We have 2 S5248F-ON switches. We received them with normal airflow fans/PSU's (red tabs) and swapped them out for reverse airflow (blue tabs).

For some reason they are both giving mixed readings. So for example, switch 1 reads:

PSU 1 - NORMAL

PSU 2 - Reverse

 

FAN 1 - Reverse

FAN 2 - Reverse

FAN 3 - NORMAL

FAN 4 - Reverse

Any ideas why this might be and/or how to troubleshoot?

TIA
