Has anyone seen the following fan warnings after upgrading the OS on 5548UP? I tested on 2 systems with the same result. Reverting back to NX-OS 5.0 stops the warning. The upgrade was done using the command:
install all kickstart bootflash:n5000-uk9-kickstart.5.1.3.N1.1a.bin system bootflash:n5000-uk9.5.1.3.N1.1a.bin
Same problem for n5000-uk9.5.2.1.N1.bin and n5000-uk9.5.1.3.N1.1a.bin images. No problem running n5000-uk9.5.0.3.N2.1.bin

Thanks.. I had seen similar issue once in the past where N5548P-FAN-B was recognized as N5548P-FAN after an upgrade causing the error. I suggest that you open a TAC case and get the fans replaced to see if it helps. If you open a TAC case, do let me know the case number so that I can follow up with it.

Managed to fix the problem. I had to replace both powersupplies and fan modules. It appears the Back-to-Front airflow provided by N55-PAC-750W-B power supply and N5548UP-FAN-B fan doesn't work with NX-OS 5.1 and 5.2. What works is N55-PAC-750W and N5548UP-FAN.

N55-PAC-750W-B power supply and N5548UP-FAN-B fan do work but you will have to replace the
N5548UP-FAN-B modules

From what I can tell, we can't mismatch the FAN and PAC when it comes to the airflow. If I try to put N5548UP-FAN with N55-PAC-750W-B the switch will automatically turn off. Both PS and FAN have to be either Front-to-Back or Back-to-Front airflow. That's why to run NX-OS 5.1 or 5.2 I had to replace both the PSs and the FANs.
Thanks for your help, it pointed me in the right direction.
