IE-3100-8T4S-E - Cisco IE 3100 Series 8 port GE Copper and 4 GE SFP Switch

Cisco IE-3100-8T4S-E — Industrial Ethernet 3100 Series 8× GE Copper + 4× GE SFP Switch

What it is

IE-3100-8T4S-E is a Cisco Industrial Ethernet 3100 Series rugged managed switch built for industrial and harsh edge networking (manufacturing floors, utilities, transportation, outdoor cabinets).
It offers 8 × Gigabit Ethernet copper access ports plus 4 × Gigabit SFP fiber uplinks, giving you plenty of local device connections with flexible fiber backhaul — all in a hardened chassis designed for extreme temperatures, vibration, electrical noise, and dust.

Why buyers pick IE-3100-8T4S-E (plain English)

8 Ethernet access ports: Plenty of standard 1 Gb copper ports for wired devices like PLCs, HMIs, IP cameras, sensors, and industrial PCs.

4 fiber uplinks: Four SFP slots let you use fiber links for long runs or noisy environments, giving immunity to interference and long distance connectivity.

Industrial-grade reliability: Built to handle temperature swings, shock, vibration, and electrical noise common in field and OT environments.

Managed features: Offers Cisco-style CLI, VLANs, QoS, redundancy protocols, security ACLs, and SNMP/Web management options — great for OT/IT converged deployments.

Where it fits (and when to choose something else)

Perfect for:

• Industrial access closets with many wired endpoints

• Sites needing fiber uplinks for distance or noise immunity

• Smart factories, utilities, transportation, and other OT networks

Choose something else if:

• You need PoE/PoE+ → choose the 8P PoE industrial models

• You want 10G uplinks → look at industrial switches with SFP+

• You don’t need fiber → simpler copper-only IE models cost less

TL;DR

IE-3100-8T4S-E is a rugged Cisco industrial switch with 8× 1G copper access ports and 4× 1G fiber uplinks, built for reliable managed switching at the industrial edge.
