SICOM2024M is a layer 2 managed industrial Ethernet switch designed to operate reliably in electrically harsh and climatically demanding utility substation and industrial environments. SICOM2024M supports up to 4 fast Ethernet fiber ports and 24 fast Ethernet RJ45 ports, meets the IEC61850 and IEEE1613 standards. SICOM2024M is a 19-inch 1U rack mountable device and allows front and rear panel mounting. It supports many Layer 2 software features such as port, VLAN, multicast, QoS, RSTP. It supports Console, Telnet, Web management and network management software based on SNMP. At present, the product is widely used at the intelligent substation and many other industrial communication systems.
