Giới thiệu
Bộ chuyển mạch Ethernet EX3400 là giải pháp tiết kiệm chi phí cho các mạng truy cập dữ liệu, thoại và video doanh nghiệp hội tụ đòi hỏi khắt khe nhất hiện nay. Các thiết bị 1U nhỏ gọn, cấu hình cố định cung cấp các mức hiệu suất và quản lý trước đây chỉ có ở các công tắc truy cập cao cấp.
EX3400 cloud-ready và hỗ trợ ZTP, vì vậy nó có thể được tích hợp, cung cấp và quản lý bảo đảm bằng dây, để mang lại trải nghiệm tốt hơn cho các thiết bị được kết nối.
