Product Description

ISM7112G-4GF-8GT is a layer 2 gigabit managed embedded switch module with 4 Gigabit fiber ports and 8 Gigabit copper ports. This switch adopts a storage and forward mechanism, with powerful bandwidth processing capabilities, automatically troubleshooting data packet errors, reducing transmission failures, and ensuring stable, reliable, and efficient data transmission. The hardware is a low-power, wide temperature, and modular design, with a compact structure and small size, which is easy to install and maintain. It can flexibly install and customize interface connection methods. It uses industrial grade components, operating at a wide temperature from -40 ℃ to+70 ℃, embedded installation.


The ISM7112G-4GF-8GT follows the main communication standards in the industrial field, meeting technical requests of real-time communication and network security. It provides multiple ways to manage switches, such as accessing the switch command line (CLI) through the CONSOLE port or TELNET/SSH protocol, accessing the switch web interface through HTTP/HTTPS, and accessing the device MIB through the SNMP protocol. It supports multiple network protocols and industry standards, such as MW-Ring, ERPS, STP/RSTP/MSTP, VLAN, GVRP, QoS, LACP, IGMP, IGMP Snooping, GMRP, LLDP, 802.1X,ACL, SNTP, port mirroring, Ping, Tracert, etc. It supports system management such as uploading and downloading configuration files, and upgrading image files online. The product is widely applicable in fields such as comprehensive energy, smart cities, rail transit, intelligent transportation, smart factories, and industrial automation.

Features and Benefits
  1. Support rate limits for broadcast, multicast, and unknown unicast messages, detect broadcast and multicast packet storms, and prevent broadcast storms
  2. Support link static aggregation and dynamic aggregation LACP, which can increase transmission bandwidth, improve link reliability and realize network load balance
  3. Support 802.1Q VLAN, provide Access, Trunk, Hybrid interface easy to divide multiple broadcast domain, enhance the security of the network
  4. Support VLAN division based on port, MAC, protocol, IP subnetwork, etc., which can be applied to networks in different environments
  5. Support GVRP protocol, realize dynamic distribution, registration and propagation of VLAN attributes, and maintain dynamic VLAN
  6. Support the MAC address table and the aging time limit, and the static unicast / multicast MAC address is bound with the interface, to ensure the use of legitimate users
  7. Support IGMP Snooping, GMRP multicast protocol, reduce multicast data broadcasting in the network, and save network resources
  8. Support LLDP link layer discovery protocol, obtains LLDP neighbor device information, monitors link status, facilitates topology management and fault localization
  9. Support ERPS Ethernet multi ring protection technology, provide multi ring networking, perform link backup, achieve fast convergence, and improve network stability
  10. Support EAPS loop protection protocol and MW-RingV2 private loop network protocol, enhance the reliability of system communication
  11. Support STP, RSTP, MSTP generating tree protocol, which can eliminate network loop and improve network reliability
  12. Support loop back detection to prevent the network from ring and causing the network storm
