For optimum cooling, verify the condition of the fans.
Monitor the status of the fans. A fan tray contains multiple fans that work in unison to
cool the router components. If one fan fails, the router adjusts the speed of the
remaining fans to maintain proper cooling. A red alarm is triggered when a fan fails,
and a yellow alarm and red alarm are triggered when a fan tray is removed.
To display the status of the cooling system, issue the
command. The output is similar to the following:
