Upgrading Cisco 3750 switch stack with bin file

    does anyone has any idea to go about upgrading the ios for a 3750
    switch stack using binary file? Cisco website has only instructions for
    using tar file to upgrade. I have tried the conventional way of copy
    the new bin file into both flash1 and flash2 and changing the boot
    config to boot with the new image. But when I rebooted the stack, only
    the master switch is upgraded and the 2nd was not able to join the
    stack as the master detected a version-mismatch.
    Reason for using bin file instead of tar file is because I do not need
    the CMS in our environment.

    Any advice will be greatly appreciated.

    I haven't upgraded using just the bin file - but it should work the
    same... You only have to copy the software to switchA (Master). It is
    responsible for automatically upgrading the other switches in that

    I think somewhere down the line when trying to manually copy the
    software to both switches - something got confused...

    fyi - You can use the .tar file and disable the web interface portion
    by using 'no ip http-server' in your configuration

    Thanks Scott!

    Yes, I was expecting the Master Switch to auto upgrade the 2nd switch
    after the reboot but it didn't. The tar file includes the CMS which I
    feel it is a waste of Flash space if I not going to use it. And also if
    I use a tar file, I can't possibly keep both old and new versions since
    the flash size is only 16MB.
    I believe there should be a way to upgrade it using the binary file
    since it is available in the CCO for download.

    Anyway, thanks again for your help!
