IE-3100-8P2C-E - Cisco IE 3100 Series 8 port GE PoE Switch

Cisco IE-3100-8P2C-E — Industrial Ethernet 3100 Series 8× GE PoE + 2× Copper Uplink Switch

What it is

IE-3100-8P2C-E is a Cisco Industrial Ethernet 3100 Series ruggedized managed switch designed for harsh edge and industrial environments (factories, utilities, transportation, outdoors).
It provides 8 × Gigabit Ethernet copper access ports with PoE+, plus 2 × Gigabit copper uplinks, giving powered connectivity and uplink flexibility in a hardened chassis built to withstand temperature swings, electrical noise, vibration, and dust.

Why buyers pick IE-3100-8P2C-E (plain English)

PoE+ for field devices: Eight PoE+ ports power wireless APs, IP cameras, VoIP phones, access controllers, sensors, and other powered endpoints without separate injectors.

Copper uplinks: Two 1G copper uplinks make it easy to connect back to aggregation/core switches over standard RJ-45 links.

Industrial-grade reliability: Built for extreme temperatures, electrical interference, and rugged spaces where office switches fail.

Managed features: Supports VLANs, QoS, security ACLs, redundancy protocols, and Cisco CLI-style operations suited to OT/IT teams.

60-second spec box (IE-3100-8P2C-E)

Access / downlink ports

• 8 × 10/100/1000Base-T RJ-45 with PoE+ (802.3at) on all access ports

Uplinks

• 2 × 10/100/1000Base-T RJ-45 (non-PoE) uplink ports

PoE

• PoE+ supported across all 8 access ports

• Total PoE budget depends on the PSU/configuration

Switching / features

• Managed Layer 2 switching

• VLANs, QoS, STP/RSTP/MSTP

• Security ACLs, DHCP options

Management

• Cisco CLI

• SNMP, Web UI (platform dependent)

Ruggedization

• Industrial temperature tolerance

• Enhanced surge/ESD protection

• DIN-rail or wall mounting

Where it fits (and when to choose something else)

Perfect for:

• Industrial sites needing lots of PoE+ on the edge

• Powering cameras, APs, access controllers, and sensors

• Rugged environments where reliability matters most

Choose something else if:

• You need fiber uplinks → consider models with dual SFP

• You need 10G uplinks → industrial switches with SFP+

• You don’t need PoE → non-PoE IE-3100 variants

TL;DR

IE-3100-8P2C-E is a rugged Cisco industrial PoE+ edge switch with 8× powered ports and 2× Gigabit copper uplinks — ideal for powering edge devices and connecting robustly back to the network in harsh environments.
