I need your help, I am going to update to the version recommended by Cisco Release 15.2.2E9 MD but I don't know which file to use, if the bin or the tar, what is the main difference, which one should I use?
In general .bin is the base image that you need switch to work. The .tar file also contains this .bin file and an additional set of html & other files that are needed to configure the switch via a web browser.
if you want to simple no over loaded, you can download .bin file and each upgrade.
if you using you need to do archive install.
before upgrade make sure you read the releae notes and supported platforms.

- The .bin file is the Cisco IOS Software image. If you want to use only the CLI to manage the switch, this is the only file you need to download.
- The .tar file is an archive file from which both the IOS image and the CMS files are extracted during the upgrade process. If you want to manage switches or clusters of switches through a web interface (HTML), this is the only file you need to download.
