Overview
The Cisco Catalyst IE3400 Rugged Series is the security-focused member of Cisco's rugged industrial line: compact, fanless, modular DIN-rail switches that expand from a 10-port base to as many as 26 ports and are hardened for vibration, shock, surge, and electrical noise. The IE-3400-8T2S-E is the 8-port, data-only configuration with two 1G SFP uplinks 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-3400-8T2S-A adds full dynamic routing and SGT/SGACL Cisco TrustSec segmentation for deployments that need Zero-Trust OT security. It also runs IOx edge applications and supports Cisco Cyber Vision and Secure Equipment Access, and because the series has no stacking, resiliency comes from REP, MRP, and DLR ring topologies and dual redundant DC power inputs.
Technical Details
The Cisco Catalyst IE-3400-8T2S-E is a Layer 2+ managed, fanless DIN-rail industrial switch with 8 Gigabit Ethernet copper data ports and two 1G SFP uplinks, running Cisco IOS XE with the perpetual Network Essentials license. It forwards at line rate on all ports for all packet sizes, holds up to 16,000 MAC addresses, and is a modular platform that expands from its 10-port base to up to 26 ports with expansion modules. It carries no Power over Ethernet, so all eight access ports are data-only. 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 +70 °C in a vented enclosure, and it is fanless with dual redundant DC power inputs. It is used for secure wired connectivity of industrial devices such as PLCs, HMIs, drives, cameras, and sensors in factory-floor, utility, and transportation networks.
Best For
The IE-3400-8T2S-E suits factory-floor, utility, and transportation networks that connect non-powered industrial devices such as PLCs, HMIs, drives, and sensors over Gigabit Ethernet, with two 1G SFP uplinks for aggregation. Its fanless DIN-rail chassis, -40 °C to +70 °C range, dual redundant DC inputs, and modular expansion fit unconditioned enclosures that may need more ports later. The Network Essentials license fits Layer 2 and static-routed segments; sites needing TrustSec segmentation or dynamic routing should order the Network Advantage IE-3400-8T2S-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-3400-8T2S-A rather than this Network Essentials model
- you need 10G uplinks, since these base models have 1G SFP uplinks (the IE3300-8T2X and IE3300-8U2X provide 10G SFP+ uplinks)
- you need to power devices such as IP cameras or wireless access points, since this is a data-only switch with no Power over Ethernet
- you need more than 26 ports, since that is the maximum this modular platform reaches with expansion modules

FAQ
Does the Cisco Catalyst IE-3400-8T2S-E support PoE?
No. The Cisco Catalyst IE-3400-8T2S-E is a data-only switch, and its eight copper access ports carry no Power over Ethernet. It cannot power devices such as IP cameras, wireless access points, or IP phones. For Power over Ethernet in the same series, Cisco offers the IE-3400-8P2S models, which provide PoE and PoE+ from a 240 W budget that expands to 480 W with a PoE expansion module.
What transceivers do the uplinks on the IE-3400-8T2S-E use?
The Cisco Catalyst IE-3400-8T2S-E has two 1G SFP uplink ports. These are 1-Gigabit slots and do not accept 10G SFP+ optics. For industrial temperature ranges Cisco offers ruggedized (RGD) SFP optics; using non-industrial optics derates the switch's operating temperature. Specific transceiver compatibility should be verified against Cisco's transceiver compatibility matrix for this platform. Transceivers are sold separately.
Can the Cisco Catalyst IE-3400-8T2S-E be stacked?
No. The Cisco Catalyst IE-3400-8T2S-E does not support stacking, and the IE3400 Rugged Series has no stacking technology. Multiple units are managed as individual switches. Redundancy is built at the network layer using Resilient Ethernet Protocol (REP), Media Redundancy Protocol (MRP), Device Level Ring (DLR), or Parallel Redundancy Protocol (PRP) on select base ports, and at the hardware layer using the switch's dual redundant DC power inputs.
What are the operating temperature and environmental ratings of the IE-3400-8T2S-E?
The Cisco Catalyst IE-3400-8T2S-E operates from -40 °C to +70 °C in a vented enclosure, from -40 °C to +60 °C in a sealed enclosure, and from -40 °C to +75 °C in a blower-equipped enclosure. It is fanless and convection-cooled with no moving parts, mounts on a DIN rail, and is powered by dual redundant DC inputs (9.6 to 60 VDC). Storage temperature is -40 °C to +85 °C and operating altitude is up to 15,000 feet. It is hardened against vibration, shock, surge, and electrical noise.
What is the difference between the IE-3400-8T2S-E and the IE-3400-8T2S-A?
The Cisco Catalyst IE-3400-8T2S-E and IE-3400-8T2S-A are the same hardware, with eight copper access ports, two 1G SFP uplinks, and identical performance, and differ only in license tier. The IE-3400-8T2S-E ships with perpetual Network Essentials, which covers Layer 2 switching with inter-VLAN and IPv4 static routing. The IE-3400-8T2S-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 indirect-route capacity is available on both the Network Essentials and Network Advantage tiers; Network Advantage is required to populate those routes using dynamic routing protocols rather than static routes. Choose the IE-3400-8T2S-E when Layer 2 with static routing is sufficient and TrustSec segmentation is not required.
Does the Cisco Catalyst IE-3400-8T2S-E support TrustSec segmentation?
No. The Cisco Catalyst IE-3400-8T2S-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-3400-8T2S-A carries those features.
Does the IE-3400-8T2S-E require a subscription to operate?
No. The Cisco Catalyst IE-3400-8T2S-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-3400-8T2S-E end of life?
No. Cisco has not published a hardware End-of-Sale or End-of-Life notice for the Catalyst IE3400 Rugged Series or the IE-3400-8T2S-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-3400-8T2S-E remains an actively available product.
What condition is the IE-3400-8T2S-E sold in, and what warranty applies?
The Cisco Catalyst IE-3400-8T2S-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
