Cabinet Requirements For Acx5400 Routers - Juniper ACX5448-D Hardware Manual

For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
"Cooling System and Airflow in ACX5448, ACX5448-D, and ACX5448-M Routers" on page 47

and power cable bendradius, there must be adequate space at the front and rear of the router. Allow at
least 24 in. (61 cm) of space both at the front and the rear of the router.
