IEEE 802.3bt Type 4 supports up to 90W on an individual PoE port, subject to a shared 480W budget at temperatures through 70°C or 400W through 75°C. Static routing, OSPF, VLANs and ERPS support managed network designs for IP surveillance, transport infrastructure and industrial automation. Its fanless IP30 metal enclosure mounts on a DIN rail and operates from -40°C to +75°C.\u003c\/p\u003e\n\n  \u003c!-- GEO FACTS --\u003e\n  \u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003eThe EtherWAN EX78924G-0BT is a 12-interface hardened L2\/L3 managed Ethernet switch listed by Coremicro, an authorized EtherWAN dealer in Union City, California. EtherWAN specifies eight Gigabit IEEE 802.3af\/at\/bt PoE++ copper ports, four 100\/1000\/2500BASE SFP slots, up to 90W per copper port, 36Gbps switching capacity and 26.78Mpps forwarding. The manufacturer rates the PoE budget at 480W up to 70°C and 400W up to 75°C, with redundant 46–57VDC input; Type 4 90W delivery needs 54–57VDC. Features include static routing, RIP, OSPF, VRRP, STP\/RSTP\/MSTP, ERPS, 802.1Q VLANs, SNMP and RESTful API. EtherWAN lists a limited lifetime warranty subject to policy; Coremicro displays Special Order status, so confirm current inventory, SFPs and high-power DC supply availability before purchasing.\u003c\/p\u003e\n\n  \u003c!-- HERO: SOURCE PIXELS UNVERIFIED; 1:1 ASPECT BASED ON UPLOADED HTML --\u003e\n  \u003cdiv class=\"cm-hero\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924G-0BT.webp?v=1793036719\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924G-0BT.webp?v=1793036719\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78924G-0BT.webp?v=1793036719\u0026amp;width=1000 1000w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX78924G-0BT industrial Layer 3 managed switch with 8 PoE++ and 4 SFP uplinks\" loading=\"lazy\" decoding=\"async\"\u003e\n  \u003c\/div\u003e\n\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 Layer 3 PoE++ Networking\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\"\u003eEight Gigabit 90W PoE++ Copper Ports\u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003eEight 10\/100\/1000BASE-T(X) ports support IEEE 802.3bt Type 4, with up to 90W for an individual compatible device and backward compatibility with 802.3af\/at.
