Description
Product Overview
The EtherWAN EX78924H-0VB is a hardened Layer 2/Lite Layer 3 managed industrial Ethernet switch combining eight 10/100/1000BASE-T PoE copper ports with four dual-rate 100/1000BASE SFP fiber uplinks. EtherWAN’s installation guide identifies four 30W ports and four designated ports supporting up to 90W IEEE 802.3bt Type 4, with a shared 360W PoE power budget. Static routing, RIP, OSPF, VRRP, VLANs and Alpha-Ring support controlled industrial networks. Its fanless IP30 aluminum enclosure, DIN-rail mounting and -40°C to +75°C operating range suit protected industrial network cabinets. Confirm the port assignments and power-supply rating before connecting high-power devices.
The EtherWAN EX78924H-0VB is a 12-interface hardened managed Gigabit PoE++ industrial switch listed by Coremicro in Union City, California. The model provides eight Gigabit RJ45 PoE ports (four 30W and four up to 90W according to EtherWAN’s installation guide), four 100/1000BASE SFP uplinks, a 360W combined PoE budget, 32Gbps switching fabric and 23.5Mpps forwarding. The manufacturer specifies redundant 46–57VDC terminal-block input, with 54–57VDC required for IEEE 802.3bt Type 4 90W output, plus two digital inputs, two alarm relays, IP30 housing and -40°C to +75°C operation. Coremicro displays Authorized Dealer and Special Order designations; verify stock, exact high-power port labeling, SFP compatibility and warranty eligibility before purchase.
Four 30W and Four 90W PoE Ports
The eight copper Gigabit ports support compatible PoE endpoints. EtherWAN’s EX78900H installation guide identifies four 30W ports and four designated 90W IEEE 802.3bt Type 4 ports for EX78924H-0VB. The 360W budget is shared, so all eight ports cannot simultaneously operate at their individual maximum ratings. Match device loads to the switch’s labeled port assignments.
Four Dual-Rate Gigabit SFP Uplinks
Four independent 100/1000BASE SFP ports connect to compatible fiber transceivers and upstream equipment. They support 100Mbps and 1Gbps links, not 2.5Gbps uplinks. Verify optical module type, fiber mode, wavelength, link distance and speed before installation.
Lite Layer 3 Routing and VRRP
The EX78900H platform provides static IPv4 routes, RIP v1/v2, OSPF v2 and VRRP routing redundancy, with a manufacturer-listed limit of 64 hardware routes. Use these features to interconnect suitable IP network segments with a documented routing configuration.
Managed VLANs and Network Redundancy
IEEE 802.1Q VLANs, STP/RSTP/MSTP, EtherWAN Alpha-Ring, LACP, IGMP snooping and QoS help organize and protect network traffic. EtherWAN lists up to 256 VLANs, 16K MAC addresses and 9KB jumbo frames. Network resilience still depends on the complete topology and configuration.
Secure Management and Industrial I/O
Web GUI, CLI, SNMP, SSH, HTTPS, RADIUS/TACACS+ and access control lists provide configuration and administration choices. Two digital inputs and two relay outputs allow supported alarm integration; relay contacts are rated 0.5A at 48VDC. Configure secure access before connecting to production networks.
Fanless IP30 Design and Redundant Power
The aluminum enclosure operates from -40°C to +75°C and mounts on a DIN rail in a protected equipment cabinet. Redundant terminal-block power accepts 46–57VDC for lower-power classes, but 90W Type 4 operation requires 54–57VDC. Select appropriately rated supplies for the switch’s 20W maximum consumption without PoE plus connected loads.
Industrial IP Surveillance
Power compatible cameras and network endpoints, observing the 30W and designated 90W PoE port limits.
Transportation Networks
Connect managed roadside or transit network devices in protected cabinets with suitable industrial approvals.

What is the EtherWAN EX78924H-0VB used for?
The EX78924H-0VB is a hardened managed industrial Gigabit Ethernet PoE++ switch with eight powered RJ45 ports and four dual-rate 100/1000BASE SFP fiber uplinks. It supports Lite Layer 3 routing for surveillance, transportation and automation networks.
Are all eight EX78924H-0VB PoE ports rated for 90W?
No. EtherWAN’s EX78900H installation guide specifies four 30W PoE ports and four designated ports capable of up to 90W for this exact model. Check the physical port labeling and manufacturer instructions before connecting high-power devices.
Can the EX78924H-0VB supply 360W plus four additional 30W loads?
No. The 360W PoE budget is the shared total. The per-port maximum ratings cannot all be used simultaneously when their combined power demand exceeds 360W. Leave headroom for the switch and power-supply requirements.
Which DC input voltage is required for 90W IEEE 802.3bt PoE?
EtherWAN lists 54–57VDC for IEEE 802.3bt Type 4 90W operation. The general redundant input range is 46–57VDC, but lower voltages do not support every high-power PoE mode.
How many SFP uplinks and what link speeds does this switch have?
The EX78924H-0VB has four dual-rate 100/1000BASE SFP slots supporting compatible 100Mbps and 1Gbps modules. It is not a 2.5G or 10G SFP uplink switch.
Does the EX78924H-0VB support Layer 3 routing and ring redundancy?
Yes. The EX78900H series supports static routing, RIP v1/v2, OSPF v2 and VRRP, along with STP/RSTP/MSTP and EtherWAN Alpha-Ring. Confirm firmware and complete topology requirements before enabling these functions.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation for the EX78924H-0VB and labels it Special Order. Contact Coremicro to confirm current availability, suitable 54–57VDC power supplies, compatible optical modules and manufacturer warranty eligibility.
