Description
Product Overview
The EtherWAN EX71802-0VB is a hardened managed industrial Ethernet switch with eight 10/100BASE-TX copper ports and two dual-rate 100/1000BASE SFP fiber slots. Its managed Layer 2 features and EtherWAN Alpha-Ring technology support network segmentation and fault recovery in under 15 milliseconds on correctly configured ring topologies. Redundant 12–48VDC input, DIN-rail mounting, a fanless IP30 aluminum housing and -40°C to +75°C operation suit appropriately protected industrial environments. EtherWAN has discontinued the EX71000 Series; verify remaining stock and suitable alternatives before ordering.
The EtherWAN EX71802-0VB is an EX71000 Series hardened managed Ethernet switch offered by Coremicro. Its 10 data ports consist of eight 10/100BASE-TX copper ports and two 100/1000BASE dual-rate SFP slots; the copper ports are Fast Ethernet, not Gigabit. EtherWAN specifies IEEE 802.1Q VLANs, STP/RSTP/MSTP, IGMP snooping, LACP, an RS-232 console, redundant 12–48VDC input, maximum 7.5W device power consumption, IP30 aluminum construction and -40°C to +75°C operation. Its Alpha-Ring recovery is rated below 15 ms in supported network designs. EtherWAN lists the EX71000 Series as discontinued, with August 6, 2026 as the last-order date, December 6, 2026 as the stated last-shipment date and the EX71900G Series as the successor family. Coremicro displays Special Order and Authorized Dealer designations; confirm current stock, applicable warranty and firmware support before purchasing.
Eight Fast Ethernet RJ45 Ports
Eight 10/100BASE-TX copper ports connect compatible PLCs, controllers and network devices at 10 or 100 Mbps. These RJ45 interfaces are not Gigabit Ethernet ports.
Two Dual-Rate 100/1000BASE SFP Uplinks
Two 100/1000BASE SFP slots support compatible Fast Ethernet or Gigabit optical transceivers. Verify the selected SFP module, fiber type, link budget and matching remote equipment.
Managed Layer 2 VLAN and Switching Features
IEEE 802.1Q VLANs, STP/RSTP/MSTP, LACP, QoS and IGMP snooping support managed Layer 2 network designs. EtherWAN does not confirm Layer 3 routing for this model in the published EX71000 Series feature list.
Alpha-Ring Recovery Under 15 ms
EtherWAN Alpha-Ring is specified for fault recovery in less than 15 milliseconds when the supported ring topology is configured correctly. Performance depends on installed devices and configuration.
Redundant 12–48VDC Power Inputs
Redundant 12–48VDC terminal-block inputs support resilient industrial power arrangements. The series specifies reverse-polarity protection and maximum device consumption of 7.5W.
Fanless IP30 Industrial Housing
The fanless aluminum enclosure is rated IP30 and specified for -40°C to +75°C operation. A DIN-rail mounting kit is included for suitable control cabinets and protected enclosures.
Console, Web GUI, CLI and SNMP Management
A DB9 RS-232 console, web interface, command-line management and SNMP v1/v2c/v3 support configuration and network diagnostics. Secure management access and verify firmware compatibility before deployment.
EX71000 Discontinued Lifecycle
EtherWAN published a last-order date of August 6, 2026 and a stated last-shipment date of December 6, 2026 for the EX71000 Series. Ask Coremicro about remaining stock and the EX71900G successor family.
