I want to upgrade the switch 4010 with file .bin, but in order to avoid any problem during switch boot up I used the boot system command with 2 IOS, first the newest one, and the second IOS current one. The switch booted and come back with the older one.
The command used was:
sdflash:/ie4010-universalk9-mz.152-8.E1/ie4010-universalk9-mz.152-8.E1.bin;sdflash:/ie4010-universalk9-mz.152-7.E2/ie4010-universalk9-mz.152-7.E2.bin
