EX78900X Series
EtherWAN’s EX78900X Series is a rugged, DIN-rail mounted managed PoE switch designed for industrial and mission-critical networks. It offers up to 12 Gigabit PoE ports with IEEE 802.3bt support, delivering up to 90W per port and a 360W total power budget, plus 4 tri-speed 1G/2.5G/10G SFP+ uplinks for high-bandwidth fiber connectivity. Certified for Class I, Division 2 hazardous locations, the series is ideal for deployment in industrial automation, energy, transportation, and other demanding environments. Its fanless design supports operation from -40°C to 75°C, ensuring reliable performance in harsh conditions with resistance to impact, thermal shock, and electrical noise.
With full-duplex switching, PoE watchdog for auto-recovery, 802.1x access control, RADIUS/TACACS+, and intuitive management via eVue™ and eLite™ , the EX78900X balances control and convenience. Lite Layer 3 functions like static routing, RIP, OSPF, and VRRP reduce broadcast traffic and improve network efficiency—making it ideal for smart city, transportation, and industrial automation deployments.
IEC 62443-4-2 Certified – Strengthening cyber resilience for critical industrial and infrastructure applications.
