Airflow Recommendations - Alcatel-Lucent OmniSwitch 6900 Hardware User's Manual

Mounting the Switch

Airflow Recommendations

To ensure proper airflow, be sure that your switch is placed in a well-ventilated area and provide minimum
recommended clearance at the front, back and sides of the switch, as shown below. Restricted airflow can
cause your switch to overheat, which can lead to switch failure.
Note. Clearance is not required at the top and bottom of the chassis.
The OmniSwitch 6900 fan tray is located at the rear of the switch and draws air through the intake vents
located at the top-front of the chassis. The air is directed straight through the chassis' module compart-
ment and past the switch's circuit boards. Airflow is then exhausted through the fan tray vent.
