        48G+4*10G port layer 2 managed rack mountable switches
        Product Overview

        SICOM3448G is a full Gigabit layer 2 managed industrial Ethernet switch designed to operate reliably in climatically demanding utility and industrial environments. SICOM3448G is a 19-inch 2U rack mountable device, supports 4 10gigabit ports + 20 gigabit combo ports + 28 gigabit copper ports, or 4 10gigabit ports + 8 gigabit combo ports + 24 gigabit SFP ports + 16 gigabit copper ports. SICOM3448G supports many Layer 2 software features such as port, VLAN, multicast, QoS, fast redundant ring. It supports Console, Telnet, Web management and network management software based on SNMP. At present, the product is widely used at the oil & gas, distribution network automation and many other industrial communication systems.
