This means the IOS file the switch is attempting to load is corrupt.

[mohammad saeed]

How to solve it. How did that happened? the switch was stacked and suddenly happened!

[Leo Laohoo]

You will need to re-install the firmware using a USB thumb drive (or xmodem).

[mohammad saeed]

Can I take the IOS image from any switch 2960x with same image and boot it in damage switch?

Thanks

[Leo Laohoo]

Yes.

[mohammad saeed]

Yes I tried to boot a new file from USB and booted successfully! Do I need now to copy a new file inside switch flash?

Thanks

[Leo Laohoo]

Copy? No.
Go to the Cisco website and download the TAR file. Use the command "archive download-sw /overwrite usbflash0:filename.tar".

[mohammad saeed]

I did it with TFTP and now works fine thanks for support
