Ventilation Principle
The ventilation principle inside the cabinet is illustrated in Figure 1-6. A flow of air is
forced by the air guide unit at the lower part of the subrack into the cabinet. After
being blown by the fan unit on the top of the subrack, the cooling air passes upward
through the subracks and is exhausted from the top of the cabinet.
