Getting Started | Ethernet Switching Basics
A clear topology diagram speeds up deployment, handoff, and root-cause analysis when links drop or performance degrades.
- Must-have labels: device models, interface types (RJ45/SFP/fiber), plus key parameters (IP/VLAN/ring redundancy, etc.).
- Helpful tool: download a modern Visio topology toolkit with product stencils and quick-draw components for clean, accurate diagrams.
- EtherWAN Visio Toolkit + demo
Learn the correct wiring and power-up sequence for an industrial Ethernet switch and DC power supply. From cabling to first boot—new users can get it done confidently.

VLAN Segmentation — Better Performance, Stronger Security
Get the core VLAN logic on managed switches—then use it to segment real networks..
With VLAN segmentation, you can plan topology more flexibly while improving security and operational efficiency for ITS, industrial control networks, and enterprise edge deployments.
👉 Watch the VLAN demo
See the difference between trunk and access ports, then fix VLAN issues between switches.
Learn how tagged and untagged traffic behaves across switches, so VLANs stay clean and separated.

Smart Operations | Automated Recovery for Remote Sites
Traffic-based monitoring triggers automatic recovery, so PoE devices can reboot and recover fast from intermittent dropouts.
Enable PoE Watchdog in the management UI to monitor devices 24/7 and auto-reboot remote endpoints—ideal for IP cameras, unmanned sites, and large deployments.
👉 Watch PoE Watchdog in action
Traffic-based monitoring triggers automatic recovery, so PoE devices can reboot and recover fast from intermittent dropouts.
Learn what PoE Watchdog is, how it helps maintain network reliability by automatically rebooting unresponsive devices, and follow our step-by-step guide to configure it on your EtherWAN device. We'll cover accessing the web interface, navigating to PoE settings, enabling PoE Watchdog, configuring ping settings, and saving your changes. Plus, we'll share tips to get the best out of your PoE Watchdog.

Alpha Ring lab: 15ms failover for video and critical traffic.
This video shows how Alpha Ring redundancy works and how to set it up. If any node in the network fails, traffic can fail over in about 15ms—ideal for video surveillance, transportation, and industrial Ethernet networks that need high uptime.
How do you keep video stable—and how do you test failover the right way?
This walkthrough covers an end-to-end surveillance network build: switch configuration, redundancy topology, and side-by-side failover testing. The focus is system-level design so video keeps running even when devices or links fail—ideal for transportation monitoring, public areas, and industrial sites.
