Allied Telesis IE340-12GP Industrial 8-Port Gigabit PoE+ Layer 3 Switch with 4 x SFP
PRODUCT DESCRIPTION
Allied Telesis IE340-12GP Industrial PoE+ Layer 3 Switch - Local Warranty
Hardened for Factories, Roadsides and Outdoor Cabinets
The IE340-12GP is a fanless, IP30-rated industrial switch in an aluminium and sheet-metal housing. It runs from -40°C to 75°C, mounts on a DIN rail or a wall, and meets industrial standards for vibration, shock and electrical noise, so it can sit in control cabinets and enclosures where office switches would fail.
PoE+ for Cameras, Access Points and IoT Devices
All eight Gigabit copper ports can source IEEE 802.3at PoE+ at up to 30W each from a 240W PoE budget. Dynamic PoE power allocation shares that budget efficiently, and Continuous PoE helps keep powered endpoints such as IP cameras online.
Layer 3 Routing and Fast-Recovering Rings
Beyond Layer 2 switching, the IE340 supports static and dynamic routing including RIP, OSPF, BGP and ECMP (advanced routing via the IE340 Premium licence). EPSRing, ITU-T G.8032 ERPS and MRP build protected ring topologies that can recover in as little as 50ms.
Made for Industrial Automation
PROFINET certification, Modbus/TCP and IEEE 1588 PTP Transparent Clock support make the IE340-12GP suited to automation and control networks, while NETCONF/RESTCONF, OpenFlow v1.3 and AMF Plus bring centralised management and automation.

Typical Deployments
Manufacturing lines, transportation, physical security and IP surveillance, building automation and facility management, and smart-city cabinets where PoE devices need a rugged, fanless edge switch.
Selection Tip
Choose the IE340-12GP for 8 PoE+ ports with 4 SFP uplinks. If you do not need PoE, the IE340-12GT has the same port layout without PoE. For 16 PoE+ ports choose the IE340-20GP, and for environments with corrosive contaminants choose a conformal-coated /C model.

Frequently Asked Questions — Allied Telesis IE340-12GP
What does the -80 in AT-IE340-12GP-80 mean?
It is the standard country-of-origin version. The -980 suffix is the TAA-compliant version.
What power input does it need?
18~57V DC through redundant inputs. To source PoE+ (802.3at Type 2) the input must be 54Vdc; 48Vdc enables standard PoE (Type 1). The power supply is purchased separately.
How much PoE power is available?
Up to 30W per port on all 8 copper ports, from a total PoE budget of 240W.
Can it run outdoors or in hot cabinets?
It is rated for -40°C to 75°C operation with a fanless, IP30 design. It still needs to be installed in a suitable enclosure.
What warranty do I get?
Supplied by SourceIT with local warranty and a GST invoice.
