Allied Telesis AT-IE340L-18GP-80 – Industrial L3 PoE+ Switch, 16x GbE + 2x SFP

Product Overview

The Allied Telesis IE340L-18GP industrial PoE+ Layer 3 switch (AT-IE340L-18GP-80) delivers 16 ports of IEEE 802.3at PoE+ Gigabit Ethernet and 2 SFP fiber uplinks in a compact, fanless DIN-rail or wall-mountable enclosure built for harsh industrial and outdoor environments. As an industrial Layer 3 managed switch for manufacturing and transportation networks, the IE340L-18GP is fully rated for wide operating temperature ranges, making it suitable for factory floors, roadside cabinets, rail signaling infrastructure, and smart city deployments. With support for Allied Telesis AMF and OpenFlow v1.3, this switch is an ideal choice for network engineers requiring a ruggedized DIN-rail PoE+ switch with Layer 3 routing in IIoT, process control, and physical security applications.

Product Description

The AT-IE340L-18GP-80 is part of the Allied Telesis IE340 series, a purpose-built family of industrial Ethernet switches engineered to operate continuously in environments where commercial-grade hardware fails. The fanless design eliminates moving parts, reducing mechanical failure risk and enabling silent operation in noise-sensitive or sealed enclosures. All 16 copper ports support PoE+ (IEEE 802.3at) at up to 30W per port, enabling remote powering of IP cameras, wireless access points, industrial sensors, and VoIP endpoints without separate power injectors. The 2 SFP uplink slots support both Gigabit and Fast Ethernet SFPs, providing flexible fiber connectivity to aggregation switches or backbone infrastructure. Layer 3 switching capabilities include static routing and dynamic routing protocols, enabling inter-VLAN routing without a dedicated router at remote sites. Modbus/TCP support allows the IE340L-18GP to integrate directly with factory SCADA systems and programmable logic controllers (PLCs) for real-time monitoring and automation. The IE340L series is qualified for manufacturing, process control, railway (Telco and signaling), roadway traffic control, and smart city applications. Network resiliency is ensured through EPSRing and ITU-T G.8032 ring protection with sub-50ms recovery times. IEEE 802.1X port-based authentication and DHCP snooping secure network access at the industrial edge, while ACLs provide granular traffic filtering. Management is handled through AlliedWare Plus with support for the Allied Telesis Autonomous Management Framework (AMF) for centralized, zero-touch provisioning and configuration recovery across distributed industrial sites.

Key Features

• Modbus/TCP Integration — Native Modbus/TCP support enables direct integration with SCADA systems, PLCs, and industrial automation platforms.
• Sub-50ms Ring Recovery — EPSRing and ITU-T G.8032 ring protection provide network resilience with recovery times under 50 milliseconds.
• Configurable PoE Power Budget — Dynamic PoE power allocation adjusts per-port power based on actual device draw, maximizing PSU efficiency.
• IEEE 802.1X Authentication — Port-based authentication prevents unauthorized devices from accessing the industrial network.
• AMF Support — Allied Telesis Autonomous Management Framework automates configuration backup, recovery, and zero-touch provisioning across distributed sites.
• OpenFlow v1.3 Ready — SDN-ready architecture supports OpenFlow v1.3 for software-defined network control.
• IPv6 Ready — Certified IPv6 Ready for forward compatibility with next-generation industrial network addressing.

Typical Applications

• Manufacturing and process control networks requiring ruggedized DIN-rail switching with PoE for connected sensors and cameras.
• Railway signaling and trackside telecommunications infrastructure subject to wide temperature variation and vibration.
• Roadway and traffic control cabinets where a compact, fanless L3 switch must power and connect roadside ITS equipment.
• Outdoor smart city deployments including connected lighting, environmental monitoring nodes, and public Wi-Fi APs.
• Physical security networks in industrial facilities requiring PoE for IP cameras and access control panels at the network edge.
• Oil, gas, and utility substations where harsh environments demand industrial-rated network hardware.

Technical Specifications

Frequently Asked Questions

Q: What industrial certifications does the IE340L-18GP hold?

The IE340L series is qualified for manufacturing, automation, process control, railway transportation (Telco and signaling), roadway transportation (traffic control), and smart city deployments. It carries IPv6 Ready certification and meets environmental compliance standards.

Q: What is the total PoE power budget of the AT-IE340L-18GP-80?

The PoE power budget is determined by the external Power Supply Unit (PSU) connected to the switch. The IE340L-18GP supports configurable PoE budgets that align with the real PSU capacity, and power is allocated dynamically based on actual per-port device draw.

Q: Can the IE340L-18GP route between VLANs without a separate router?

Yes. The IE340L-18GP operates at Layer 3, supporting inter-VLAN routing via static routes and dynamic routing protocols, eliminating the need for a dedicated router at remote industrial sites.

Q: How does the switch integrate with industrial SCADA systems?

The IE340L-18GP supports Modbus/TCP, which enables direct integration with factory management tools, SCADA systems, and programmable logic controllers (PLCs) for real-time network monitoring within industrial automation environments.

Q: What SFP modules are supported in the uplink slots?

The two SFP slots support both 100FX (Fast Ethernet) and 1000X (Gigabit Ethernet) SFP transceivers, allowing organizations to connect to existing 100FX infrastructure while planning migration to Gigabit fiber.

Q: What mounting options are available?

The AT-IE340L-18GP-80 includes DIN rail and wall mount kits in the box, supporting both standard DIN rail installation in control cabinets and direct wall mounting in junction boxes or equipment rooms.
