What will occur if power modules or fan modules used on a CE switch have different airflow directions

Description
What will occur if power modules or fan modules used on a switch have different airflow directions?
Solution
If power modules or fan modules used on a CE switch have different airflow directions, the system reports alarms about inconsistent airflow directions of the power modules and fan modules. Inconsistent airflow directions between power modules, fan modules, or between power modules and fan modules degrade system reliability when the switch needs to work in a high-temperature environment for a long time, and shorten service life of the switch.
