Description
The EX73900E Series is a DIN-rail mounted Gigabit switch built for mission-critical, harsh-environment installs — rated to operate from -40°C to 75°C where standard networking gear would fail. It combines 8 or 12 RJ45 gigabit ports with up to 4 dual-rate SFP slots and full wire-speed Layer 3 switching, supporting management features like RADIUS/TACACS+ authentication, port security, IGMP snooping, and link aggregation. Compliance certifications cover power substations (IEC 61850-3/IEEE 1613), rail (EN 50121-4), and traffic control (NEMA-TS2) applications.
- Up to 12 gigabit RJ45 ports + 4 dual-rate SFP slots: full wire-speed Layer 3 switching.
- Hardened for -40°C to 75°C operation: designed for high ESD, shock, and vibration environments.
- Advanced management: static routes, RIP v1/v2, OSPF, VRRP, dying gasp, RADIUS/TACACS+ authentication, and port-based VLAN.
- Industry compliance: IEC 61850-3/IEEE 1613 (power substations), EN 50121-4 (rail), and NEMA-TS2 (traffic control).
