I don’t know why this isn’t plastered on cisco.com, but you can go to here and throw a serial number in and see if it’s affected by the timebomb that hte C2000 CPU’s cause.

If you need to grab your SN, type show inv and it’ll spit out SN and version. I’ve found a bunch of V02 are unaffected, based on that lookup tool.
