IE-3100-4P2S-E Description
IE-3100-4P2S-E is a Cisco Catalyst IE3100 Rugged Series Network Essentials switch with four PoE/PoE+ Gigabit copper ports and two SFP-only uplinks. It is used in small industrial cabinets where a limited number of powered endpoints need fiber uplink handoff.
Pick this SKU when four powered ports and a 120 W PoE budget match the site plan. IE-3100-4T2S-E removes PoE, IE-3100-8P2C-E increases powered-port density and changes to combo uplinks, and 4PPoE variants should be used only when higher endpoint power is required.
Before sourcing, verify the PoE budget, 12 to 54 VDC input, PoE software baseline, SFP optics, powered-device class, stock, price, warranty coverage, shipping options, and lead time. Layer23-Switch can help confirm compatibility and shipment details.

Product Performance
Key Features
IE-3100-4P2S-E is the small IE3100 PoE/PoE+ model for cabinets that need four powered Gigabit copper endpoints without moving to an 8-port powered switch.
The two uplinks are 1000BASE-X SFP ports, so the fiber handoff and supported optic choices should be handled as separate BOM items.
Cisco maps the E-suffix PID to Network Essentials, which keeps the order tied to the intended IE3100 license level.
Cisco release notes state that PoE support for IE-3100-4P2S-E begins with Cisco IOS XE 17.15.1, so staging software is part of the powered-port check.
The switch and connected PoE load must stay within the selected DIN-rail power supply wattage, making PSU selection part of the same purchase decision.
Cisco lists DIN-rail mounting, dual DC inputs, alarm I/O, SD-card support, Cisco IOS XE, WebUI, and Catalyst Center management for the IE3100 platform.
Application Scenarios
IE-3100-4P2S-E fits an industrial enclosure where up to four powered Gigabit endpoints need local access and the uplink design is fiber based.
Keep this SKU in the refresh plan when a site is replacing a data-only edge switch and now needs PoE/PoE+ on the same four-copper-port class.
This model works for OT access cells that need two SFP uplinks and do not need combo copper/SFP uplinks or more than four powered access ports.

- In an IE-3100-4P2S-E vs IE-3100-4T2S-E comparison, the port layout stays at four copper downlinks and two SFP uplinks, but IE-3100-4P2S-E adds PoE/PoE+ and a 120 W power budget.
- The IE-3100-4P2S-E vs IE-3100-3P1U2S-E difference is endpoint power class: IE-3100-4P2S-E gives four PoE/PoE+ ports, while IE-3100-3P1U2S-E reserves one downlink for 4PPoE.
- For IE-3100-4P2S-E vs IE-3100-8P2C-E comparison work, the main split is density and uplink type because the 8P2C-E model has eight powered downlinks and two combo uplinks.
- Buyers deciding which model to choose should confirm powered endpoint count, 4PPoE need, SFP-only versus combo uplinks, and the power-supply budget before treating these IE3100 Network Essentials PIDs as interchangeable.
Selection Guide
1. Choose the four-port PoE SFP-uplink profile
Choose IE-3100-4P2S-E when the order needs four Gigabit PoE/PoE+ copper downlinks, two SFP uplinks, and the Cisco-listed 120 W PoE budget.
2. Keep 4T2S-E only for data-only endpoints
Move to IE-3100-4T2S-E when the same compact 4 copper plus 2 SFP layout is required without switch-supplied endpoint power.
3. Select 3P1U2S-E for one 4PPoE port
Use IE-3100-3P1U2S-E when the cabinet needs one 4PPoE high-power downlink; IE-3100-4P2S-E is documented for PoE/PoE+ on four downlinks.
4. Verify software and external power before substitution
Confirm Cisco IOS XE 17.15.1 or later and size the DC power supply against the switch load plus planned PoE draw because both items control whether the powered-port design is usable.
