I can’t remember the exact message, basically when we upgraded about 10 of ours, they wouldn’t let us make any config changes past a certain point because they saw themselves as non genuine even though they are we’ve recently replaced all of our switching, I’ll boot one of them up once I get in and check for you (+IOS version)
I just got my first switch, and I noticed it was manufactured on my first birthday. (i.imgur.com)
