See “Cooling System and Airflow in ACX5448, ACX5448-D, and ACX5448-M Routers” on page 47 for more information about the airflow through the chassis. If you are mounting an ACX5400 router in a rack or cabinet with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
