Do Not Install Components with Different Airflow or Wattage in the Switch
Do not mix airflow direction on fans or power supplies. You can use the color-coding on fan and power
supply handles to ensure the airflow direction matches. The handles on Airflow In fans and power supplies
are azure blue, compared to the Airflow Out fans and power supplies, which are Juniper gold.
Mixing components with different airflows in the same chassis hampers the performance of the cooling
system of the switch and leads to overheating of the chassis.
