Allied Telesis AT-IE340-12GP-80 – Industrial PoE+ Layer 3 Switch 8-Port

Product Overview

The Allied Telesis AT-IE340-12GP-80 is a fully managed Allied Telesis IE340 industrial PoE+ Layer 3 switch engineered for mission-critical deployments in harsh physical environments. Featuring 8 x 10/100/1000T IEEE 802.3at PoE+ copper ports and 4 x 100/1000X SFP uplinks, this industrial-grade managed gigabit PoE+ switch delivers 240W of total PoE budget with a 24 Gbps switch fabric to power and connect IP cameras, industrial IoT devices, and access points in locations where standard commercial switches cannot operate. With a rated operating temperature of -40°C to 75°C and DIN rail or wall mount form factor, it is a purpose-built DIN rail industrial Ethernet switch for manufacturing and transportation networks.

Product Description

The Allied Telesis IE340-12GP is a member of the IE340 Series of industrial managed switches built to meet the rigorous demands of factory floors, transportation systems, utility substations, and outdoor enclosures where commercial networking equipment cannot reliably operate. The switch delivers a 24 Gbps switch fabric with a 17.8 Mpps forwarding rate, a 16K MAC address table, and support for 4,096 VLANs, giving network engineers the full feature density of an enterprise-class Layer 3 device in a hardened industrial chassis. All 8 copper RJ45 ports support IEEE 802.3at PoE+ at up to 30W per port, with a 240W total PoE budget for powering high-density IP camera arrays, VoIP infrastructure, or wireless access points in locations where separate power runs are impractical. The four 100/1000X SFP uplink slots allow fiber or copper uplink modules for integration into the wider campus or plant backbone. The extended temperature range of -40°C to 75°C covers both extreme cold-weather outdoor deployments and high-ambient industrial enclosures. Integrated alarm input and output ports allow the switch to participate in plant-wide supervisory control and data acquisition (SCADA) alarm systems, notifying operators of network or environmental events. Layer 3 switching support enables inter-VLAN routing on-device, eliminating the need for a separate router in segmented plant networks. The switch supports 9KB jumbo frames, 8 QoS priority queues for voice and video traffic prioritization, and 511 Layer 2 / 256 Layer 3 multicast groups for industrial multicast protocols. DIN rail and wall mount kits are included in the box, enabling flexible installation in standard industrial control cabinets.
