The cooling system includes a fan on the rear of the Routing Engine's processor and a fan on the power supply.
The airflow produced by these fans keeps router components within the acceptable temperature range (see Figure 6). The speed of the fan at the rear of the processor is adjusted automatically according to current temperature.

The Routing Engine monitors the temperature of the router components. If the ambient maximum temperature specification is exceeded and the router cannot be adequately cooled, the Routing Engine shuts down the hardware components.
