Description Specication
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 m

/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.
