If you want to load the IOS (BIN file) back to the appliance, then you'll need to read THIS.

magic number mismatch: bad mzip file

Means the IOS you're trying to boot is corrupt:  It failed MD5 hash check.

[+5] to Leo.

The IOS which u have downloaded is corrupt.

After u download it, you can check the integrity by running MD5 checksum utility on PC.You can download FastSum utility by doing google.

You can also run the command verify MD5 in switch to check the same.

Hi dler.mawlod,

Please share that.

 

regds,

aman

catalyst 2960 series 

the reason for asking correct model is that whether u are downloading the correct IOS for switch.
