Advantech EKI-1526 Dual LAN Redundancy Full Configuration Guide

The EKI-1526 supports Master-Backup dual LAN redundancy with switchover time <1 segundo. After enabling via Web UI, it automatically detects link faults and performs seamless failover to ensure uninterrupted industrial communication.

1. Dual LAN Redundancy Working Principle

The EKI-1526 is equipped with two independent Ethernet ports (LAN1/LAN2) and independent MAC addresses:

Master Port: Carries all network traffic under normal operation

Backup Port: Monitors master port status in real time and takes over only when master port fails

Switchover Mechanism: Automatically switches to backup port upon LAN link down (cable disconnection / switch failure), switchover time <1 second with no data loss

Restore Mechanism: After master port recovers, configurable for auto switch back or remain on backup port

2. Hardware Connection Preparation

Recommended Topologies (Avoid Single Point of Failure)

Hardware Wiring Steps

1. Power off the device, connect serial devices and power supply
2. Connect LAN1/LAN2 to switches (dual switches recommended)
3. Encendido; check indicators: PWR steady on, both LAN LINK lights flashing normally
4. Detailed Web Configuration Steps
5. Basic Network Settings (Obligatorio)
6. Set PC static IP: 192.168.1.incógnita (same segment as device default)
7. Browser access default IP: 192.168.1.1, login: `admin/admin`
8. Go to Ethernet Configuration → Ethernet 1: Set master port IP, subnet mask, gateway
9. Go to Ethernet Configuration → Ethernet 2: Set backup port IP (same segment recommended, p.ej. 192.168.1.2), subnet mask, gateway
10. Click Save, device auto restarts (acerca de 1 minuto)
11. Enable Dual LAN Redundancy (Core Config)
12. Log in Web UI again after reboot
13. Enter Network → Redundancy
14. Check Enable Dual LAN Redundancy
15. Select Redundancy Mode:

Master-Backup (Por defecto): LAN1 as master, LAN2 as backup, auto failover upon fault

Load Balance: Both ports work simultaneously for traffic sharing (supported by partial firmware)

5. Set Switch Back Mode:

Auto: Automatically switch back to master after recovery (Por defecto)

Manual: Stay on backup port; manual switch required after master recovery

6. Set Detection Interval: Por defecto 1 segundo, adjustable 500ms~10s (1s recommended)
7. Click Save, redundancy takes effect immediately
8. Advanced Configuration (Opcional)

4. Redundancy Function Test
5. Link Fault Test
6. Normal status: Web Status → Network Status shows LAN1 Active, LAN2 Standby
7. Unplug LAN1 cable:

Device indicator: LAN1 off, LAN2 steady on

Web status updates: LAN2 becomes Active, switchover <1s

Verify serial communication via Virtual COM / Modbus TCP, no interruption

3. Reconnect LAN1 cable:

Auto Mode: LAN1 resumes Active, LAN2 becomes Standby

Manual Mode: Remain on LAN2; manual switch required in Web UI

2. Switch Failure Test
3. Power off the switch connected to master port
4. Device switches to backup port within 1 segundo
5. Restore master switch power and verify switchback works normally
6. Solución de problemas comunes

6. Configuration Mnemonic

> Three steps for dual LAN redundancy: set IP first, enable redundancy second;

> Dual switches avoid single point; always verify failover after config.

1. Hardware Selection: Critical sites choose dual switches; ordinary sites choose single switch dual port
2. IP Planning: Master and backup ports recommended same network segment for easy management & switchover
3. Selección de modo: Industrial control prioritizes Master-Backup; data collection can use Load Balance
4. Switchback Policy: Unattended sites select Auto; manual intervention sites select Manual
5. Test Validation: Perform link failover test after configuration to ensure reliable redundancy in actual faults

EKI-1526 dual LAN redundancy can be quickly configured via Web interface. The core is enabling redundancy and correctly setting master/backup IP and switchover policy. Cooperating with dual-switch topology, it effectively eliminates single-point faults in industrial networks and ensures high reliability of serial device communication. Full functional verification is recommended after deployment.
