Inspect the router redundant cooling system components to ensure that air is flowing
through the router to cool the components installed in the router chassis. If the router
temperature exceeds a critical level, the router automatically shuts down.
Redundant cooling system components are more than just one fan or impeller installed
in a router to ensure that the air is flowing through the router and that an acceptable
temperature is maintained to cool the components installed in the chassis.
