The cooling system consists of the following components:
The airflow produced by these fans keeps router components within the acceptable temperature range (see Figure 15).

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.
