Airflow mode of Cisco Nexus 93180yc FX3

I need to rack and stack Cisco Nexus 93180yc FX3 in my datacenter, therefore, I need to know what airflow mode to choose.

The Nexus 9K datacenter switches support two airflow modes

1. Portside intake - sucks cold air into network ports and blows warm air out of the power supply's  into hot aisle 
2. Portside exhaust - sucks cold air into power supply's and blows warm air out of the ports into hot aisle

The network ports should be located on the same side of the rack as the server’s rear panel, therefore, I need portside exhaust airflow mode.

Hope this helps other IT guys in the field.
