Mx10016 Cooling System And Airflow - Juniper MX10016 Hardware Manual

The MX10016 cooling system components work together to keep all components within the acceptable
temperature range. If the maximum temperature specification is exceeded and the system cannot be
adequately cooled, the Routing and Control Board shuts down some or all of the hardware components.
