Cooling System and Airflow in ACX500 Routers
The ACX500 indoor routers do not contain fans, and are passively cooled through air vents. The air vents in the router are located on both the sides of the router and also on top of the router (see Figure 1). Temperature sensors in the chassis monitor the temperature within the chassis. If the temperature inside the chassis rises above the threshold, the router shuts down automatically.
The ACX500 outdoor routers do not contain fans, and are passively cooled by internal heat sinks and external cooling fins (see Figure 2). The external cooling fins on the body of the ACX500 outdoor router help to dissipate the heat. Unlike the ACX500 indoor routers, the ACX500 outdoor routers do not have air vents.
