Airflow	Back to front (toward ports) using port-side exhaust fans Front to back (into ports) using port-side intake fans 50 CFM (0.02 m³/s) through system fan assembly at 25°C 100 CFM (0.04 m³/s) maximum We recommend that you maintain a minimum air space of 2.5 in. (6.4 cm) between walls and chassis air vents and a minimum horizontal separation of 6 in. (15.2 cm) between two chassis to prevent overheating. To prevent the switch from overheating and shutting down, you must position the air intake for the switch in a cold aisle.
