IE-3400-8T2S-A - Cisco IE3400 Rugged Series 10 Port Network Advantage Switch

Cisco IE-3400-8T2S-A — Industrial Ethernet 3400 Series Switch (8× 1G Copper + 2× 1G SFP)

What it is

IE-3400-8T2S-A is a Cisco Industrial Ethernet 3400 Series rugged managed switch designed for industrial edge networks (manufacturing, utilities, transportation, outdoor cabinets).
It provides 8 × 10/100/1000Base-T RJ-45 ports for standard wired devices plus 2 × 1G SFP uplinks for fiber backhaul — all in an industrial-ready chassis built to handle harsh conditions.

Why buyers pick IE-3400-8T2S-A (plain English)

• Industrial-grade reliability
  Built for cabinets, plant floors, and outdoor enclosures where office switches won’t survive.

• Perfect for non-PoE endpoints
  Great for PLCs, controllers, industrial PCs, and sensors that don’t need power from the switch.

• Fiber uplinks for distance + noise immunity
  1G SFP uplinks are ideal for long runs and electrically noisy environments.

• Cisco-managed features
  VLANs, QoS, redundancy protocols, and familiar Cisco CLI-style operation.

Where it fits (and when to choose something else)

Perfect for:

• Industrial networks needing 8 copper ports + fiber uplink

• Harsh environments where reliability matters

• OT edge switching with enterprise manageability

Choose something else if:

• You need powered ports → choose an 8P2S PoE+ variant

• You need 10G uplinks → pick an industrial model with SFP+

• You need more ports → larger IE-3400 variants

TL;DR

IE-3400-8T2S-A is a rugged Cisco industrial switch:
8×1G copper downlinks + 2×1G SFP uplinks — ideal for harsh environments where you need managed switching and fiber backhaul without PoE.
