Please find attached a small spreadsheet that helps in determine the maximum hours a device may have been powered on.
Nothing particularly useful, the only use case would be if you are shopping for used devices on e-bay or similar (when in the photos the MAC is readable).
Let's say that you find a listing for a RB3011 with MAC beginning with B8:69: F4 for 75 € and one with a MAC beginning with 6C:3B:6B for 65 €, both visually looking fine.
The first cannot have more than 70.000 hours or so.
The second cannot have more than 90.000 hours or so. (it is possibly two years older than the first)
Which one would you buy?
