LT-IGS3412FP 8+4 Port Gigabit Industrial Managed PoE Switch(black)
The LT-IGS3412FP is a full‑gigabit Layer 2 managed industrial PoE switch developed by NEWBRIDGE® for demanding harsh environments requiring high power PoE, fiber connectivity, and advanced ring redundancy. It features 8× 10/100/1000Mbps PoE+ ports (IEEE 802.3af/at, up to 30W per port) and 4× 100/1000Mbps SFP fiber slots – all ports support non‑blocking wire‑speed forwarding.With a total PoE budget of 240W (requires 50‑57VDC input), it can power multiple IP cameras, wireless APs, or other PoE devices simultaneously. Built to operate reliably from -40°C to +75°CUsing 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. PoE management includes per‑port power allocation, priority setting, time scheduling, and real‑time monitoring. 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 3‑year warranty, this switch delivers a cost‑effective, stable, and reliable industrial communication network.
