IE-3400-8P2S-E - Cisco IE 3400 Rugged Series 8 Port Switch

Cisco IE-3400-8P2S-E — Industrial Ethernet 3400 Series Switch (8× PoE+ 1G + 2× 1G SFP)

What it is

IE-3400-8P2S-E is a Cisco Industrial Ethernet 3400 Series rugged managed switch built for industrial edge deployments (factories, utilities, transportation, outdoor cabinets).
It provides 8 × 10/100/1000Base-T PoE+ ports for powered devices plus 2 × 1G SFP uplinks for fiber backhaul — all in an industrial-ready chassis designed to survive heat, vibration, dust, and electrical noise.

Why buyers pick IE-3400-8P2S-E (plain English)

• Industrial-rated reliability
  Built for harsh spaces where normal access switches don’t last.

• PoE+ for edge devices
  Powers cameras, access control, Wi-Fi APs, sensors, and controllers without injectors.

• Fiber uplinks for distance + noise immunity
  SFP uplinks make long runs cleaner and safer in electrically noisy environments.

• Managed features with Cisco familiarity
  VLANs, QoS, redundancy protocols, and Cisco CLI-style operation.

• Clean IT/OT integration
  A strong option for industrial networks that need enterprise management standards.

Access / downlink ports

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

Uplinks

• 2 × 1G SFP fiber uplink ports

PoE

• PoE+ per port (up to 30W each, budget-limited)

• Total PoE budget depends on input power and configuration

Switching / features

• Managed Layer 2 switching (VLANs, QoS, STP/RSTP/MSTP)

• Security options (ACLs, port security)

Management

• Cisco CLI, SNMP, web tools (platform dependent)

Ruggedization

• Industrial temperature tolerance

• Enhanced surge/ESD protection

• DIN-rail / wall mounting options

Where it fits (and when to choose something else)

Perfect for:

• Industrial PoE edge deployments (cameras, APs, access control)

• Harsh cabinets needing PoE + fiber uplinks

• OT environments that still want enterprise-style manageability

Choose something else if:

• You don’t need rugged hardware → campus switches cost less

• You need 10G uplinks → look for industrial models with SFP+

• You need more ports → larger IE-3400 variants

TL;DR

IE-3400-8P2S-E is a rugged Cisco industrial PoE switch:
8×1G PoE+ copper downlinks + 2×1G SFP uplinks — built for harsh environments needing powered edge connectivity and fiber backhaul.
