2960-x interface error on boot

[LANadmin75]

Hi all,

I have a 4 stack of 2960-x switches that I recently installed and the master switch is displaying the error in the photo on boot. Is the TenGB port bad or could it be the cable? I do have another cable ordered to test. Thanks for any and all assistance!

Resolved. Reverted to a former firmware and the issue went away.

What was the upgraded version?

Release 15.2.6E1 ED
Was the version that caused the issue.

We rolled back to the suggested release, Release 15.2.4E6 MD and the issue was corrected. Why the early release doesn't detect the 10 GB ports is anyone's guess.
