Product Overview
The EtherWAN EX78934E-0VB-CC is a conformal-coated, hardened managed Gigabit PoE switch for industrial surveillance, transportation and automation networks. Its EX78900E platform combines twelve 10/100/1000BASE-T(X) PoE RJ45 ports with four dual-rate 100/1000BASE SFP uplinks. EtherWAN specifies up to 30W on ports 1–4 and 9–12, up to 60W on ports 5–8, and a shared 240W PoE budget. Lite Layer 3 routing, redundant DC input and a fanless IP30 DIN-rail enclosure support protected industrial cabinet installations. Confirm the exact -CC coating and power-supply requirements before deployment.
The EtherWAN EX78934E-0VB-CC is a conformal-coated industrial managed PoE switch listed by Coremicro in Union City, California. EtherWAN documents the base EX78934E-0VB configuration with twelve Gigabit RJ45 PoE ports, four 100/1000BASE SFP uplinks, IEEE 802.3af/at/bt support, 240W shared PoE output, 32Gbps switching fabric, 23.5Mpps forwarding and Lite Layer 3 functions. Its published power allocation is eight ports at up to 30W and four ports at up to 60W, not 60W on all twelve. An independent procurement schedule identifies the exact -CC suffix as a conformal-coating option, while detailed coating material and environmental qualification have not been separately confirmed. Coremicro displays Authorized Dealer and Special Order labels. Confirm the variant, power supply, stock and warranty before ordering.
Twelve Gigabit PoE Ports with Defined Power Limits
The switch provides twelve 10/100/1000BASE-T(X) powered RJ45 ports. EtherWAN rates ports 1–4 and 9–12 at up to 30W each and ports 5–8 at up to 60W each under IEEE 802.3bt Type 3. The 240W total budget is shared across all ports, so the individual maxima cannot all be drawn simultaneously. Check both the physical port labels and total connected load.
Four Dual-Rate 100M/1G SFP Uplinks
Four 100/1000BASE SFP slots connect the copper PoE edge to compatible optical network infrastructure. They support 100Mbps and 1Gbps transceivers, not 2.5G or 10G uplinks. Choose optics according to the switch interface, fiber type, wavelength, required distance and upstream equipment.
Conformal-Coated Hardware Variant
The -CC suffix identifies the conformal-coated configuration in an independent procurement listing for the exact model. The coating distinguishes this SKU from the standard EX78934E-0VB, but it does not convert the published IP30 enclosure into an outdoor-rated sealed enclosure. Confirm the coating qualification and intended installation environment with EtherWAN.
Lite Layer 3 Routing and Resilient Switching
The EX78900E platform lists static routing, RIP v1/v2, OSPF v2 and VRRP. Managed Layer 2 features include IEEE 802.1Q VLANs, LACP, STP/RSTP/MSTP and EtherWAN Alpha-Ring. These functions support controlled traffic separation and redundant network paths when properly configured.
Monitoring, Access Control and Industrial I/O
Administration options include Web GUI, CLI, SNMP v1/v2c/v3, SSH and HTTPS. IEEE 802.1X, RADIUS/TACACS+ and ACLs provide policy controls, while two digital inputs and two relay outputs support alarm integration. Apply appropriate access restrictions and confirm the installed firmware feature set.
Fanless DIN-Rail Housing and Redundant DC Power
EtherWAN specifies an IP30 aluminum housing, DIN-rail installation and an operating range of -40°C to +75°C for the EX78900E family. The series lists redundant 46–57VDC terminal-block input for lower-power operation; up to 30W or 60W PoE requires 52–57VDC. The power supply must cover the 240W PoE load plus switch consumption.

What is the EtherWAN EX78934E-0VB-CC used for?
The EX78934E-0VB-CC is a conformal-coated managed industrial Gigabit PoE switch with twelve powered RJ45 ports and four 100/1000BASE SFP uplinks. It is intended for compatible surveillance, transportation and automation networks in protected installations.
Are all twelve PoE ports capable of 60W?
No. EtherWAN documents up to 30W on ports 1–4 and 9–12, and up to 60W on ports 5–8 for the EX78934E base configuration. All twelve share a total 240W budget.
What is the total PoE budget for EX78934E-0VB-CC?
The EX78900E platform is rated for 240W combined PoE output. That limit applies across the twelve powered ports; the individual 30W and 60W port ratings cannot all be reached at once.
What does the -CC designation mean?
The -CC version is identified as the conformal-coated configuration of EX78934E-0VB in a separate procurement listing. Specific coating material and environmental qualifications should be verified with EtherWAN. The published chassis protection remains IP30.
Does this switch have four 10G or 2.5G SFP uplinks?
No. EtherWAN’s model ordering specifications identify four dual-rate 100/1000BASE SFP uplinks, supporting 100Mbps or 1Gbps with compatible modules, not 2.5G or 10G links.
What DC input is needed for 60W PoE output?
The published EX78900E series electrical specifications require 52–57VDC for IEEE 802.3bt Type 3 60W PoE operation. Choose an appropriately rated external source that covers the switch consumption and all connected PoE devices.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation and Special Order status for the EX78934E-0VB-CC. Contact Coremicro to verify inventory, the exact conformal-coated configuration, purchasing terms, optical modules and applicable warranty.
