated to a specially
designed air/water heat exchanger by high-performance fans. The heated air is cooled to 68-77°F
(20-25°C) and fed to the front of the server.
The server fans can draw in the air and feed it over internal components.
Cold water is provided by a separate Liebert XD Pumping unit.
A condensate tray with a 5/8" outlet is below the heat exchanger.
NOTE
If the rear door (with fans) is opened, the front door must be opened. If the front door is opened,
it is not necessary to open the rear door.
