Industrial Ethernet 3000 Switches Ie-3200-8p2s-E & Ie3400 with 8ge Poe/Poe+ 8t2s-E on Sale

Industrial grade design, adapt to harsh environment Wide temperature operation: -40℃ ~ 75℃, adapt to extreme temperature environments (e.g. outdoor, factory, substation). Fanless cooling: passive cooling design reduces failure points and improves long-term stability. Anti-interference capability: Comply with industrial standards such as IEC 61850-3 (power), EN 50121-4 (rail transport), anti-electromagnetic interference (EMI, vibration, dust. Protection level: IP30 protection, suitable for cabinet or industrial control box installation. 2. Port Configuration (8P2S = 8 PoE+ ports + 2 SFP optical ports) Gigabit PoE+ electrical ports (10/100/1000Base-T): Support IEEE 802.3at PoE+, maximum power supply 30W for single port, can power IP camera, wireless AP, industrial phone and other devices. Intelligent power management, support PoE power budget (need to match with high-power power module). Gigabit SFP optical ports: Supports hot-swappable SFP modules (e.g. 1000BASE-SX/LX), flexible choice of multimode or single-mode fibre to extend transmission distance (up to 80km). Can be used for uplink connection or redundant networking. High-reliability network architecture Redundant protocols: Cisco Resilient Ethernet Protocol (REP): ring redundancy, failover time <50ms. RSTP/MSTP: Prevents network loops and improves reliability. Dual power input: Supports 12~48V DC or 24V AC redundant power supply (optional redundant power module required). Industrial protocol support: Modbus TCP, DNP3, IEC 61850, suitable for power, transport and other industries.
