Cisco Catalyst IE-3400H-16T-E 16-Port Gigabit Ethernet IP67 M12 Industrial Switch, Network Essentials
- Catalyst IE3400 Heavy Duty, 16 x GE M12 interfaces, IP67, with Network Essentials license
Overview
The Cisco Catalyst IE3400 Heavy Duty Series is Cisco's IP66/IP67-rated industrial switch line, delivering capabilities similar to the DIN-rail IE3400 Rugged Series in places with heavy exposure to dust and water, using M12 connectors and wall mounting with no housing cabinet. The IE-3400H-16T-E is the 16-port Gigabit Ethernet configuration at the Network Essentials tier. At the Network Essentials tier it provides Layer 2 switching with inter-VLAN and IPv4 static routing. The otherwise-identical Network Advantage IE-3400H-16T-A adds full dynamic routing and SGT/SGACL Cisco TrustSec segmentation. It runs IOx edge applications and supports Cisco Cyber Vision and Secure Equipment Access, and because it has a single power input and no stacking, resiliency is built with REP, MRP, DLR, and PRP ring topologies at the network layer.
Technical Details
The Cisco Catalyst IE-3400H-16T-E is a Layer 2+ managed, fanless, IP66/IP67-rated industrial switch with 16 Gigabit Ethernet M12 (X-coded) ports, running Cisco IOS XE with the perpetual Network Essentials license. It is sealed against dust and water and is wall-mounted without a housing cabinet. It forwards at line rate on all ports for all packet sizes and holds up to 16,000 MAC addresses. It carries no Power over Ethernet, and all connectivity is over fixed M12 copper ports with no SFP or fiber uplinks. It supports inter-VLAN and IPv4 static routing; dynamic routing and SGT/TrustSec segmentation are not included at the Network Essentials tier. Operating temperature is -40 °C to +75 °C with airflow, and power is a single DC input over an M12 mini-change connector. It is used for secure wired connectivity of industrial devices such as PLCs, HMIs, drives, cameras, and sensors directly on factory floors, trackside, and outdoor sites exposed to dust and water.
Best For
The IE-3400H-16T-E suits harsh, wet, or dusty industrial sites such as factory floors, trackside cabinets, water treatment, and outdoor installations that connect industrial devices such as PLCs, HMIs, drives, and cameras over 16 Gigabit Ethernet M12 ports without needing a sealed housing cabinet. Its IP66/IP67 sealing, M12 connectors, fanless design, and -40 °C to +75 °C operating range let it mount directly in the environment. The Network Essentials license fits Layer 2 and static-routed segments; sites needing TrustSec segmentation or dynamic routing should order the Network Advantage IE-3400H-16T-A instead.
Not suitable if:
- you need SGT/SGACL Cisco TrustSec segmentation or dynamic routing such as OSPF or BGP, since those require the Network Advantage IE-3400H-16T-A rather than this Network Essentials model
- you need to power endpoints over the switch, since the IE3400 Heavy Duty models are data-only and do not source Power over Ethernet
- you need SFP fiber uplinks or RJ45 ports, since all ports are fixed M12 copper connectors
- you are installing in a protected cabinet and do not need IP67 sealing, since the DIN-rail Catalyst IE3400 Rugged Series covers that at a smaller size

FAQ
Does the Cisco Catalyst IE-3400H-16T-E support PoE?
No. The Cisco Catalyst IE-3400H-16T-E is a data-only switch, and its M12 ports do not source Power over Ethernet. It cannot power devices such as IP cameras, wireless access points, or IP phones over its ports. Cisco offers a separate IP67-rated DC-DC power supply accessory for the platform, but the switch itself does not deliver PoE to connected endpoints.
What are the IP rating and environmental specifications of the IE-3400H-16T-E?
