magic number mismatch: bad mzip file in 3750 stack switch

Hi,

The reason you are getting this error message on the switch is a corrupt or wrong IOS image "c3750e-ipbasek9-tar.122-55.SE5.tar".

If the switch is in rommon mode, and you have any other image in the switch, boot it using that image. Once the switch is up, download and copy the correct IOS image once again on the switch and try to upgrade.


If you need help in finding the correct IOS image, give me the exact switch model number, i will help you with that.

But forsure the image is wrong or corrupt and that is why you are getting this error.

Thanks

Ankur
