If you are not sure which version of software you are running on your 128T, you can find out by logging in to your GUI for your 128T conductor or router. Once logged in, you just go to the User menu in the top right corner (the menu that appears when you click on your username) and select "About."

As you can, see my Release Version is 3.2.2, which means I will want to look for documentation and training in the community related to version 3.2.

Now, if you are logged in to a 128T conductor, you can use that to check on the software version of the 128T routers being managed by that conductor. To do this, just go to the Admin Central menu and click on Assets. 

You'll see the routers being managed by this conductor listed in the column on the left. If you click on one of the routers, you can see what version of software it is running.
