Upgrading switch tar IOS file?

[Andy White]

Hello,

I've upgraded the image on some of our switches using the bin files, but how do I upgrade a switch that uses a tar file, it seems I need to expand the file somehow?

Thanks

  Put the tar file on your tftpboot server then on the switch use the "archive download '  command to download the file . This will download the file , extract the file and automatically change  the boot statement .
