Cisco Catalyst IE-3400-8T2S-E — 8× 1G copper + 2× SFP in a rugged, modular DIN-rail switch (Network Essentials)

What it is: A compact, ruggedized Catalyst IE3400 switch with 8 × 10/100/1000 RJ-45 downlinks and 2 × SFP uplink slots (FE/GE), running IOS-XE (Network Essentials). The modular design lets you add an expansion module to grow ports and optionally deliver PoE/PoE+.

Why buyers pick IE-3400-8T2S-E

• Industrial hardening without the bulk: fanless, DIN-rail, wide –40 to +75 °C operating range.

• Grows with your panel: add an expansion module to scale up to 26 ports and enable PoE/PoE+ (with appropriate PSU).

• Modern IOS-XE features: open APIs, WebUI, Flexible NetFlow, and Cisco security/visibility hooks.

• Right license out of the box: Network Essentials (“-E”) baseline L2/L3 with an upgrade path to Network Advantage.

Modularity / PoE

• 1 × expansion module bay (4/8-port options; variants with PoE/PoE+)

• System PoE budget up to ~480 W when using PoE expansion and suitable power supplies (model-dependent)

Ruggedization

• Operating temp: –40 to +75 °C (fanless)

• Enclosure: IP30, DIN-rail mountable

Power

• Dual redundant DC inputs: 9.6–60 VDC (pluggable field power)

Software / features

• IOS-XE, Network Essentials license; optional upgrade to Network Advantage

• Industrial protocols & timing: PTP (IEEE 1588v2), REP/MRP/DLR ring options; rich QoS, VLANs, ACLs; static routing/OSPF availability per license

• Telemetry/ops: Flexible NetFlow; manage via WebUI or Catalyst Center

Use cases

• Factory cells, utility substations, ITS/wayside cabinets, outdoor warehouses/campuses needing hardened 1G access with a couple of fiber uplinks—plus room to add PoE later.

What to order with it (common adds)

• SFP optics: 1G SX/LX/ZX as distance dictates

• Expansion module: 4/8-port (with or without PoE/PoE+)

• DIN-rail DC supply: sized for load; plan dual feeds for redundancy

TL;DR

IE-3400-8T2S-E is the rugged, DIN-rail Catalyst with 8× 1G copper + 2× SFP, –40…+75 °C, dual 9.6–60 VDC, and a modular bay to scale ports and add PoE when you need it—on familiar IOS-XE with Network Essentials.
