Steel Plant Network Deployment
In one of Asia’s largest steel manufacturing facilities, EtherWAN deployed a layered network architecture across the core, distribution, and access layers to improve network security, device stability, and operational efficiency.
Designed for high-temperature and high-EMI industrial environments, the solution integrates Layer 2/Layer 3 industrial managed switches , a fiber backbone, ERPS ring redundancy , and dual power redundancy to strengthen transmission stability and network reliability, while supporting AI vision, equipment monitoring, automation control, and 24/7 smart manufacturing operations.

Core Networking
Supports Layer 3 routing and VLAN segmentation for stable, secure connectivity across large-scale industrial networks.Network Management
With eVue Network Management Software , teams can monitor devices, visualize topology, and simplify troubleshooting across large industrial facilities.
Network Redundancy
With Alpha-Ring , OSPF, and VRRP redundancy mechanisms, industrial networks remain connected with reduced downtime risk.
This steel plant deployment faced high temperatures, high EMI, dust, and large-scale device connectivity requirements. EtherWAN deployed industrial managed switches with wide-temperature operation, ERPS ring redundancy, and dual power input to keep network communication stable in harsh industrial environments.
Challenges
- High temperature, high EMI, and dusty environments
- Unstable links that may disrupt production
- Redundancy required to reduce disconnection risks
- Core switches must support reliability and future expansion
Solution
Core and Distribution Layers use 24-port industrial managed switches supporting Layer 2/Layer 3 network architecture, wide-temperature operation (-40°C to 75°C), and dual power redundancy to improve backbone stability and reliability in large factories.
At the production line, EtherWAN integrated IG5 Rack Series industrial managed switches with Alpha-Ring redundancy to reduce disconnection risks, improve operational efficiency, and keep critical equipment and production processes running reliably.
Core Layer
The EG97244 Series is designed for industrial backbone networks that require 10G fiber uplinks, Layer 3 routing, and high-density device aggregation across plants, floors, and production areas. With multiple 1G TX ports, four 10G fiber uplinks, OSPF, VRRP, and built-in Layer 3 management, EG97244 supports high-speed core-layer data aggregation and high-availability network designs.
The fanless, dust-resistant design and -40°C to +75°C operating temperature range help maintain stable performance in high-temperature, dusty, and long-running industrial environments. For smaller sites, IG5 Layer 3 switches provide management features with flexible deployment.
Distribution Layer
The IG5 Rack Series is an industrial rackmount switch designed for high-EMI, wide-temperature, and 24/7 harsh environments.
Flexible Ethernet and fiber port combinations support different distance, bandwidth, and redundancy requirements. With Redundant Pair coupling and Alpha-Ring redundancy, the series helps restore connectivity quickly during network events and reduce communication interruption risks in power, transportation, and industrial control applications.
For power and time-synchronization applications, IG5 Rack Series supports IEEE 1588v2 precision timing and complies with IEC 61850-3/IEEE 1613 standards for synchronization accuracy, EMI immunity, and environmental reliability. Smaller sites can also use compact vertical models or PoE Ethernet switches with PoE PD cascading for flexible network deployment.
