“Specifications.”
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-E fan assembly has two fans and the Catalyst 4506-E fan assembly ha s four fans, the
Catalyst 4507R-E fan assembly has eight fans, and the Catalyst 4510R-E fan assembly has ten fans. The
fans draw in fresh air from one side and exhaust air on the other side. Catalyst 4506-E airflow is shown
in Figure 1-12, the others in the series are the same direction.
Caution You must install module filler plates on unused switching module slots to ensure proper airflow.
