Giới thiệu
Bộ chuyển mạch Ethernet EX2300 mang đến một giải pháp nhỏ gọn, mật độ cao, hiệu quả về chi phí cho các môi trường mạng nhỏ, nơi không gian và nguồn điện ở mức cao. Với kích thước nhỏ, 1 U, EX2300 hoàn hảo cho việc triển khai lớp truy cập trong các chi nhánh siêu nhỏ, môi trường bán lẻ và nhóm làm việc cũng như truy cập mạng hội tụ trong các mạng lớn hơn.
EX2300 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.
