Hi Ricardo,
I'm not sure if the regulations are just for Germany - but I assume, they are worldwide.
If you buy a Extreme Networks Appliance (e.g. IA-A-20) you have to buy at least 1 year support. With that you get a service-contract running the amount of years you purchased. If the service expires you can buy the service for a new amount of years while the appliance is still not "out of support"
You find the End-of-Life list here:

If your product is not end-of-life / end-of-support but is not under a valid service-contract or you are just not sure - contact your Extreme Networks Partner.
Regards
Michael
