N9K-C93180YC with mixed airflow direction on PSU and Fans

[Madura Malwatte]

Will the N9K-C93180YC switches work with mixed airflow direction with PSU's being Port Side Exhaust and Fans with port side intake?

We need to get these installed while we wait for the correct PSU's with the port side intake to arrive. Any issues with having mixed airflow direction in the short term (2-3 weeks)?

Nope. You cannot mix the direction of airflow of PSU and Fans.

• The power supply that you are installing must be capable of using the same airflow direction as the fan trays installed in the same switch

Stay safe,
