That is in reference to the airflow of the fans. Here is some additional information: http://dell.to/2pdKmUa
"Architectural features to optimize data center network flexibility, efficiency and availability include IO panel to PSU airflow or PSU to IO panel airflow for hot/cold aisle environments and redundant, hot-swappable power supplies and fans."

As Daniel have mentioned, it refers to the airflow of the FAN. In the PSU to IO, the air will flow from the power supply unit (PSU) to the IO panel, this is the common setup in a ToR, because the PSU will face the front of the cabinet rack.

Hi!
I have IO-to-PSU FANs and PSUs installed at the moment. I have bought the PSU-to-IO FANs and PSUs. Is it possible to change them while not turning off the switch?
Thanks!
