It combines eight 10/100/1000BASE-T(X) PoE copper ports with two dual-rate 100/1000BASE SFP interfaces. The switch supports IEEE 802.3bt power delivery up to 90W on designated ports and a maximum shared PoE budget of 360W. Managed network security, VLANs and redundancy functions support IP surveillance, transportation infrastructure, industrial automation and distributed Ethernet installations. Its fanless IP30 aluminum enclosure and DIN-rail mounting support operation in demanding industrial environments. Explore more professional networking equipment at Coremicro.
The EtherWAN EX78922H-0VB is a hardened managed Lite Layer 3 Gigabit Ethernet PoE++ switch in the EX78900H Series, listed by Coremicro in Union City, California. 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.
Eight Gigabit Ethernet PoE Ports
Eight 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.
360W PoE Budget with 90W Output
The 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.
Dual Gigabit SFP Fiber Uplinks
Two 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.
Lite Layer 3 Routing and Network Redundancy
Lite Layer 3 functionality provides routing options for industrial networks requiring communication between managed network segments. EtherWAN specifies static routing, RIP v1/v2, OSPF v2 and VRRP, with a hardware routing table supporting up to 64 entries. Layer 2 functions include IEEE 802.1Q VLAN tagging, LACP link aggregation, IGMP snooping and STP/RSTP/MSTP. EtherWAN Alpha-Ring adds network fault recovery capabilities for supported ring topologies. These features help network engineers design segmented networks, control multicast traffic and maintain resilient Ethernet connections.
Managed Network Security and Administration
The EX78900H Series provides management through a web GUI, CLI, Telnet, SSH and SNMP v1/v2c/v3. Security functions include IEEE 802.1X authentication, RADIUS, TACACS+, HTTPS, MAC filtering, access control lists and storm control. Administrators can use DHCP server/client functions, LLDP, NTP, RMON, port mirroring and Modbus TCP to configure and monitor industrial networks. Eight QoS priority queues per port support traffic classification through IEEE 802.1p, DSCP, weighted round robin and strict scheduling. EtherWAN eVue and eLite utilities provide additional configuration, discovery and monitoring options.
Hardened Fanless DIN-Rail Design
The hardened aluminum enclosure features IP30 protection, fanless cooling and DIN-rail mounting for industrial control cabinets and infrastructure equipment rooms. EtherWAN specifies an operating temperature range of -40 to 75°C, with industrial shock, vibration and electromagnetic compatibility testing. Redundant DC power inputs, two digital inputs and two relay outputs provide connection options for industrial power and monitoring systems. The enclosure measures 72 × 140 × 170 mm and weighs 1.5 kg. The series lists NEMA TS2, EN 50121-4 and UL 61010 standards. Outdoor applications require an appropriately rated protective enclosure.
