IE-3105-8T2C-E Description
IE-3105-8T2C-E is a Cisco Catalyst IE3100 Rugged Series Industrial Ethernet switch for industrial edge networks that need a compact DIN-rail Layer 2 access switch with confirmed copper access and dual-media uplink capacity. This non-PoE Network Essentials model provides eight 10/100/1000 RJ45 ports and two Gigabit Ethernet combo uplink ports that can operate as 1000BASE-T or 1000BASE-X links, with dual DC power inputs, 12V to 48V nominal input range, 28 W power consumption, and IE3105 Layer 2 NAT support for industrial automation, utility, transportation, or hardened campus edge deployments where the exact IE-3105-8T2C-E PID must match Cisco documented hardware scope.

Product Performance
Key Features
The SKU carries the IE3105 distinction that Cisco uses for Layer 2 NAT support, which is the main reason to quote it instead of the visually similar base 8T2C model.
Cisco lists eight 10/100/1000 RJ45 access ports and no PoE budget, so cameras, access points, phones, or sensors that need switch power require a different line item.
Each uplink position can be sourced around RJ45 copper or SFP fiber, so optics and cabling should be selected deliberately rather than assumed from the switch PID.
The model table assigns Network Essentials to IE-3105-8T2C-E, keeping the hardware order separate from optional Cisco Catalyst Center subscription planning.
The Cisco power table gives this IE3105 model a 28 W consumption value, so a cabinet power worksheet should not reuse the lower IE-3100-8T2C-E figure.
Dual DC inputs, alarm I/O, optional SD storage, DIN-rail mounting, and the documented temperature ranges all affect what must ship with the switch for an OT cabinet build.
Application Scenarios
IE-3105-8T2C-E belongs in small machine cells where eight Gigabit copper endpoints are enough and the network design needs Cisco’s IE3105 Layer 2 NAT capability.
Fits sites where the uplink handoff may be RJ45 copper in one cabinet and SFP fiber in another, because both positions are documented as combo ports.
The switch suits an IE3105 refresh where the project wants the IE3105 feature class but would waste cabinet space or budget by stepping up to an 18-port access model.

- In an IE-3105-8T2C-E vs IE-3100-8T2C-E comparison, both models share eight RJ45 ports and two combo uplinks, but IE-3105-8T2C-E is the IE3105 variant with Layer 2 NAT support.
- The IE-3105-8T2C-E vs IE-3105-18T2C-E difference is access density: IE-3105-8T2C-E has 8 copper ports, while IE-3105-18T2C-E raises the same IE3105 family choice to 18 copper ports.
- For IE-3105-8T2C-E vs IE-3100-8P2C-E comparison work, the main split is feature scope versus endpoint power because IE-3100-8P2C-E adds PoE/PoE+ and a 240 W PoE budget but is not an IE3105 variant.
- Buyers deciding which model to choose should lock the Layer 2 NAT requirement, copper endpoint count, PoE need, and cabinet depth before treating these 10-port IE3100-family PIDs as interchangeable.
Selection Guide
1. Anchor the order on the IE3105 requirement
Choose IE-3105-8T2C-E when Layer 2 NAT support is part of the design and the port count stays at eight copper access ports plus two combo uplinks.
2. Use the base 8T2C only after removing L2NAT
Move to IE-3100-8T2C-E only if the same physical layout is acceptable and the IE3105 Layer 2 NAT distinction is not required.
3. Scale up inside IE3105 for endpoint count
Select IE-3105-18T2C-E when the feature family is correct but the cabinet needs 18 copper access ports rather than the eight on this SKU.
4. Separate switch power from endpoint power
Verify the 28 W switch draw and the absence of a PoE budget before substitution because endpoint power requirements change the correct SKU.
