However, if you need to convert a QFX5110 to have a different airflow, you can change
the airflow pattern. To convert an AIR IN product SKU to an AIR OUT product SKU or an
AIR OUT product SKU to a AIR IN product SKU, you must replace all of the fans and power
supplies at one time to use the new direction. The system raises an alarm when the
system is converted, which is normal.
