Description
Product Overview
The EtherWAN EX78934X-0VB-CC is a conformal-coated hardened managed industrial PoE++ switch with twelve 10/100/1000BASE-T(X) powered RJ45 ports and four dual-rate 1G/10G SFP+ fiber uplinks. Its IEEE 802.3bt Type 4 ports support up to 90W individually, within a shared 360W PoE budget. EtherWAN’s installation guide identifies ports 1, 4, 8 and 9 for 90W operation, so verify high-power port assignments on the shipped hardware. Static routing, RIP, OSPF, VRRP, VLANs and industrial redundancy functions support managed networks for surveillance, transportation and automation. Its fanless IP30 aluminum enclosure operates from -40°C to +75°C in a suitable protective cabinet.
The EtherWAN EX78934X-0VB-CC is a conformal-coated EX78900X-series industrial managed Gigabit PoE++ switch offered by Coremicro in Union City, California. EtherWAN’s EX78900X installation guide explicitly lists this -CC model with twelve Gigabit PoE ports and four 1G/10G SFP+ uplinks. Manufacturer series specifications include 360W total PoE output, up to 90W per port, 104Gbps switching fabric, 75.29Mpps forwarding and Lite Layer 3 routing. PoE Type 4 90W operation requires 54–57VDC input, and the guide identifies ports 1, 4, 8 and 9 for simultaneous high-power planning. The enclosure is IP30 rather than weather-sealed; the coating material and its environmental qualifications should be confirmed separately. Coremicro displays Authorized Dealer and Special Order designations. Verify the supplied revision, compatible optics, stock and warranty eligibility before purchasing.
Twelve Gigabit IEEE 802.3bt PoE++ Ports
The EX78934X-0VB-CC offers twelve 10/100/1000BASE-T(X) RJ45 ports supporting compatible PoE devices. EtherWAN lists up to 90W per port under IEEE 802.3bt Type 4, but all powered ports share a 360W chassis budget. The installation guide specifically calls out ports 1, 4, 8 and 9 for 90W operation. Check the actual port markings and combined device demand rather than assuming twelve simultaneous 90W loads.
Four Dual-Rate 1G/10G SFP+ Uplinks
Four 1G/10G SFP+ slots provide high-bandwidth uplinks to matching fiber aggregation and backbone equipment. Compatible optical modules must match the far-end interface, link speed, fiber standard, wavelength and reach. These four uplinks are separate from the twelve powered copper ports.
360W PoE Budget and Redundant DC Input
The 360W maximum PoE allocation is shared across all ports, with 20W maximum switch consumption specified separately without PoE. EtherWAN lists redundant 46–57VDC terminal-block input for basic PoE classes, 52–57VDC for 30W/60W service and 54–57VDC for 90W Type 4 service. Choose a source with adequate continuous output and thermal rating; a nominal 48V supply does not automatically support 90W Type 4.
Lite Layer 3 Routing and Ring Resilience
Managed Lite Layer 3 functions include static routing, RIP v1/v2, OSPF v2 and VRRP, with up to 64 hardware routes. Layer 2 functions include EtherWAN Alpha-Ring, STP/RSTP/MSTP, 802.1Q VLANs and LACP. These features allow properly configured routing, traffic separation and redundant links in industrial networks.
Conformal-Coated Electronics, IP30 Housing
The -CC part number identifies the conformal-coated hardware option, explicitly listed in an EtherWAN installation guide. Specific coating chemistry and qualification have not been independently established. The switch still uses a fanless IP30 aluminum enclosure and requires a suitably protected cabinet wherever dust, rain or moisture exposure exceeds that rating.
Secure Monitoring in Wide-Temperature Sites
EtherWAN specifies -40°C to +75°C operation, with SNMP v1/v2c/v3, Web GUI, CLI, SSH, HTTPS, IEEE 802.1X and RADIUS/TACACS+ among its administration options. Two digital inputs and two relay outputs support industrial alarm integration. Apply secure access policies and use appropriately rated power supplies and optics for the installation environment.

What is the EtherWAN EX78934X-0VB-CC?
The EX78934X-0VB-CC is the conformal-coated variant of a hardened managed EX78900X Gigabit PoE++ switch. It offers twelve powered RJ45 ports, four 1G/10G SFP+ uplinks, Lite Layer 3 routing and a shared 360W PoE budget.
Can all twelve PoE ports deliver 90W at the same time?
No. EtherWAN lists up to 90W for an individual IEEE 802.3bt Type 4 port, but only 360W combined across the switch. The installation guide identifies ports 1, 4, 8 and 9 for 90W use. Verify the power plan and actual hardware revision before connecting high-power loads.
What DC voltage does this switch need for 90W PoE++?
IEEE 802.3bt Type 4 output at 90W requires 54–57VDC. The wider 46–57VDC input range applies to lower PoE classes, and an external supply must also provide sufficient continuous wattage for the switch and connected equipment.
How fast are the EX78934X-0VB-CC SFP+ uplinks?
The switch has four dual-rate 1G/10G SFP+ uplinks. Use compatible SFP+ transceivers, cabling and upstream interfaces for the desired optical link speed and distance.
Does the -CC conformal coating make the switch waterproof?
No. The -CC designation identifies conformal coating, but the published housing protection is IP30. The coating material and environmental qualification have not been separately confirmed, so use a suitably protected cabinet when the location requires it.
Does EX78934X-0VB-CC support Layer 3 routing and network redundancy?
Yes. The EX78900X platform supports static routing, RIP v1/v2, OSPF v2 and VRRP. EtherWAN also lists managed VLANs, STP/RSTP/MSTP and Alpha-Ring for properly configured Layer 2 redundancy.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation and Special Order status for EX78934X-0VB-CC. Contact the store to confirm current availability, the exact coated variant, compatible SFP optics, power supply requirements and manufacturer warranty eligibility.
