I don't have a document, but I can tell: it's good stuff
We have 8000 ports or so, on a few dozen 5406 and 5412, and they just don't quit working.
Very good quality and lifetime warranty.
Just perfect.
A reboot and firmware upgrade (if you want) only every 2 years or so, is enough to keep them running smoothly.
Network equipment normally have a life expectancy / lifespan of 5 years.
Half of our chassis still running and are 10 years old...
(The other half was still working in good order)
The last few years, I think 6 PSUs and 8 24port PoE blades failed.
Because we have 2 / 4 PSUs in each chassis, the users are not affected.
After creating a ticket, in one to two days new hardware arrives.
