Maintaining the MX10003 Fan Module
Purpose
For optimum cooling, verify the condition of the fans.
Action
•
Monitor the status of the fans. A fan module 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 when a fan module is removed.
•
To display the status of the cooling system, issue the show chassis environment command. The output
is similar to the following:
user@host> show chassis environment
