LT-IGS3412F8+4 Port Gigabit Industrial Managed Switch (black)

The LT-IGS3412F is a full‑gigabit Layer 2 managed industrial switch developed by NEWBRIDGE® for rugged environments requiring high reliability, fiber connectivity, and advanced ring redundancy. It features 8× 10/100/1000Mbps RJ45 ports and 4× 100/1000Mbps SFP fiber slots – all ports support non‑blocking wire‑speed forwarding. 

This switch does NOT support PoE (data only). Built to operate reliably from -40°C to +75°C using industrial‑grade components and fanless natural heat dissipation, it meets the demands of intelligent transportation, rail transit, power industry, mining, oil & gas, shipping, metallurgy, and green energy.

The IP40‑rated aluminum alloy housing provides excellent heat dissipation and dust protection. The switch supports wide voltage input (12‑48VDC) with triple power redundancy (two sets of V+/V- Phoenix terminals plus one DC input) and includes a relay alarm output for custom condition triggers. It offers comprehensive L2 management features: ERPS (G.8032) ring redundancy with <20ms self‑healing, STP/RSTP/MSTP, IEEE 802.1Q VLAN (port‑based, protocol‑based, MAC‑based, Voice VLAN), QoS (8 queues/port, SP/WRR/SP+WRR), ACL (L2‑L4), IGMP snooping v1/v2/v3, MLD snooping, LACP link aggregation, port mirroring, loop protection, DHCP snooping, and port security. Management interfaces include Web (HTTPS), CLI (Console/Telnet/SSH v2.0), and SNMP v1/v2c/v3.

With 6KV surge protection, extensive EMC immunity (IEC61000-6-2), and a 2‑year warranty, this switch delivers a cost‑effective, stable, and reliable industrial communication network.
