Allied Telesis IE340-20GP Layer 3 Switch

The Allied Telesis IE340-20GP Layer 3 Switch is purpose-built for industrial automation and control networks where every millisecond of data matters. This switch blends rugged reliability with intelligent networking to deliver dependable access, routing, and management across demanding environments such as factories, process lines, and smart manufacturing facilities. With 20 high-density Ethernet ports and flexible uplink options, the IE340-20GP provides the performance necessary for real-time control, sensor fusion, and multi-stream data flows, while maintaining a straightforward management experience for IT and OT teams alike. Its design prioritizes low latency, high availability, and scalable capacity so that industrial applications—from machine automation to remote monitoring—operate with precision and confidence.

• Industrial-grade performance for real-time control: The IE340-20GP is engineered to handle time-sensitive traffic with low latency and high throughput. It features Layer 3 routing capabilities that enable efficient traffic segmentation between automation subsystems, control stations, and supervisory devices. By combining fast switching with intelligent routing, it reduces congestion on critical control paths and ensures predictable responsiveness for PLCs, HMIs, and SCADA components.

  In practice, this means you can implement static and dynamically learned routes to optimize data paths, minimize jitter, and maintain deterministic behavior essential for industrial processes.

• Robust security and reliable management: Security is built into the core of the IE340-20GP. Strategies such as access control lists (ACLs), secure device hardening, and robust authentication help protect critical control networks from unauthorized access. The switch supports secure remote management through industry-standard protocols, enabling administrators to monitor, configure, and troubleshoot without exposing the network to risk. Comprehensive logging and alerting ensure operators stay informed of anomalous activity or component faults even in remote locations.

  For maintainability, the IE340-20GP integrates with existing IT/OT management ecosystems via SNMP and standardized management interfaces, reducing mean time to repair and simplifying ongoing network governance.

• Flexible connectivity and scalable network design: This model provides 20 high-density Ethernet ports for versatile access to industrial devices, sensors, and controllers. It also offers flexible uplink options to connect to core switches, data aggregation points, or fiber-backed backbones. The IE340-20GP supports VLANs and advanced QoS to separate traffic by priority, ensuring critical control data takes precedence over less time-sensitive monitoring or administrative traffic. The switch is designed to grow with your network, supporting expansions through modular uplinks and efficient IP routing to accommodate evolving industrial architectures.

  Whether you’re segmenting traffic by production line, workstation, or application, the IE340-20GP delivers consistent performance and predictable behavior across diverse workloads.

• Rugged industrial design with reliable operation: Built for harsh environments, the IE340-20GP features a durable enclosure suitable for DIN-rail mounting and industrial installation contexts. It is designed to endure wide operating temperature ranges, vibration, and dust exposure typical of factory floors and industrial facilities. The switch emphasizes reliability and availability, providing hardware features that support uninterrupted operation, such as redundancy considerations in power delivery and resilient cooling strategies depending on deployment.

  This combination of rugged hardware and intelligent software helps minimize downtime and supports continuous production, even under challenging conditions.

• Intuitive management and seamless integration: The IE340-20GP offers both a web-based graphical user interface and a command-line interface for flexible setup and ongoing administration. It includes standard industry management features such as SNMP for monitoring, device alarms, and scalable configuration backups. The switch’s architecture is oriented toward easy integration with supervisory systems, asset inventories, and automation platforms, enabling operations teams to deploy, monitor, and adjust network behavior from a single console.

  Administrators benefit from straightforward firmware updates, clear status dashboards, and helpful diagnostic tools that support rapid fault isolation and performance tuning in dynamic industrial environments.
