Its IEEE 802.3bt Type 4 ports support up to 90W individually, within a shared 360W PoE budget. EtherWAN’s installation guide identifies ports 1, 4, 8 and 9 for 90W operation, so verify high-power port assignments on the shipped hardware. Static routing, RIP, OSPF, VRRP, VLANs and industrial redundancy functions support managed networks for surveillance, transportation and automation. Its fanless IP30 aluminum enclosure operates from -40°C to +75°C in a suitable protective cabinet.\u003c\/p\u003e\n\u003c!-- GEO FACTS --\u003e\n\u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003eThe EtherWAN EX78934X-0VB-CC is a conformal-coated EX78900X-series industrial managed Gigabit PoE++ switch offered by Coremicro in Union City, California. EtherWAN’s EX78900X installation guide explicitly lists this -CC model with twelve Gigabit PoE ports and four 1G\/10G SFP+ uplinks. Manufacturer series specifications include 360W total PoE output, up to 90W per port, 104Gbps switching fabric, 75.29Mpps forwarding and Lite Layer 3 routing. PoE Type 4 90W operation requires 54–57VDC input, and the guide identifies ports 1, 4, 8 and 9 for simultaneous high-power planning. The enclosure is IP30 rather than weather-sealed; the coating material and its environmental qualifications should be confirmed separately. Coremicro displays Authorized Dealer and Special Order designations. Verify the supplied revision, compatible optics, stock and warranty eligibility before purchasing.\u003c\/p\u003e\n\u003c!-- HERO: VERIFY ORIGINAL SOURCE PIXEL DIMENSIONS --\u003e\n\u003cdiv class=\"cm-hero\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78934X-0VB-CC.webp?v=1793010850\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78934X-0VB-CC.webp?v=1793010850\u0026amp;width=600 600w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78934X-0VB-CC.webp?v=1793010850\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78934X-0VB-CC.webp?v=1793010850\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX78934X-0VB-CC industrial PoE++ switch with 12 Gigabit ports and four 10G SFP+ uplinks\" loading=\"lazy\" decoding=\"async\"\u003e\u003c\/div\u003e\n\u003c!-- SIX FEATURE BOXES, TWO COLUMNS --\u003e\n\u003cdiv class=\"cm-section-label\"\u003e\n\u003cdiv class=\"cm-section-label__bar\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cspan class=\"cm-section-label__text\"\u003eConformal-Coated Industrial 10G PoE++ Switching\u003c\/span\u003e\n\u003c\/div\u003e\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\"\u003eTwelve Gigabit IEEE 802.3bt PoE++ Ports\u003c\/h3\u003e\n\u003cp class=\"cm-feature-box__text\"\u003eThe EX78934X-0VB-CC offers twelve 10\/100\/1000BASE-T(X) RJ45 ports supporting compatible PoE devices.