The Cisco Catalyst IE-3400H-16T-E is rated IP66 and IP67, meaning it is dust-tight and protected against water submersion, so it can be wall-mounted directly in harsh environments without a housing cabinet. It uses M12 connectors (D-coded for Fast Ethernet, X-coded for Gigabit Ethernet, and a mini-change connector for power), is fanless and convection-cooled with no moving parts, and operates from -40 °C to +75 °C with airflow. It is powered by a single DC input from 9.6 to 60 VDC.
Can the Cisco Catalyst IE-3400H-16T-E be stacked, and is its power redundant?
No. The Cisco Catalyst IE-3400H-16T-E does not support stacking, and it has a single power input rather than dual redundant power supplies. Multiple units are managed as individual switches. Network-layer resiliency is built with Resilient Ethernet Protocol (REP), Media Redundancy Protocol (MRP), Device Level Ring (DLR), or Parallel Redundancy Protocol (PRP) on select ports, so ring topologies rather than stacking or dual power provide redundancy.
What is the difference between the IE-3400H-16T-E and the IE-3400H-16T-A?
The Cisco Catalyst IE-3400H-16T-E and IE-3400H-16T-A are the same IP67 M12 hardware, with 16 Gigabit Ethernet ports, and identical performance, and differ only in license tier. The IE-3400H-16T-E ships with perpetual Network Essentials, which covers Layer 2 switching with inter-VLAN and IPv4 static routing. The IE-3400H-16T-A ships with perpetual Network Advantage, which adds full dynamic routing (OSPF, BGP, RIP, IS-IS, and EIGRP for IPv4 and IPv6), VRF-lite, MACsec-256, and SGT/SGACL group-based segmentation with Cisco TrustSec. The 3,000 IPv4 route scale also requires Network Advantage. Choose the IE-3400H-16T-E when Layer 2 with static routing is sufficient and TrustSec segmentation is not required.
Does the Cisco Catalyst IE-3400H-16T-E support TrustSec segmentation?
No. The Cisco Catalyst IE-3400H-16T-E ships with the Network Essentials license, which provides Layer 2 switching with inter-VLAN and IPv4 static routing but does not include SGT/SGACL Cisco TrustSec segmentation or dynamic routing protocols such as OSPF or BGP. For TrustSec group-based segmentation and dynamic routing on the same hardware, the Network Advantage IE-3400H-16T-A carries those features.
What is the difference between the IE3400 Heavy Duty IE-3400H-16T-E and the IE3400 Rugged Series?
The Cisco Catalyst IE-3400H-16T-E is the IP66/IP67-rated Heavy Duty model, sealed against dust and water with M12 connectors and wall mounting, so it needs no housing cabinet. The DIN-rail IE3400 Rugged Series offers similar switching, routing, and security features but uses RJ45 and SFP ports and is designed to sit in a protected cabinet or enclosure. Choose the Heavy Duty IE-3400H-16T-E when the switch must survive direct exposure to dust and water; choose the Rugged Series for cabinet installs that can use RJ45 and fiber.
Does the IE-3400H-16T-E require a subscription to operate?
No. The Cisco Catalyst IE-3400H-16T-E runs on its perpetual Network Essentials license indefinitely, and no subscription is required for it to operate. Cisco offers optional, separately purchased Cisco Catalyst Center Essentials or Advantage licenses that add discovery, assurance, analytics, and automation; the Catalyst Center Advantage tier also requires the switch to carry Network Advantage. These Catalyst Center licenses are management add-ons, are not mandatory, and do not change the switch's network feature tier.
Is the Cisco Catalyst IE-3400H-16T-E end of life?
No. Cisco has not published a hardware End-of-Sale or End-of-Life notice for the Catalyst IE3400 Heavy Duty Series or the IE-3400H-16T-E. The published end-of-life notices for the series cover specific Cisco IOS XE software releases and the 4GB SD card accessory, not the switch hardware, so the IE-3400H-16T-E remains an actively available product.
What condition is the IE-3400H-16T-E sold in, and what warranty applies?
The Cisco Catalyst IE-3400H-16T-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
