Front-to-Rear Airflow
The OmniSwitch 6900 fan tray and power supplies are located at the rear of the switch and draw air
through the intake vents located at the top-front of the chassis. The air is directed straight through the
chassis’ module compartment and past the switch’s circuit boards. Airflow is then exhausted through
their vents.
