IE-3105-8T2C-E Description
The IE-3105-8T2C-E is a Cisco Catalyst IE3105 Rugged Series industrial switch for small DIN-rail cabinets that need Gigabit copper access and Layer 2 NAT. The switch has eight 10/100/1000 RJ45 ports and two dual-media combo uplinks, with dual DC inputs from 12V to 48V nominal and 28 W power consumption. Layer 2 NAT applies only to the uplink ports, and the switch has no PoE budget.

Product Performance
Key Features
Layer 2 NAT is available on the IE3105 models only, applied to the uplink ports GigabitEthernet1/1 and 1/2, with up to 128 rules.
The RJ45 ports carry data only, so powered endpoints need a separate supply or a PoE model.
Each uplink works as copper or SFP. The SFP side wins by default when both are connected, and the media-type command forces one side.
The switch draws 28 W, about 10 W more than the base IE-3100-8T2C-E, and cabinet power budgets should use that figure.
The IE3105 chassis is 5.08 in. deep against 4.33 in. for the base 8T2C model, which matters in shallow enclosures.
Two DC feeds work as primary and backup over 9.6V to 60V absolute, with the higher-voltage feed carrying the load.
Application Scenarios
A small machine cell reuses a private IPv4 plan, and the switch translates those addresses on its uplinks so the cell can join the plant network.
Cabinets in a pump or utility network that differ in uplink media can run the same switch, with RJ45 copper in one cabinet and SFP fiber in another.
Where eight copper endpoints are enough, the switch fits a shallow DIN-rail space and connects sensors and controllers to the site network.

IE-3105-8T2C-E is the IE3105 variant of IE-3100-8T2C-E: both have eight copper ports and two combo uplinks, but only IE-3105-8T2C-E has the FPGA data path and Layer 2 NAT, at 28 W against 17.7 W and a 5.08 in. chassis depth against 4.33 in. Designs that do not need Layer 2 NAT and have tight cabinet depth can order IE-3100-8T2C-E. Where 18 copper ports are needed with the same IE3105 feature set, order IE-3105-18T2C-E, which forwards 20 Gbps against 10 Gbps. Cabinets that must power endpoints from the switch need IE-3100-8P2C-E with its 240 W PoE budget, though it is not an IE3105 variant and has no Layer 2 NAT.
Ordering Checklist
- Power supply: Order a separate DIN-rail supply such as PWR-IE50W-AC= (50W, AC 100-240V) or PWR-IE50W-AC-L=. The ordering table lists no default power supply, so the switch arrives with nothing to power it.
- SD card: Add SD-IE-1GB= or SD-IE-16GB= if configuration backup is wanted. The card is optional and not shipped by default, so a replacement switch cannot reload its configuration from it unless ordered.
- DIN-rail mounting: Add STK-RACK-DINRAIL= if the switch goes into a 19-inch rack instead of a DIN rail. The rack kit is a separate item, and the data sheet does not say whether DIN-rail or rack hardware ships with the switch.
- Uplink optics: Choose Cisco-listed 100M or 1G SFPs for the two dual-media uplinks, using -40 to +85°C industrial-grade SFPs for utility, rail or marine sites. Each uplink uses either the SFP or the RJ45 side.
- Subscription: Optionally add Catalyst Center Essentials subscription IE3100-DNA-E-L (up to 12 ports) with a -1Y, -3Y, -5Y, -7Y or -10Y term. IE-3105-8T2C-E is covered by the Network Essentials license with no separate license PID, so this is the only license line that can be added.
