Cooling System and Airflow in an ACX1000 and ACX1100 Router

The router does not contain fans and is passively cooled by the heatsinks (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.
