I am looking for the enclosure screw specifications for the ICX 7250 so I can purchase additional screws. I couldn't find the information in the documentation. Does anyone know what the specifications are? In addition, is it a specialty screw that I need to purchase directly from Ruckus? If so, how would I go about purchasing? Just fyi, the screw is not for the rack ears. They are the smaller ones for the enclosure itself. Thank you for your help.
