Hi, thanks for the feedback. We haven't updated anything and initiated the replacement of the box.

Unless you just updated the boot loader, I would bet on hardware failure.

I wasn't able to find bug id that would indicate an IOS bug (but my search skills may have failed me). https://supportforums.cisco.com/discussion/13092381/cisco-switch-2960-x-seri es-error <https://supportforums.cisco.com/discussion/13092381/cisco-switch-2960-x-seri es-error> I need to check with TAC, but from your point of view, does it look more like a hardware failure or a potential IOS bug?
