I have seen your company’s products from web site. And I want if you can answer the following questions. I’m trying to design a network using two products from Zyxel. XGS2210-52 / XS1920-12 Is there any problem to connect to XS1920 RJ45 using SFP-10G-T-ZYX on XGS2210 SFP+? any compatibility issues with the product? Please reply as soon as possible.
