Alcatel-Lucent 6624 Chassis Airflow, Right Side Air Intake Vent, Left Side Fan Exhaust Vents

OmniSwitch 6600 Series Chassis and Hardware Components Temperature Management

Chassis Airflow

The fans pull air from the air intake vent located at the right-hand side of the chassis. The air is directed horizontally through the chassis and past the circuit board and uplink and stacking modules (if installed). Airflow is then exhausted through the fan vents at the left-hand side of the chassis. Refer to the illustra- tions below for more information.

2.Airflow. The air from the intake vent is directed through the chassis past the

main circuit board and sub- module daughtercards. This airflow provides required cooling for these chassis com- ponents.

3. Air Exhaust. The airflow
is exhausted through the fan
exhaust vents at the left-hand
side of the chassis.	Fan Exhaust Vents

Important. Maintain a clearance of at least two inches at the left and right sides. Otherwise, airflow may become restricted. Restricted airflow can cause your switch to overheat; overheating can lead to switch failure.
