Thiết bị chuyển mạch thế hệ mới cung cấp kết nối kết nối người dùng với mạng công ty ở quy mô lớn, mạng doanh nghiệp vừa và nhỏ và nhà mạng, sử dụng giao diện Ethernet 1G / 10G.
Thiết bị chuyển mạch hỗ trợ Stacking vật lý, VLANs, nhóm phát đa hướng và các chức năng bảo mật nâng cao.
Hệ thống nguồn cung cấp liên tục Thiết bị chuyển mạch MES2448B có thể được trang pin có thể sạc lại để đảm bảo cung cấp điện trong trường hợp mất kết nối với nguồn chính. Thiết bị cũng được trang bị bộ cấp nguồn cho phép sạc pin khi kết nối nguồn AC. Nguồn điện dự phòng giúp bạn có thể theo dõi trạng thái của nguồn chính và thông báo về việc chuyển đổi loại nguồn.
