Cisco IE3105 Rugged Managed Switch 18 Port Gigabit 2 Port Combo Uplinks Network Essentials DIN-Rail

SKU CH-H8SB-711Q0

A fanless, DIN-rail managed switch with 18 copper Gigabit ports and 2 combo uplinks, hardened for -40 °C to 75 °C operation

  • Built for extreme environments with fanless operation from -40°C to 75°C
  • 18 Gigabit RJ45 downlink ports plus 2 combo uplinks for flexible connectivity
  • Layer 3 routing with Network Essentials software for secure segmentation
  • Sub-second ring recovery via MRP and REP protocols
  • Hardware-anchored Secure Boot and Image Signing with Trust Anchor Module

Industrial Rugged Switch

The Cisco Catalyst IE3105 is a fanless managed switch built for extreme environments. It operates reliably from -40°C to 75°C with an IP30 rated housing. Designed for industrial automation, transport and substation applications, it mounts on a standard DIN-Rail. The Network Essentials license provides foundational Layer 3 routing and advanced Layer 2 features.

Interface Constraints

The unit delivers 20 Gigabit Ethernet ports in total. Eighteen downlink ports are fixed 10/100/1000Base-T copper RJ45 connections. Two uplink ports are combo interfaces accepting either RJ45 copper or SFP fibre modules. Throughput runs at full line-rate for both Layer 2 and Layer 3 forwarding. The fanless convection cooling eliminates moving parts but limits deployment to convection-friendly enclosures.

Upgrade Path

This switch replaces unmanaged or Layer 2 only switches where deterministic recovery and industrial protocol support are now required. It adds native EtherNet/IP, Modbus and PROFINET integration alongside MRP and REP ring resiliency for sub-second failover. The jump is worth it when PLCs, controllers or IPCs need secure segmentation, IEEE 1588v2 PTP time sync and hardware-anchored Secure Boot. It is not for buyers needing PoE power budgets or port counts beyond 20 Gigabit interfaces.

Questions about this item

How many copper downlink ports does the IE-3105-18T2C-E provide for connecting field devices?

The switch includes 18 Gigabit RJ45 downlink ports for local device connectivity in industrial environments.

What does the 20 Gigabit port total mean for real-world throughput in a factory network?

Full line-rate Layer 2 and Layer 3 forwarding across all 20 ports ensures deterministic performance for time-sensitive automation traffic.

How do the two combo uplink ports work and what media types do they support?

Each combo uplink accepts either an RJ45 copper cable or an SFP fibre module, giving flexible high-speed links to the network core.
