I tried to upgrade a 2960-8TC-L switch to c2960sm-lanbasek9-mz.150-2.SE10a code but when I attempted to reload the unit, I got the following message on the console:
"File "flash:c2960sm-lanbasek9-mz.150-2.SE10a.bin" uncompressed and installed, entry point: 0x3000
executing...
Error: hardware not supported by firmware.
Try loading newer software instead.
System Resetting..."
At which point, the process would start all over again. I was able to interrupt the cycle using the "mode" button, but when I tried to issue a boot command for the old code, I would get this sequence:
" switch: boot flash:c2960-lanbasek9-mz.122-50.SE5/c2960-lanbasek9-mz.122-50.SE5.bin
Loading "flash:c2960-lanbasek9-mz.122-50.SE5/c2960-lanbasek9-mz.122-50.SE5.bin"...flash:c2960-lanbasek9-mz.122-50.SE5/c2960-lanbasek9-mz.122-50.SE5.bin: invalid argument"
I tried the same command with a "/" after the "flash:" so it was "flash:/" but got the same "invalid argument" result
I also tried to delete the new code from flash, but again got an "invalid argument"
switch: delete flash:c2960sm-lanbasek9-mz.150-2.SE10a.bin
Are you sure you want to delete "flash:c2960sm-lanbasek9-mz.150-2.SE10a.bin" (y/n)?y
File "flash:c2960sm-lanbasek9-mz.150-2.SE10a.bin" not deleted -- invalid argument
How can I correct this and restore the original IOS? Please be specific as I am working through another individual in a city 350 miles away. Thank you
