We have noticed that in two of our Unifi Switches ( 48 POE-500W) it shows RX fault as the status in the SFP port in the controller.
The controller firmware is 5.7.23 and the firmware version of the switches are 22.214.171.12487. We have noticed that there is pending firmware upgrade for switches (into 126.96.36.19952). Please let me know will it fix after a firmware upgrade.
How to identify whether this is a hardware failure of the SFP module or due to the firmware. Because this alert did not occur throughout the existing firmware.

Are you able to test another interface on your switch? Did you confirm that the pairs weren't reversed?
You could cat /var/log/messages from the switch.
