    Redundant Cooling System Components Overview

    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.

    Table 1 and Table 2 describe the redundant cooling system components and characteristics for each routing platform.
