The model provides eight 10\/100\/1000BASE-T(X) PoE ports, two 100\/1000BASE SFP uplinks and a total PoE power budget of 360W. EtherWAN's EX78900H Quick Installation Guide identifies four 30W ports and four 90W ports, while the Coremicro listing describes four 60W and four 90W ports; the exact allocation should be confirmed before deployment. Supported networking features include static routing, RIP v1\/v2, OSPF v2, VRRP, VLANs and EtherWAN Alpha-Ring. The switch supports redundant DC power inputs, DIN-rail mounting, fanless operation and a -40 to 75°C operating range. EtherWAN lists a limited lifetime manufacturer warranty subject to its warranty policy. Coremicro currently lists the model as Special Order, so 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-EX78922H-0VB.webp?v=1793036731\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78922H-0VB.webp?v=1793036731\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78922H-0VB.webp?v=1793036731\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX78922H-0VB.webp?v=1793036731\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX78922H-0VB industrial Gigabit PoE++ managed switch with eight RJ45 ports and dual 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 Gigabit PoE++ 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\"\u003eEight Gigabit Ethernet PoE Ports\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eEight 10\/100\/1000BASE-T(X) RJ45 ports provide Gigabit Ethernet connectivity and Power over Ethernet for compatible industrial network devices. The model combines standard-power PoE interfaces with designated high-power IEEE 802.3bt ports, allowing equipment with different power requirements to share one managed switching platform. Typical connected devices include IP cameras, compatible wireless access points, security equipment and industrial Ethernet endpoints. Auto-negotiation and Auto MDI\/MDIX support straightforward copper Ethernet connections. Verify the individual port ratings against the physical unit before assigning high-power 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\"\u003e360W PoE Budget with 90W Output\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eThe EX78922H-0VB supports a maximum combined PoE budget of 360W, with IEEE 802.3bt Type 4 power delivery up to 90W on supported ports. EtherWAN's installation guide specifies four 30W ports and four 90W ports, although Coremicro's current listing describes four 60W and four 90W ports. Both configurations share the same published total budget. Engineers should calculate the combined demand of all connected devices and confirm port allocation before installation. EtherWAN specifies 54-57VDC input for 90W PoE operation, making suitable DC power supply selection essential.\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 Gigabit SFP Fiber Uplinks\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eTwo dual-rate SFP interfaces support 100Mbps and 1Gbps network connections using compatible optical transceivers. These uplinks connect Gigabit copper network endpoints to fiber backbone infrastructure, aggregation switches or remote network cabinets. Fiber connectivity is useful in distributed security installations, transportation networks and industrial facilities where equipment is separated by longer distances. Transceiver selection must match the required link speed, fiber type, optical wavelength, connector and transmission distance. The EX78922H-0VB uses 100\/1000BASE SFP interfaces rather than 2.5G or 10G SFP+ uplinks.\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\"\u003eLite Layer 3 Routing and Network Redundancy\u003c\/h3\u003e\n    \u003cp class=\"cm-feature-box__text\"\u003eLite Layer 3 functionality provides routing options for industrial networks requiring communication between managed network segments.
