S5248F-ON switch airflow issue
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

Hello TazMan90,
Have you tried reseating PSU1 and Fan 3?
Lets get a look at the part numbers. Can you post the output of:
#show inventory
Are you up to date on firmware and OS?
Could you post
OS version:
Firmware version:
If you have a maintenance window you could - shut down, swap power supply slots and swap fan 3 with another fan and check results if issue follows or stays in slot.
