Brand New Ie-3300-8t2s-E Modular Switch with 8 Ge Copper and 2 Ge Network Essentials Enterprise Switches Catalyst Ie3300

Industrial grade design, adapt to harsh environment  Wide temperature operation: -40℃ ~ 75℃, adapt to extreme temperature environments (e.g. outdoor, factory, substation).  Fanless heat dissipation: passive heat dissipation design reduces failure points and improves long-term stability.  Anti-interference capability: Comply with industrial standards such as IEC 61850-3 (electric power) and EN 50121-4 (rail transport), anti-electromagnetic interference (EMI), vibration and dust.  Protection level: IP30 protection, suitable for cabinet or industrial control box installation. Port Configuration (8T2S = 8 Gigabit electrical ports + 2 SFP optical ports)  8 Gigabit electrical ports (10/100/1000Base-T): Supports standard Ethernet connection for PLC, HMI, sensors and other devices. Does not support PoE power supply (if PoE is required, select model IE-3300-8P2S-E).  2 Gigabit SFP optical ports: Supports hot-swappable SFP modules (e.g. 1000BASE-SX/LX), flexible selection of multi-mode or single-mode fibre to extend transmission distance (up to 80km). Can be used for uplink connection or redundant networking. Highly Reliable Network Architecture Redundant Protocols: Cisco Resilient Ethernet Protocol (REP): ring redundancy, failover time <50ms. RSTP/MSTP: Prevent network loops and improve 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.
