Upgrade IOS on stack of two WC-C2960X-48TD-L fail

[amator007]

I need to make upgrade IOS on stack 2 x WS-C2960X-48TD-L, from version 15.0 (2) EX5 to version 15.2.2-E5. I chose the easy way by Cisco Network Assistant (.tar file).

Unfortunately, the upgrade fails with the error. Interestingly, in the column "Device type” CNA reports ... WS-C3750 Stack (?).

What can be the cause of the error?:

1. Upgrade by CNA?
2. Invalid IOS file (for wrong device)?
3. No pay for the IOS file (my provider said, that I have the right to download upgrade file)?
4. Other reason?

Kind regards –

Use the CLI command "archive download-sw tftp://<TFTP IP address>/filename.tar".

Thanks!

Yesterday I watched your presentation and everything became clear. I learned a lot. In addition, I noticed that in my stack 2960X prevailed democracy - both switches have priority 1. It also changed.
