UPGRADE FIRMWARE ON EXISTING STACK (7000 Series) REMOTELY (OUT OF THE OFFICE)

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?

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.
