Cooling System and Airflow in ACX7024 Routers
The cooling system in an ACX7024 router consists of six system fans. Figure 1 shows the fans in an ACX7024 router.

The ACX7024 routers support only front-to-back airflow (airflow out or AFO). In AFO models, the device pulls in airthrough the front of the chassis toward the system fans, from where it exhausts the air out of the chassis. Figure 2 shows the airflow direction in an ACX7024 router.
Note:
Leave at least 6 in. (15.2 cm) clearance each at the front and rear of the chassis for airflow and to accommodate the interface and power cable bend radius.
