Airflow Direction Requirements

Summit switches are available in models with the following ventilation airflow direction:

• The air flows from front to back. In these switch models, the fan modules are labeled Air Out.
• The air flows from back to front. In these switch models, the fan modules are labeled Air In.

X465 switches are available with front-to-back airflow. In this switch, the fan modules are labled Air Out.

All installed fan modules must blow air in the same direction and must match the airflow direction of the installed power supplies.
