Allied Telesis AT-IE340-12GT-980 8X 10/100/1000T 4X 100/1000X SFP INDUSTRIAL ETHERNET LAYER 3

Product Overview

The Allied Telesis AT-IE340-12GT-980 is a TAA-compliant industrial Layer 3 managed switch offering 8 x 10/100/1000T copper ports and 4 x 100/1000X SFP fiber slots in a DIN rail and wall-mountable form factor rated for -40°C to +75°C operation. This is a non-PoE switch — it does not deliver Power over Ethernet on any port; engineers requiring PoE on the IE340 platform should specify the IE340-12GP model instead. The AT-IE340-12GT-980 industrial Ethernet Layer 3 switch no PoE variant carries the -980 suffix, which includes the AlliedWare Plus Network Coverage subscription for ongoing software support. It is designed for manufacturing, process control, transportation signaling, traffic management, and smart city infrastructure where standard commercial switches cannot withstand thermal, vibration, or electrical transient conditions.

Product Description

The IE340-12GT-980 delivers 24Gbps switch fabric and 17.8Mpps forwarding throughput across its 12 ports (8 copper + 4 SFP), with support for 16K MAC addresses, 4K VLANs, 9KB jumbo frames, and 8 QoS priority queues. The switch supports 511 Layer 2 and 256 Layer 3 multicast groups, making it suitable for industrial multicast applications such as SCADA polling and video surveillance distribution. Alarm input and output ports allow direct integration with industrial control panel signaling systems. The wide DC input voltage range (18V to 57V DC) supports diverse industrial power architectures including 24VDC process control panels and 48VDC telecom power systems. Modbus/TCP support enables native integration with factory management and SCADA platforms without requiring a separate protocol gateway. Allied Telesis Autonomous Management Framework (AMF) automates configuration management and provides zero-touch recovery for failed nodes — particularly valuable in remote or unmanned industrial installations. The fanless all-metal (sheet metal and aluminum) enclosure eliminates mechanical failure risk in dusty or vibration-prone environments. The -980 suffix distinguishes this SKU from the -80 variant; both share the IE340-12GT base model hardware but differ in PSU/power configuration and regional variant designation — verify the correct suffix for your power environment. Note that neither IE340-12GT variant provides PoE; for PoE+ on industrial ports, the IE340-12GP is the appropriate product. Physical dimensions: 6" H x 3.6" W x 5.5" D, with DIN rail and wall mount kits included.

Key Features

• No PoE — Non-PoE Industrial Switch — The IE340-12GT-980 does not deliver Power over Ethernet. Specify IE340-12GP for PoE+ capability on the IE340 platform.
• -40°C to +75°C Operating Temperature — Rated for extreme thermal environments including outdoor enclosures, factory floors, and transportation applications.
• 8 x 10/100/1000T Copper + 4 x 100/1000X SFP — Flexible copper-plus-fiber port configuration for mixed access and uplink needs.
• TAA Compliant — Meets Trade Agreements Act requirements for government infrastructure projects and critical national infrastructure procurement.
• Wide DC Input (18V–57V) — Supports 24VDC and 48VDC industrial power systems; dual power input for redundancy.
• Alarm I/O Ports — Direct integration with industrial panel alarm systems for environmental monitoring and fault signaling.
• Modbus/TCP — Native industrial protocol support for SCADA and factory automation system integration.
• Fanless Metal Enclosure — Sheet metal and aluminum construction; no moving parts for maximum reliability in harsh environments.
• AMF + AlliedWare Plus — Enterprise-grade management with zero-touch provisioning for remote and unmanned industrial sites.

Typical Applications

• Manufacturing automation and process control network infrastructure
• Railway signaling and trackside communications (EN 50121 environments)
• Road traffic management and intelligent transportation systems
• Outdoor utility and substation Ethernet networking in harsh thermal environments
• Smart city sensor networks and municipal infrastructure control
• Oil and gas field data acquisition where wide temperature and DC power ranges are required

Frequently Asked Questions

Q: Does the IE340-12GT-980 support PoE?

No. The IE340-12GT-980 is a non-PoE switch. None of its 8 copper ports deliver Power over Ethernet. If you require PoE+ capability on the IE340 platform, the IE340-12GP model provides PoE+ on the copper ports.

Q: What is the difference between the IE340-12GT and the IE340-12GP?

The IE340-12GT has standard Gigabit Ethernet copper ports with no PoE. The IE340-12GP variant provides PoE+ (IEEE 802.3at) power delivery on its copper ports. Both share the same IE340 industrial chassis, temperature rating, and AlliedWare Plus feature set.

Q: What is the difference between the IE340-12GT-980 and the IE340-12GT-80?

Both are non-PoE IE340-12GT base model switches. The -980 and -80 suffixes denote different PSU configurations and regional variant designations. Contact Creation Networks to confirm which variant matches your power infrastructure requirements before ordering.

Q: What power supply voltages does the IE340-12GT-980 accept?

The switch accepts DC input in the range of 18V to 57V DC, supporting standard 24VDC process control and automation power buses as well as 48VDC telecom-grade power systems. Dual power inputs are supported for redundancy.

Q: Is the IE340-12GT-980 suitable for outdoor deployment?

The -40°C to +75°C operating temperature range makes it suitable for outdoor enclosures in most climate zones when housed in a weatherproof cabinet. Direct outdoor exposure without an enclosure is not recommended.

Q: Does the IE340-12GT-980 support ring topology for redundancy?

Yes. The switch supports Allied Telesis EPSRing and IEEE G.8032 Ethernet Ring Protection, providing fast sub-50ms failover for ring network topologies common in industrial and transportation deployments.

Q: Is Modbus/TCP supported natively?

Yes. Modbus/TCP is supported natively through AlliedWare Plus, enabling direct integration with SCADA systems and factory management platforms without an external protocol converter.
