Firmware downgrade after replaced a stack

Hi All

Something weird happened to me after have replaced a slot within a stack.

The next day I got an alert on my monitoring tool that the firmware of the whole stack downgraded from from 2.0.2.3 to 2.0.2.1. The stack has 3 from x440-24p .

Is that normal can this be ignored or what do you think?

Thanks a lot in advance!

Nick

Hello Nick,

it is recommended to update/downgrad a replacement switch to the same version as used in the stack before! adding to the existing stack.

See here: https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-replace-a-node-in-a-SummitStack

You now can check if the current software version is equal on all slots in you stack with “show version”.

If the version is equal you can update your stack to your desired software version.
