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.\u003c\/p\u003e\n\n\u003c!-- GEO FACTS --\u003e\n\u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003eThe 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.\u003c\/p\u003e\n\n\u003c!-- HERO IMAGE --\u003e\n\u003cdiv class=\"cm-hero\"\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78912G-0BT.webp?v=1793036755\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78912G-0BT.webp?v=1793036755\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78912G-0BT.webp?v=1793036755\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78912G-0BT.webp?v=1793036755\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX78912G-0BT industrial managed switch with 90W PoE++ and dual 2.5G SFP uplinks\" loading=\"lazy\" decoding=\"async\"\u003e\n\u003c\/div\u003e\n\n\u003c!-- KEY FEATURES --\u003e\n\u003cdiv class=\"cm-section-label\"\u003e\n  \u003cdiv class=\"cm-section-label__bar\"\u003e\u003c\/div\u003e\n  \u003cspan class=\"cm-section-label__text\"\u003eIndustrial PoE++ Network Connectivity\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"cm-feature-grid cm-feature-grid--2col\"\u003e\n\n  \u003cdiv class=\"cm-feature-box\"\u003e\n    \u003cdiv class=\"cm-feature-box__icon\"\u003e⚡\u003c\/div\u003e\n    \u003ch3 class=\"cm-feature-box__title\"\u003eFour 90W IEEE 802.3bt PoE++ Ports\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eFour 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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-feature-box\"\u003e\n    \u003cdiv class=\"cm-feature-box__icon\"\u003e🔌\u003c\/div\u003e\n    \u003ch3 class=\"cm-feature-box__title\"\u003eEight Gigabit Ethernet Copper Ports\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eEight 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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-feature-box\"\u003e\n    \u003cdiv class=\"cm-feature-box__icon\"\u003e🌐\u003c\/div\u003e\n    \u003ch3 class=\"cm-feature-box__title\"\u003eDual Tri-Speed 2.5G SFP Fiber Uplinks\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eTwo SFP interfaces support 100Mbps, 1Gbps and 2.5Gbps link speeds using compatible transceiver modules.

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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-feature-box\"\u003e\n    \u003cdiv class=\"cm-feature-box__icon\"\u003e🛡️\u003c\/div\u003e\n    \u003ch3 class=\"cm-feature-box__title\"\u003eSecure Network Management and Traffic Control\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eThe 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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-feature-box\"\u003e\n    \u003cdiv class=\"cm-feature-box__icon\"\u003e🌡️\u003c\/div\u003e\n    \u003ch3 class=\"cm-feature-box__title\"\u003eHardened Fanless Industrial Construction\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eThe 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.
