However I have never needed to replace/reseat/add any Nexus line cards since I walked into this Nexus deployment two years ago. (Several power supplies and a fan tray, but no line cards.)
Is replacing (or adding) a line card truly impact-free on the other line cards/traffic that is currently in production?
To test, I have scheduled a downtime for testing to involve replacing one of the line cards and one of the supervisors.
However I was wondering if any of you could give me a heads up on what to expect.
