EtherWAN’s installation guide identifies four 30W ports and four designated ports supporting up to 90W IEEE 802.3bt Type 4, with a shared 360W PoE power budget. Static routing, RIP, OSPF, VRRP, VLANs and Alpha-Ring support controlled industrial networks. Its fanless IP30 aluminum enclosure, DIN-rail mounting and -40°C to +75°C operating range suit protected industrial network cabinets. Confirm the port assignments and power-supply rating before connecting high-power devices.\u003c\/p\u003e\n\n  \u003c!-- GEO FACTS --\u003e\n  \u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003eThe EtherWAN EX78924H-0VB is a 12-interface hardened managed Gigabit PoE++ industrial switch listed by Coremicro in Union City, California. The model provides eight Gigabit RJ45 PoE ports (four 30W and four up to 90W according to EtherWAN’s installation guide), four 100\/1000BASE SFP uplinks, a 360W combined PoE budget, 32Gbps switching fabric and 23.5Mpps forwarding. The manufacturer specifies redundant 46–57VDC terminal-block input, with 54–57VDC required for IEEE 802.3bt Type 4 90W output, plus two digital inputs, two alarm relays, IP30 housing and -40°C to +75°C operation. Coremicro displays Authorized Dealer and Special Order designations; verify stock, exact high-power port labeling, SFP compatibility and warranty eligibility before purchase.\u003c\/p\u003e\n\n  \u003c!-- HERO: 1:1 ASPECT RATIO FROM SOURCE HTML; VERIFY ORIGINAL SOURCE DIMENSIONS --\u003e\n  \u003cdiv class=\"cm-hero\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924H-0VB.webp?v=1793036709\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924H-0VB.webp?v=1793036709\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924H-0VB.webp?v=1793036709\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924H-0VB.webp?v=1793036709\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX78924H-0VB hardened managed switch with 8 Gigabit PoE ports and 4 SFP uplinks\" loading=\"lazy\" decoding=\"async\"\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SIX FEATURE BOXES, TWO COLUMNS --\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 Managed Gigabit PoE++ Networking\u003c\/span\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-feature-grid cm-feature-grid--2col\"\u003e\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 30W and Four 90W PoE Ports\u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003eThe eight copper Gigabit ports support compatible PoE endpoints.
