IE-3100-4T2S-E Description
IE-3100-4T2S-E is a Cisco Catalyst IE3100 Rugged Series Industrial Ethernet switch for compact industrial edge deployments that need fixed Gigabit access ports in a DIN-rail form factor. This Network Essentials model provides 4 x 10/100/1000 RJ45 copper downlink ports and 2 x 1000BASE-X SFP uplink ports, uses dual DC power inputs, is identified as a non-PoE IE3100 variant, and is specified at 14 W power consumption with an 8.928 Mpps forwarding rate for industrial automation, utility, transportation, or hardened access networks where the exact port mix and power profile must match the BOM.

Product Performance
Key Features
IE-3100-4T2S-E fits cabinets that need four Gigabit copper endpoints and two fiber uplink positions without moving to an 8-port or 18-port chassis.
The two uplinks are 1000BASE-X SFP ports rather than combo ports, so the fiber handoff and SFP family should be settled before the order is released.
Cisco does not list a PoE budget for IE-3100-4T2S-E, which keeps this PID separate from the powered IE-3100-4P2S-E and larger PoE IE3100 variants.
Cisco maps this exact product ID to Network Essentials, keeping the E suffix tied to the intended IE3100 software tier during substitution review.
The data sheet lists 12V to 48V nominal input, 9.6V to 60V absolute input, and 14 W power consumption for this non-PoE model.
Cisco documents DIN-rail mounting, alarm I/O, SD card support, Cisco IOS XE, WebUI, Catalyst Center management, and industrial protocol support for the IE3100 family.
Application Scenarios
IE-3100-4T2S-E suits machine-area cabinets where PLCs, HMIs, drives, sensors, or controllers need Gigabit RJ45 access and the design does not assign switch-supplied power.
This model is appropriate when the cabinet needs two SFP-only uplinks for 100/1000 fiber handoff instead of dual-media copper/SFP combo uplinks.
Fits projects standardizing on IE3100 Network Essentials where the site needs a compact four-port access switch rather than the powered 4P2S-E or the 8-port 8T2C-E.

- In an IE-3100-4T2S-E vs IE-3100-4P2S-E comparison, both models keep four copper ports and two SFP uplinks, but IE-3100-4P2S-E adds PoE/PoE+ and a 120 W PoE budget.
- The IE-3100-4T2S-E vs IE-3100-8T2C-E decision is port density and uplink type: IE-3100-4T2S-E has four RJ45 ports with SFP-only uplinks, while IE-3100-8T2C-E has eight RJ45 ports and two combo uplinks.
- For IE-3100-4T2S-E vs IE-3100-8T4S-E comparison work, both are non-PoE SFP-uplink IE3100 models, but IE-3100-8T4S-E doubles the copper port count and increases SFP uplinks to four.
- Buyers deciding which model to choose should lock endpoint power, copper-port count, and SFP-only versus combo uplink requirements before treating these IE3100 Network Essentials PIDs as substitutes.
Selection Guide
1. Keep 4T2S-E for a small data-only cabinet
Choose IE-3100-4T2S-E when the BOM requires four Gigabit copper access ports, two 1GE SFP uplinks, Network Essentials, and no PoE budget.
2. Move to 4P2S-E for powered endpoints
Select IE-3100-4P2S-E when the same four copper access positions must provide PoE/PoE+ power and the order needs the Cisco-listed 120 W PoE budget.
3. Use 8T2C-E for more copper endpoints
Move to IE-3100-8T2C-E when eight data-only RJ45 ports are required and the design accepts two dual-media combo uplinks instead of two SFP-only uplinks.
4. Reserve 8T4S-E for more fiber uplinks
Select IE-3100-8T4S-E when the cabinet needs eight RJ45 ports and four 100/1000 SFP uplinks while staying in the non-PoE IE3100 Network Essentials group.
