Hello Mhel,
Basically, for any technical support or customer service, you need an active/valid support contract for assistance.
It is also useful in RMAs(replacement) where you get an Advance Replacement in which the new unit will be shipped out in 2 business days.
There are various support contracts for different devices in Ruckus. Please go through the below link for more details.
