Hi,

I'm planning to take my stacks icx switch to a new firmware version, but I work from home, cause of Covid 19. How can I do that remotely without scrahing my network?

I would recommend using an on-site TFTP server if you have the option. What code would you be upgrading from/to?

Thanks for replying.

From 0.08.70dt211 to 0.08.90d

Yes I have a tftp server on site. 
But I'm afraid of the behavior of the stack, cause I cannot connect to with a serial cable (out of the office). I will use SSH


Thanks again

Recommendation would be to use 8080f (non-ufi) as an intermediate code. Your upgrade path would look like this:

8070d > 8080f (non-ufi - same format as 8070d) > 8090d UFI (new file format - everything in one file)

Obviously not having console access is a downside should anything arise during the upgrade. That would really be your call on how critical the stack is to your business. I would not expect to have any issues, but you never know. If you would like assistance with the upgrade, I would recommend opening a support case.

To be sure, do you think that from the satck IP management, if I download the code using tftp server on site, the code will be copied automatically to all the stack members and then all the stack members will be upgraded at the same time?

This is my question before proceding with the upgrade job

Correct. Upgrading a single unit vs. a stack is the same procedure. It will copy the files to all the units automatically. However, I always recommend issuing 'show flash' before reloading into the new code so you can double-check the files copied to all units.

Hi, 
Thanks a lot for your help.

So, is it a must that the code be downloaded to the main unit on the stack and then populate to all other stack members?  Cause, when I use ssh to connect via the ip management of the stack, and to load  the code via a tftp server, I don't know it the code will be on the main unit first.

Thanks

You just do the normal "copy tftp flash" command one time. It will automatically transfer to all units. The CLI will show that it is copying to all units and you can use "show flash" to confirm once it is finished.
