Alpha-Ring Recovery

The EtherWAN EX71620-V0B is a hardened managed industrial Ethernet switch combining six 10/100BASE-TX copper ports and two 100BASE SFP fiber ports. EtherWAN Alpha-Ring technology supports network fault recovery in under 15 milliseconds when the ring is configured correctly. Redundant 12–48VDC input, a fanless IP30 aluminum housing and a -40°C to +75°C operating range support suitable industrial installations. EtherWAN discontinued the EX71000 Series on August 6, 2026, so confirm remaining stock and compatible replacements before ordering.

The EtherWAN EX71620-V0B is an eight-port hardened managed Fast Ethernet switch listed by Coremicro, a retailer based in Union City, California. It has six 10/100BASE-TX RJ45 ports, two 100BASE SFP slots, a DB9 RS-232 console interface, redundant 12–48VDC power input, a maximum stated consumption of 7.5W, an IP30 aluminum enclosure and a -40°C to +75°C operating range. EtherWAN specifies Alpha-Ring recovery under 15 ms in supported configurations and lists a Limited Lifetime Warranty for the EX71000 Series, subject to applicable warranty terms. EtherWAN states that the series was discontinued on August 6, 2026; Coremicro currently lists this model as Special Order and displays an Authorized Dealer designation. Confirm remaining inventory, current price, warranty eligibility, supported firmware and SFP compatibility with Coremicro.

Key Features

01

Six Fast Ethernet Copper Ports

Six 10/100BASE-TX RJ45 interfaces connect compatible PLCs, controllers, traffic devices and other industrial Fast Ethernet equipment. These are 10/100 Mbps interfaces, not Gigabit copper ports.

02

Two 100BASE SFP Fiber Ports

The EX71620-V0B has two 100BASE SFP interfaces for compatible 100 Mbps fiber transceivers. Choose optics that match the fiber type, connector and link budget; the EX71620-V0B does not provide Gigabit SFP uplinks.

03

Alpha-Ring Recovery Under 15 ms

EtherWAN Alpha-Ring supports fault recovery in less than 15 milliseconds in a supported and correctly configured ring topology. Real-world recovery depends on network topology and the installed configuration.

04

Managed Layer 2 Network Features

The EX71000 Series supports IEEE 802.1Q VLANs, STP/RSTP/MSTP, QoS, port mirroring, link aggregation and IGMP snooping. Configure relevant features through supported management tools and firmware.

05

Redundant 12–48VDC Power

Dual 12–48VDC input support through a terminal block helps build resilient industrial power arrangements. EtherWAN also lists reverse-polarity protection and a maximum switch consumption of 7.5W.

06

Hardened Fanless Industrial Design

An IP30 aluminum housing, DIN-rail mounting and a -40°C to +75°C operating range support suitable control cabinets and industrial equipment spaces. The wider system must also meet the required environmental limits.

07

Network Management and Security

The manufacturer lists CLI, web interface, SNMP v1/v2c/v3 and RS-232 console access, together with features such as IEEE 802.1X authentication. Verify the installed firmware and configuration before enabling network management services.

08

Discontinued Series Lifecycle

EtherWAN lists the EX71000 Series as discontinued effective August 6, 2026. Coremicro still shows a Special Order listing; contact the seller to establish remaining stock, applicable support and suitable alternatives.

Real-World Workflows

Industrial Automation

Managed Control Cabinet Networking

Connect compatible PLCs and Fast Ethernet control hardware while using managed network features for segmentation and supported 100BASE SFP links between cabinets.

Transportation Infrastructure

Rail and Traffic Ethernet Links

Use the hardened platform in installations requiring the relevant railway or traffic-control specifications. Confirm EN 50121-4, NEMA TS2 and complete system compliance for the actual project.

Network Maintenance

Existing EX71000 Series Support

Maintain existing EX71620-V0B installations, check configured Alpha-Ring topology and select compatible 100BASE SFP optics. Verify remaining stock or replacement options because the series is discontinued.

Who It's For

Industrial Network Engineers

For designing managed Fast Ethernet networks with 100 Mbps fiber links and ring resilience.

Automation Integrators

For integrating a DIN-rail managed switch into suitable industrial control cabinets.

Transportation Teams

For evaluating compatible network equipment against railway and roadside infrastructure requirements.

Maintenance and Procurement Teams

For maintaining legacy EX71000 Series systems and checking end-of-life replacement availability.

EtherWAN Warranty and Lifecycle

EtherWAN lists a Limited Lifetime Warranty and technical support for the EX71000 Series. The series was discontinued on August 6, 2026, so warranty applicability, access to firmware and technical support, remaining inventory and product replacement options must be confirmed for the specific unit and purchase channel.
