IE-3505-8P3S-E Description
IE-3505-8P3S-E is a Cisco IE3505 Rugged Series advanced modular industrial Ethernet switch for industrial access deployments that need Network Essentials switching, local PoE delivery, and fiber uplink handoff in a compact DC-powered platform. The exact 8P3S-E model provides eight 10/100/1000 PoE/PoE+ copper ports, three 100/1000 SFP uplink ports, a 240 W base PoE budget, and up to 480 W total PoE budget when used with an IE3500 expansion module, making it a fit for rugged cabinets that must connect and power field devices while keeping uplink connectivity on SFP interfaces.

Product Performance
Key Features
Cisco places IE-3505-8P3S-E in the IE3505 advanced modular group, so it should be treated as the IE3505 8P3S PoE order line rather than a standard IE3500 8P3S substitute.
The E suffix maps this exact PID to Network Essentials, while the matching IE-3505-8P3S-A line changes the software tier to Network Advantage on the same port profile.
The three uplinks are documented as fiber 100/1000 SFP ports, keeping the fiber BOM on GE SFP optics instead of the 1G/10G SFP+ optics used by 3X or U3X variants.
The IE3505 8P3S profile keeps a 240 W base-switch PoE value and raises the expansion-inclusive budget to 480 W, separating it from the IE-3500-8P3S-E 360 W system limit.
Cisco marks PRP, HSR, DLR, and related redundancy functions as supported on IE3505 variants, making the 3505 base relevant when those industrial redundancy features are part of the design review.
The switch uses 12 to 54 VDC input with 11.0A maximum current, and Cisco notes that the PoE budget must be configured to match the installed power supplies and connected endpoint load.
Application Scenarios
IE-3505-8P3S-E fits a DIN-rail control cabinet where cameras, panels, access points, or other industrial endpoints need PoE/PoE+ Gigabit copper and the upstream plant network stays on 100/1000 SFP fiber.
Fits designs that specifically call for an IE3505 advanced modular switch where the architecture review includes Cisco-supported industrial redundancy functions rather than a standard IE3500 8P3S base.
This order line suits sites that want Network Essentials by default while reserving the expansion module, power supply, GE optic, and Network Advantage upgrade decisions as separate BOM items.

- In an IE-3505-8P3S-E vs IE-3505-8P3S-A comparison, the hardware, PoE budget, and GE SFP uplink plan match; the confirmed difference is Network Essentials versus Network Advantage.
- The IE-3505-8P3S-E vs IE-3500-8P3S-E difference is the IE3505 advanced modular base and PoE headroom, because the 3505 line lists 480 W total PoE budget with expansion module while the standard 3500 8P3S line lists 360 W.
- For IE-3505-8P3S-E vs IE-3500-8U3X-E comparison work, the key split is port capability: IE-3505-8P3S-E stays on PoE/PoE+ and GE SFP uplinks, while IE-3500-8U3X-E adds 4PPoE and 10G/1G SFP+ uplinks.
- Buyers deciding which model to choose should first verify IE3505 versus IE3500 platform need, then check license tier, powered endpoint class, total PoE budget, and SFP speed class.
Selection Guide
1. Choose it for IE3505 Essentials PoE access
Choose IE-3505-8P3S-E when the BOM requires an IE3505 advanced modular base with Network Essentials, 8 Gigabit PoE/PoE+ copper ports, and 3 GE SFP uplinks.
2. Change only the suffix for Advantage
Move to IE-3505-8P3S-A when the same IE3505 8P3S hardware must be ordered with Network Advantage instead of Network Essentials.
3. Use the standard IE3500 line only when its PoE limit fits
Select IE-3500-8P3S-E only when the project does not require the IE3505 variant and the 360 W expansion-inclusive PoE budget is enough for the endpoint plan.
4. Route 4PPoE or 10G uplinks elsewhere
Use IE-3500-8U3X-E when powered endpoints need 4PPoE or when the upstream design requires the 1G/10G SFP+ uplink class instead of GE SFP.
