Sorry, we do not warranty/license any "second hand" equipment, only hardware sold directly from a Ruckus reseller.
Too often, the "second hand" equipment was reported faulty, and replaced with new thru an RMA. Therefore, previous S/N equipment is not supported (was supposed to have been returned/destroyed).
I'd ask for your money back, and buy Ruckus equipment from an authorized reseller (which will come with warranty/licensing).
