Allied Telesis AT-IE340-20GP-80 – 16-Port Industrial PoE+ Layer 3 Switch 4x SFP+

Product Overview

The Allied Telesis IE340-20GP-80 is an Allied Telesis IE340 industrial PoE+ Layer 3 switch with 16 ports of 10/100/1000Base-T PoE+ plus 4x SFP+ uplinks, engineered for demanding industrial, transportation, and outdoor network deployments. With double the PoE port count of the IE340-12GP (8 ports), the IE340-20GP-80 is the preferred choice when powering 16 devices such as IP cameras, access control readers, or industrial sensors from a single switch. The unit is DIN-rail mountable, fanless, and rated for a wide operating temperature range of -40°C to +75°C, making it suitable for factory floors, roadside cabinets, and railway installations.

Product Description

The Allied Telesis IE340 industrial PoE+ Layer 3 switch 16-port model provides 240W total PoE budget across 16 IEEE 802.3at PoE+ ports, each delivering up to 30W to connected devices. Layer 3 routing capabilities (static routing and RIPv1/v2) allow the IE340-20GP-80 to serve as a routing node at the network edge, reducing dependence on upstream router infrastructure. All 4 SFP uplinks support both Gigabit and Fast Ethernet SFPs, enabling phased migration from legacy 100FX infrastructure to Gigabit fiber. EPSRing and ITU-T G.8032 ERPS ring protocols provide sub-50ms failover recovery, meeting the high-availability requirements of industrial automation and transportation signaling systems. The fanless design eliminates moving parts and reduces maintenance in harsh environments. Modbus/TCP integration enables real-time monitoring and control from existing SCADA and factory management systems. AMF management allows zero-touch provisioning and automated configuration backup, while Vista Manager EX provides graphical network visibility. IEEE 802.1X port authentication and role-based access control secure the network edge against unauthorized connections. The switch supports OpenFlow v1.3 for SDN-ready deployments.

Frequently Asked Questions

Q: How does the IE340-20GP-80 differ from the IE340-12GP?

The IE340-20GP-80 provides 16x PoE+ copper ports compared to 8x on the IE340-12GP, making it the right choice when powering more than 8 end devices from a single switch in industrial environments.

Q: What is the total PoE power budget on the IE340-20GP-80?

The IE340-20GP-80 supports a 240W configurable PoE budget. Power is allocated dynamically based on actual consumption of connected devices, maximizing the number of simultaneously powered ports.

Q: Can the IE340-20GP-80 operate in outdoor enclosures in extreme cold?

Yes. The fanless design and -40°C to +75°C operating range make it suitable for outdoor roadside cabinets, railway trackside installations, and other extreme-temperature environments.

Q: Does the IE340-20GP-80 support integration with SCADA systems?

Yes. Modbus/TCP support enables direct integration with SCADA, DCS, and distributed control systems for real-time network monitoring and automation in industrial environments.

Q: What fiber SFPs are compatible with the 4 uplink ports?

The IE340-20GP-80 SFP slots support both Gigabit (1000Base-X) and Fast Ethernet (100FX) SFPs, allowing connection to legacy fiber infrastructure while supporting future Gigabit upgrades.

Q: Where can I purchase the AT-IE340-20GP-80?

The AT-IE340-20GP-80 is available through Creation Networks at creationnetworks.net, an authorized Allied Telesis reseller.
