Description
🔍 Product Overview
The Westermo L110-F2G is an industrial-grade, layer 2/3 routing Ethernet switch engineered for mission-critical infrastructure and harsh automation environments. Part of the robust Lynx series, this compact device features a combination of fixed copper twisted-pair ports and dual SFP fibre-optic slots (F2G), enabling flexible, long-distance network extensions. Powered by Westermo’s proprietary WeOS (Westermo Operating System), it delivers advanced cybersecurity features, static routing, firewall functionality, and ultra-fast ring recovery protocol (FRNT) to ensure continuous network uptime in rail, energy, and water treatment utilities.

🚀 Application Areas
- Substation Automation: Operating reliably under high electromagnetic interference (EMI) environments compliant with IEC 61850-3.
- Railway and Trackside Systems: Deploying alongside track signal controls due to its broad thermal range and vibration resistance.
- Water and Wastewater Plants: Linking remote telemetry units (RTUs) across expansive geographical areas using fiber rings.
- Heavy Industrial PLC Networking: Interfacing manufacturing cells with enterprise IT layers using secure firewall segregation.
📖 Product Usage Instructions
The L110-F2G features a heavy-duty industrial aluminum housing designed to snap directly onto standard TS35 DIN rails. For optimal passive heat dissipation, mount the unit vertically with at least 25 mm of clearance above and below the cooling vents. When utilizing the SFP slots, ensure the optical transceivers match your fiber optic core layout (Single-mode vs. Multi-mode). Ground the chassis securely to the local control panel earth bus via the dedicated grounding screw to protect sensitive communication transceivers from static discharge.
🌐 Communication Configuration Steps
- IP Address / Web Management Setup: Out of the box, assign a temporary static IP address to your commissioning laptop within the default factory subnet (typically
192.168.2.x). Connect an Ethernet cable to Port 1, open a web browser, and type in the factory default IP address192.168.2.200to access the WeOS management interface. - Station Number / Node VLAN Identity: Create Virtual Local Area Networks (VLANs) within the switch management console to assign specific ID numbers and isolate control systems (e.g., VLAN 10 for PLC logic, VLAN 20 for HMI telemetry).
- Baud Rate / Link Speed Negotiation: The copper ports feature auto-MDI/MDI-X and automatic speed negotiation. For specialized legacy infrastructure links, navigate to the port configuration tab to manually lock speeds at 10 Mbps or 100 Mbps and force Full/Half Duplex parameters.
⚡ Power-Up & Commissioning Flow
- Redundant Power Wiring: Connect a dual-source power layout to the pluggable terminal block, utilizing two separate power supplies to provide automatic backup.
- Voltage Verification: Confirm the input voltage matches the device’s broad multi-range capabilities (typically 19V to 60V DC nominal supply).
- Boot Verification: Apply power. The front panel “ON” indicator LED will blink amber during internal memory loading and self-test execution, switching to a solid green state when WeOS is fully operational.
- Ring Topology Validation: If utilizing a Westermo FRNT network ring, connect the fiber paths and check that the designated ring master LED indicates a healthy, unfragmented loop state.
✅ Initial Operation Checklist
- Is the DIN-rail grounding foot clamping firmly to an unpainted, clean section of the grounded backplane panel?
- Are all unpopulated SFP slots sealed with protective dust covers to protect internal optical paths from airborne oil mist?
- Has the default factory password been replaced with a secure custom string within the WeOS configuration?
- Do the port linkage LEDs flash rapidly to confirm active ingress/egress data streaming?
❓ Common Questions (Q&A)
Q: What does a solid red or flashing “FRNT” or “Alarm” LED indicate on the faceplate?
A: A red alarm indicator indicates a structural network failure. This can point to a physically broken fiber line within the redundant ring, an identical IP address collision on the subnet, or a failure in one of the redundant DC power supplies.
Q: Can I backup and restore configuration parameters without using a PC?
A: Yes, WeOS supports an optional configuration backup accessory (Westermo configuration memory device) that plugs directly into the local console port, allowing maintenance teams to instantly flash parameters to a replacement switch in the field.
Q: How do I restore the L110-F2G to its factory defaults if the login credentials are forgotten?
A: Locate the small factory reset button recess on the front panel. Using a fine-tipped tool, depress and hold the button for approximately 10 seconds while cycling the auxiliary power feed off and on again to clear the internal flash memory back to base settings.
