Description
Product Overview
The EtherWAN EX78922E-0VB-CC is a hardened managed Gigabit Ethernet PoE switch designed for industrial networks requiring powered device connectivity, fiber uplinks and Layer 3 management. Part of the EX78900E Series, its documented base configuration combines eight 10/100/1000BASE-T(X) PoE ports with two dual-rate 100/1000BASE SFP interfaces. A shared 240W PoE budget, redundant DC power inputs and network redundancy features support IP surveillance, transportation infrastructure, industrial automation and distributed security installations. The conformal-coated variant is listed by Coremicro for applications where additional electronic component protection is required, while the fanless IP30 enclosure and wide operating temperature range support demanding industrial environments.
The EtherWAN EX78922E-0VB-CC is a hardened managed Layer 3 Gigabit Ethernet PoE switch offered by Coremicro, an authorized EtherWAN dealer based in Union City, California. Coremicro identifies the product as a conformal-coated variant of the EX78922E configuration in EtherWAN's EX78900E Series. The manufacturer documents eight 10/100/1000BASE-T(X) PoE ports, two 100/1000BASE SFP uplinks, a 240W total PoE budget and up to 60W output per supported port. Layer 3 functions include static routing, RIP v1/v2, OSPF v2 and VRRP, with Alpha-Ring redundancy and managed Layer 2 networking. The series specifies redundant 46-57VDC input, DIN-rail mounting, an IP30 aluminum enclosure and -40 to 75°C operation. EtherWAN lists a limited lifetime manufacturer warranty subject to its warranty policy. Confirm coating specifications, current pricing, availability and warranty eligibility for the exact -CC model before purchase.
Eight Gigabit Ethernet PoE Ports
Eight 10/100/1000BASE-T(X) RJ45 ports provide Gigabit data connectivity and Power over Ethernet for compatible network equipment. EtherWAN documents different output levels across the port groups, with up to 30W on ports 1-4 and up to 60W on ports 5-8. Support for IEEE 802.3af, 802.3at and 802.3bt allows integration with compatible IP cameras, wireless access points, security systems and industrial network devices. Auto-negotiation and Auto MDI/MDIX simplify Ethernet installation, while the managed switching platform provides control over connected devices and network traffic.
Dual 100/1000BASE SFP Fiber Uplinks
Two dual-rate SFP interfaces support 100Mbps and 1Gbps network connections using compatible optical transceiver modules. These ports provide options for connecting local Gigabit Ethernet devices to fiber backbone infrastructure, remote network cabinets and aggregation switches. Fiber connections help network designers accommodate longer transmission distances than conventional copper Ethernet links when suitable transceivers are selected. The installation must use compatible SFP modules, optical cabling and matching link specifications at both ends of the connection.
240W PoE Budget with 60W Port Output
The EX78900E Series provides a maximum combined PoE power budget of 240W for the documented eight-port configuration. Four ports support up to 30W output, while the remaining four support up to 60W for compatible IEEE 802.3bt Type 3 equipment. A PoE watchdog function monitors connected powered devices and supports network maintenance. The switch uses redundant 46-57VDC terminal-block power inputs, with 52-57VDC required for supported 30W and 60W powered-device operation. Calculate the total power consumption of connected devices before selecting a supply or deploying high-power equipment.
Lite Layer 3 Routing and Network Management
Lite Layer 3 functionality supports structured industrial network designs that require routing between network segments. EtherWAN documents static routing, RIP v1/v2, OSPF v2 and VRRP, with a hardware routing table supporting up to 64 entries. Network administrators can configure and monitor the switch through CLI, Telnet, web GUI and SNMP v1/v2c/v3. Additional functions include IPv4/IPv6 management, DHCP server/client, NTP synchronization, LLDP, port mirroring and RMON. These tools help engineers manage network connections, troubleshoot devices and maintain visibility across distributed industrial installations.
EtherWAN Alpha-Ring Redundancy and Security
EtherWAN Alpha-Ring provides network fault recovery capabilities for supported industrial Ethernet ring topologies. The EX78900E Series also supports STP, RSTP, MSTP, IEEE 802.1Q VLANs, LACP link aggregation and IGMP snooping v1/v2/v3 for traffic segmentation and network resilience. Security controls include IEEE 802.1X authentication, RADIUS, TACACS+, SSH, SSL/HTTPS, MAC address filtering, access control lists and storm control. These functions help integrators organize network traffic, restrict unauthorized access and maintain connectivity in managed industrial Ethernet deployments.
Conformal-Coated Industrial Switch Design
Coremicro identifies the EX78922E-0VB-CC as a conformal-coated variant intended to provide additional protection for electronic components. The EX78900E Series features a fanless aluminum enclosure with IP30 protection, DIN-rail mounting and an operating temperature range of -40 to 75°C. Its 72 × 140 × 170 mm chassis is designed for industrial cabinets and infrastructure installations where space and environmental tolerance are important. EtherWAN lists NEMA TS2, EN 50121-4 and industrial environmental compliance for the series. The coating material, coverage and any coating-specific environmental ratings should be confirmed for this exact SKU.
