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 143 on page 624 and Table 144 on page 625 describe the redundant cooling system
components and characteristics for each routing platform.
