The system fan assembly provides cooling air for the internal chassis components. The fan assembly is a tray of fans that you can insert and remove from the chassis while the system is on line. The Catalyst 4503 fan assembly has two fans, the Catalyst 4506 fan assembly has four fans, the Catalyst 4507R fan assembly has six fans, and the Catalyst 4510R fan assembly has eight fans. The fans draw in fresh air from one side and exhaust air on the other side. Catalyst 4503 airflow is shown in Figure 1-13. Catalyst 4506 airflow is shown in Figure 1-14.

Catalyst 4507R airflow is shown in Figure 1-15. Catalyst 4510R airflow is shown in Figure 1-16.

Caution You must install module filler plates on unused switching module slots to ensure proper airflow.
