I upgraded a C2960X-48-FPS-L switch to the latest IOS and get this error. I uploaded different IOS and same error. I factory reset the device and same error.

This could be a bug, but I did not find one.  I would try downgrading the switch to the next version below.

it is a bug, but i have down graded several times, and factory reset to defaults. and no matter which IOS i have on it now it always comes up with the same error

Did you delete the new IOS from flash? Verify that the old IOS is booting? Just making sure.

[Steveosh72]

yes, apparently there is a patch type thing that will fix this. it was a bug with the original IOS that was installed when it was manufactured.

just waiting for where we bought our switches to relay this patch  or fix.
