Device: C2960-24PS-LL
IOS Image to be loaded: c2960x-universalk9-mz.152-7.E5.bin
Have copied the file to flash, and it is listed. 


"Switch: Boot " returns the following:

Not going to work.

The switch is a plain 2960 but the IOS is meant for 2960X.  It won't work.

And stop "upgrading" the IOS by using the incorrect method of "copying" the BIN file from one platform to another. 

If someone had used the "archive download-sw" the script would have stopped and warn the operator of incompatible platform.

Many thanks for your input, do you mean COPY USBFLASH0: FLASH: is incorrect??

Look what happened when someone copied the wrong IOS.  The switch did not boot it and went into ROMMON.  Blindly copying the BIN file from one platform to another is inviting a disaster. 

The script command "archive download-sw" minimizes the chance of unpacking the IOS into the wrong platform or model.
