IE-3105-18T2C-E Description
IE-3105-18T2C-E is a Cisco Catalyst IE3105 Rugged Series DIN-rail industrial Ethernet switch for OT access cabinets that need high-density copper connectivity. It provides 18 10/100/1000 RJ45 downlinks, two 1000BASE-T/1000BASE-X dual-media combo uplinks, Network Essentials, an FPGA data path, dual DC inputs, and 36.7W power consumption for compact industrial edge deployments.

Key Features
IE-3105-18T2C-E is the Cisco-listed 18T2C IE3105 SKU with Network Essentials and FPGA data path, so it should not be treated as the matching IE-3100-18T2C-E base model.
The access side uses 18 10/100/1000 RJ45 downlink ports, which keeps the endpoint plan in Gigabit copper rather than PoE, Fast Ethernet, or SFP-only access.
Each uplink position can be planned around 1000BASE-X SFP or 1000BASE-T copper media, and Cisco notes that the SFP side has priority when both media types are active by default.
Cisco’s IE31xx security guide limits Layer 2 NAT support on IE3105 to uplink ports GigabitEthernet1/1 and GigabitEthernet1/2, which makes the uplink role a design check rather than a downlink assumption.
The data sheet places this model in the dual-DC-input group with 12V to 48V nominal input and 9.6V to 60V absolute input, so power-source sizing should follow the industrial enclosure plan.
Cisco describes the IE3100 platform for DIN-rail industrial enclosures with temperature, vibration, shock, surge, and electrical-noise hardening for harsh environments.
Application Scenarios
IE-3105-18T2C-E fits cabinets where many PLCs, HMIs, sensors, drives, cameras, or other Ethernet-enabled industrial devices need 1G RJ45 access from a compact DIN-rail switch.
Use this IE3105 model when the design needs Cisco-documented Layer 2 NAT on the two uplink interfaces to integrate machine networks that reuse private IPv4 addressing.
The SKU works for industrial access refreshes where the BOM needs 18 copper endpoints and the uplink decision may be either rugged SFP fiber or RJ45 copper instead of a fixed SFP-only model.

- In an IE-3105-18T2C-E vs IE-3100-18T2C-E comparison, both SKUs keep 20 total ports, 18 RJ45 downlinks, two combo uplinks, Network Essentials, and 36.7W power consumption; the difference is the IE3105 FPGA data path and IE3105 L2NAT scope.
- The IE-3105-18T2C-E vs IE-3105-8T2C-E difference is copper density: IE-3105-18T2C-E has 18 RJ45 downlinks and 20 total ports, while IE-3105-8T2C-E has eight RJ45 downlinks and 10 total ports.
- For buyers deciding which model to choose, the IE-3105-18T2C-E comparison should confirm whether the project needs the IE3105 enhanced feature set and the 18-downlink footprint in the same line item.
Selection Guide
1. Choose it for IE3105 18-port access
Select IE-3105-18T2C-E when the BOM requires 18 Gigabit copper downlinks, two dual-media uplinks, Network Essentials, and Cisco’s IE3105 enhanced feature boundary.
2. Use IE-3100-18T2C-E for the base 18T2C class
Move to IE-3100-18T2C-E only when the same port layout is needed without the IE3105 FPGA data path and IE3105 L2NAT positioning.
3. Step down to IE-3105-8T2C-E for smaller cabinets
Use IE-3105-8T2C-E when the design still needs the IE3105 class but eight copper downlinks are enough for the enclosure.
4. Confirm the uplink and power accessories separately
Check rugged SFPs, copper uplink preference, industrial DC supply sizing, SD card needs, and DIN-rail installation hardware before the quote is released.

Confirms whether the order needs rugged SFP optics or RJ45 uplink cabling |
|
L2NAT design |
L2NAT planned only on IE3105 uplink ports GigabitEthernet1/1 and GigabitEthernet1/2 |
Keeps NAT assumptions out of downlink-port design |
|
Power design |
Dual DC inputs sized for 12V to 48V nominal and 36.7W consumption |
Prevents enclosure power supplies and wiring from being undersized |
|
Installation environment |
DIN-rail cabinet with industrial temperature, shock, vibration, and grounding practices reviewed |
Reduces staging risk in harsh OT locations |
|
Service accessories |
SD card, rugged SFPs, console cable, and IE power supplies ordered only when required |
Avoids assuming optional items are included with the base switch |
