Description
Product Overview
The EtherWAN EX78912G-0BT is a hardened Layer 3 managed Gigabit Ethernet switch designed for industrial networks requiring high-power PoE++, flexible fiber uplinks and advanced network control. It combines four IEEE 802.3bt PoE++ ports rated up to 90W each, four additional Gigabit RJ45 ports and two tri-speed 100/1000/2500BASE SFP interfaces. A shared 240W PoE budget supports compatible powered devices, while Layer 3 routing, Ethernet ring redundancy and managed traffic controls provide flexibility for industrial network deployments. Its fanless IP30 enclosure, redundant DC power inputs and -40 to 75°C operating range support security infrastructure, transportation systems, industrial automation and other demanding installations.
The EtherWAN EX78912G-0BT is a hardened managed Layer 3 Gigabit Ethernet PoE++ switch in the EX78900G Series, available from Coremicro, an authorized EtherWAN dealer based in Union City, California. The model provides eight 10/100/1000BASE-T(X) copper ports, including four IEEE 802.3af/at/bt PoE++ ports, plus two 100/1000/2500BASE SFP uplinks. Each powered port supports up to 90W with a total PoE budget of 240W. Supported features include static routing, RIP v1/v2, OSPF v2, VRRP v2, VLANs, link aggregation, ERPS redundancy and RESTful API management. The switch uses redundant 46-57VDC terminal-block power inputs, a fanless IP30 metal enclosure and DIN-rail mounting. EtherWAN specifies a limited lifetime manufacturer warranty subject to its warranty policy. Coremicro lists the product as Special Order; current pricing, availability and warranty eligibility should be confirmed before purchase.
Four 90W IEEE 802.3bt PoE++ Ports
Four Gigabit Ethernet ports support IEEE 802.3bt Type 4 PoE++ output up to 90W per port, with backward compatibility for IEEE 802.3at and IEEE 802.3af powered devices. This allows compatible high-power PTZ cameras, wireless access points, IP surveillance equipment and other PoE devices to receive power and network connectivity through Ethernet cabling. The total PoE power budget is limited to 240W across all four powered ports. For 90W operation, EtherWAN specifies a 54-57VDC input range, so power supply selection and the combined device load must be verified before deployment.
Eight Gigabit Ethernet Copper Ports
Eight 10/100/1000BASE-T(X) RJ45 interfaces provide Gigabit connectivity for powered and non-powered network equipment. Four ports include PoE++ output, while the remaining four support standard Ethernet data connections without PoE power delivery. This mixed configuration lets industrial integrators connect high-power devices alongside computers, controllers, networking appliances and compatible security equipment. Auto-negotiation and Auto MDI/MDIX simplify Ethernet connections, while managed switching features provide control over network traffic and connected endpoints.
Dual Tri-Speed 2.5G SFP Fiber Uplinks
Two SFP interfaces support 100Mbps, 1Gbps and 2.5Gbps link speeds using compatible transceiver modules. These tri-speed uplinks provide options for connecting local Gigabit Ethernet equipment to optical fiber networks, distribution switches and higher-bandwidth aggregation infrastructure. The 2.5Gbps capability helps accommodate uplink traffic from multiple Gigabit devices without requiring a dedicated 10GbE interface. Supported transmission distance, optical media and actual link speed depend on the selected SFP modules and connected network equipment.
Layer 3 Routing and ERPS Redundancy
Managed Layer 3 functions include static routing, RIP v1/v2, OSPF v2 and VRRP v2, with support for up to 64 hardware route entries. These capabilities allow network engineers to build routed network segments and configure routing redundancy within industrial infrastructure. For Layer 2 resilience, the switch supports STP, RSTP, MSTP and ITU-T G.8032 Ethernet Ring Protection Switching. VLAN tagging, LACP link aggregation and IGMP snooping provide additional tools for segmenting traffic, organizing network connections and managing multicast delivery.
Secure Network Management and Traffic Control
The EX78900G Series supports web GUI, CLI, Telnet, SNMP v1/v2c/v3 and RESTful API management for remote configuration and network monitoring. Access controls include RADIUS, TACACS+, SSH, HTTPS, MAC filtering, access control lists and multi-user privilege management. Network administrators can also use DHCP services, LLDP, RMON, port mirroring and system logging to diagnose connections and maintain equipment visibility. Eight QoS priority queues per port, DSCP classification, weighted round robin and strict scheduling help manage traffic priorities across connected devices.
Hardened Fanless Industrial Construction
The metal IP30 enclosure is designed for industrial installations requiring stable network operation across a -40 to 75°C operating temperature range. Fanless cooling eliminates mechanical fan maintenance, while DIN-rail mounting supports integration into industrial cabinets and equipment enclosures. Redundant 46-57VDC terminal-block inputs provide industrial power connection options, with voltage requirements determined by the connected PoE load. The compact 62 × 125 × 145 mm chassis and 0.75 kg weight support installations where cabinet space is limited. EtherWAN also lists NEMA TS2 and EN 50121-4 compliance for the series.
