N3024 10Gb ports crashing

Question

I have two stacked N3024 switches and have suffered three front panel 10Gb ports which have initially worked fine but then subsequently gone dead requiring repowering of the switch stack to recover. I understand that unsupported SFP+ modules may or may not work, however this is the first time I have had to repower a switch to recover a port. The fourth 10Gb port and all four on the expansion modules have never given a problem. Is this a known problem and is there a way to recover the ports without repowering?

I looked through the CLI guide, but I didn't see an option to do this. The only thing I'm seeing that might accomplish something similar would be to shutdown the interface, then bring it back up. I'll link to the CLI guide below

As for this being a known issue, it isn't something that I've encountered before, but I wouldn't necessarily rule out entirely. Other than trying to restart the interface, the only thing that I can think to recommend would be to use supported SFP modules.

I found that the only way to recover the ports was to repower the switches. All three failed ports came back to life. I have now fitted a Mellanox SFP+ (also unsupported) in place of the Finisar unit.
