Description
Product Overview
The EtherWAN EX41922-T is a hardened unmanaged four-port industrial Ethernet switch that combines two 10/100/1000BASE-T PoE+ copper ports with two dual-rate 100/1000BASE SFP fiber uplinks. It supplies up to 30W to each compatible PoE+ device within a 60W total budget and uses DIP switches to select 100BASE operation for its SFP ports. Redundant 52–57VDC power, a configurable link/power fault relay, a fanless IP30 metal enclosure and a -40°C to +75°C operating range suit protected industrial cabinets. EtherWAN has discontinued this model; confirm remaining inventory and the requirements of any replacement before ordering.
The EtherWAN EX41922-T is a hardened unmanaged Gigabit PoE+ industrial Ethernet switch listed by Coremicro in Union City, California. The unit has two 10/100/1000BASE-T IEEE 802.3af/at PoE ports, two 100/1000BASE SFP slots, a 30W per-port PoE+ limit and a 60W shared PoE budget. EtherWAN specifies redundant 52–57VDC terminal-block input, a 0.5A at 48VDC fault relay, 10K-byte jumbo frames, an 8K MAC table, a metal IP30 enclosure, DIN-rail mounting and -40°C to +75°C operation. Its end-of-life notice dated August 11, 2025 lists December 31, 2025 as the final ordering date, June 30, 2026 as the final shipment date and TG103H-0442 as the successor. Coremicro currently labels its EX41922-T listing Special Order and Authorized Dealer. Check remaining stock, DC power supply, SFP compatibility and manufacturer warranty eligibility before purchase.

Product Lifecycle

Two Gigabit PoE+ Copper Ports
Two 10/100/1000BASE-T RJ45 ports supply Ethernet connectivity and IEEE 802.3af/at PoE+ power to compatible endpoints. Each supports up to 30W, subject to the shared 60W switch budget.
Two DIP-Selectable 100/1000BASE SFP Uplinks
Two independent SFP slots accept compatible 100BASE or 1000BASE modules. Switch DIP controls select 100BASE operation; match transceiver speed, fiber type, wavelength and the far-end interface.
Hardened -40°C to +75°C Operation
A specified -40°C to +75°C operating range supports temperature-variable equipment areas. The enclosure, SFP optics, connected PoE devices and power supplies must each meet site conditions.
Redundant 52–57VDC Input for PoE
Dual terminal-block inputs support industrial power redundancy. Use a correctly rated 52–57VDC power supply arrangement and confirm available capacity when both powered copper ports approach the full 60W PoE budget.
Power and Link Failure Alarm Relay
One normally open/normally closed relay, rated 0.5A at 48VDC, reports supported fault conditions. DIP switches can enable port link-failure alarms; verify the contact circuit and alarm settings before wiring.
Fanless IP30 DIN-Rail Enclosure
The metal IP30 housing measures 42 × 90 × 100 mm and weighs 0.37 kg. A DIN-rail mounting kit is listed as included; mount in an appropriately protected cabinet.
Fiber Daisy-Chaining and Alpha-Chain Compatibility
The two SFP ports can form a daisy-chain network path. EtherWAN also lists compatibility with its Alpha-Chain redundancy protocol when used with appropriate managed EtherWAN equipment; this switch itself remains unmanaged.
Store-and-Forward, QoS and Jumbo Frames
EtherWAN specifies store-and-forward switching, QoS, IEEE 802.3az Energy Efficient Ethernet, an 8K MAC table, a 1MB packet buffer and up to 10K-byte jumbo frames.
Industrial PoE Edge and Fiber Backbone
PoE+ copper and selectable-rate SFP uplinks support IP surveillance, industrial control cabinets and remote network endpoints. Verify the entire optical path and each powered device before deployment.
Unmanaged Copper PoE+ with Dual Fiber Uplinks
The EX41922-T is suited to compact industrial edge networks where two compatible PoE-powered devices need copper Gigabit Ethernet and a fiber path back to aggregation equipment. Each SFP port can be configured for 100BASE or 1000BASE operation using hardware DIP switches.
This model has no web-managed VLAN or routing interface. Alpha-Chain redundancy is specified only when interconnected with compatible EtherWAN managed switches, so confirm the complete topology before treating it as a redundant network.
Two-PoE Camera Cabinet
Connect up to two compatible IP cameras or other PoE+ devices, keeping the combined power load within 60W. Use a matching SFP uplink to reach the upstream monitoring network.
100/1000BASE Fiber Edge Link
Connect industrial copper endpoints to compatible optical modules. Set the SFP speed using the switch DIP control and check fiber connector, distance, wavelength and far-end compatibility.
Relay-Monitored Equipment Cabinet
Use redundant 52–57VDC power and the fault relay for a protected remote equipment cabinet. Check contact ratings, DIP alarm selections and installation conditions before commissioning.

How many Ethernet ports does the EtherWAN EX41922-T have?
The EtherWAN EX41922-T has four separate physical Ethernet interfaces: two 10/100/1000BASE-T PoE+ RJ45 ports and two 100/1000BASE SFP uplink slots. The model is unmanaged, without a web-based switch configuration interface.
What is the EX41922-T PoE power budget?
The EX41922-T supports up to 30W on each of its two IEEE 802.3af/at PoE+ copper ports, with a shared 60W budget. The connected devices and DC supply must meet the total power requirement.
Which SFP speeds can the EX41922-T use?
The EX41922-T provides two dual-rate SFP ports with 100BASE or 1000BASE operation selected through DIP switches. Compatible SFP modules and matched far-end fiber interfaces are required.
Does the EX41922-T support power redundancy and fault alarms?
The EX41922-T has two redundant 52–57VDC inputs and one normally open/normally closed relay rated 0.5A at 48VDC. Hardware DIP switches enable or disable supported port link-failure alarms.
Can the EX41922-T use EtherWAN Alpha-Chain redundancy?
The EX41922-T can participate in EtherWAN Alpha-Chain deployments when connected to compatible EtherWAN managed switching equipment. The EX41922-T itself remains an unmanaged device; the entire topology and settings must be verified.
Is the EX41922-T discontinued, and which model replaces it?
EtherWAN lists the EX41922-T as discontinued, with December 31, 2025 as the last order date and June 30, 2026 as the final shipment date. EtherWAN names TG103H-0442 as its successor, but that model has eight copper ports with four PoE ports and two SFP slots, so the specifications differ.
Is Coremicro an authorized EtherWAN dealer?
Coremicro displays an Authorized Dealer designation for EtherWAN EX41922-T and lists the product as Special Order. Buyers should confirm actual remaining inventory, power-supply accessories and manufacturer warranty coverage for discontinued units.
Check EX41922-T Stock and Replacement Requirements
Coremicro displays an authorized EtherWAN dealer designation for this model. Because the EX41922-T has been discontinued, contact the team to verify remaining Special Order stock, 52–57VDC power requirements, SFP optical compatibility, manufacturer warranty eligibility and whether TG103H-0442 is suitable for your deployment.
