Hello,

 

I believe I have a hardware failure but I wanted to check and see if there was a possibitlity it is not.  I have tp-link 10g TL-SM5310-T RJ45 modules in all for SFP ports on the switch.  25 is working fine, 26 does not get a link light or work at all, 27 and 28 are in a static link going to an EAP783.

 

I have tried all of the RJ45 modules in port 26 and none of them work in that port so i do not believe the RJ45 module is the issue.  I have also noticed in the course of investigating the issue that as I plug and unplug from port 26, port 27 often will briefly loose its connection but it comes back.

 

Am I missing something or is it likely that the switch is just bad?

 

Thanks!

Ok, I had not noticed that the switch got a new firmware this week.  I guess I'm dumb for having the auto updates on.  I rolled back the firmware and the problem goes away.
