IES7120-14T2F4GS – 20-port managed industrial switch with 2×fiber uplinks and 4×Gigabit SFP

The IES7120-14T2F4GS is a high-reliability, fully managed industrial Layer 2 Ethernet switch equipped with 14× 10/100Base-T(X) copper ports, 2× 100Base-X fiber uplinks and 4× 1000Base-X SFP slots. Designed for medium and large industrial networks, it ensures stable, redundant and secure communication in power utilities, transportation, industrial automation, smart city infrastructure and large-scale CCTV systems.

The combination of Fast Ethernet copper ports with dedicated fiber uplinks enables flexible network topologies and long-distance communication. The Gigabit SFP slots support a wide range of optical modules (SM/MM), allowing users to extend network backbones or uplinks with high bandwidth and high resilience.

The IES7120-14T2F4GS supports comprehensive redundancy protocols such as STP, RSTP, MSTP and ERPS (G.8032), ensuring deterministic and fault-tolerant operation. The integrated Ring mechanism provides ultra-fast recovery times of <20 ms, making the switch suitable for real-time industrial applications where communication continuity is critical.

Advanced Layer 2 management features include IEEE 802.1Q VLAN, QoS, IGMP Snooping, LLDP, LACP, DHCP Server, DHCP Snooping, ACL security and 802.1X authentication. Integrated Modbus TCP monitoring enables real-time supervision from SCADA or control platforms, providing insight into device status, temperature, link quality and event logs.

The device includes extensive diagnostics tools such as Ping, Traceroute, Cable Test, Port Mirroring and SFP DDM, significantly improving maintenance efficiency. A robust security suite—SSH, HTTPS, RADIUS and TACACS+—ensures safe access to configuration interfaces.

Designed for harsh industrial environments, the IES7120-14T2F4GS features a rugged IP40 metal enclosure, fanless cooling and wide operating temperatures from −40…75°C. Its EMC immunity meets IEC 61000-4 requirements, including ±15 kV ESD, ±4 kV EFT and ±4 kV surge protection, making it suitable for high-interference electrical environments and critical applications.
