How to you solve this issue?
The easiest solution, if there is no fancy (i.e. software controlled) way to reverse fan flow:
Just open the switch, unscrew the fans, turn them around and remount them.
Our network engineer did that countless times, and it always works.
No need to spend heaps of $$$ on hardware with the "correct" flow direction.
