Juniper ACX710 Quick Start Manual page 4

Router Clearance Requirements
For the cooling system to function properly, the airflow around the chassis must be unrestricted. You must allow sufficient
clearance around the installed chassis for cooling and maintenance.
If you are mounting an ACX710 in a rack with other equipment, ensure that the exhaust from the other equipment does
not blow into the intake vents of the ACX710 chassis.
For service personnel to remove and install hardware components, and to accommodate the interface and power cable
bend radius, 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 rear of the router. See

Router Cooling and Airflow Requirements
In ACX710 routers, cool air is pulled through the front of the chassis towards the rear fan tray, and hot air is exhausted
out of the chassis through the rear.
For the cooling system to function properly, the airflow around the chassis must be unrestricted.
The rack or cabinet must have an adequate supply of cool air.
