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 four dual-rate 1/10G SFP+ uplinks for high-bandwidth fiber connectivity. The fanless design supports operation from -40 to 75C, ensuring stable performance in harsh environments 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. EtherWAN - "When Connectivity is Crucial."
