Cisco IE3500 IE-3500-8P3S-E 8-Port PoE+ Industrial DIN-Rail Switch with 3x 1G SFP Uplinks, Network Essentials
- Switch, L3, Managed, 8 × 10/100/1000 (PoE/PoE+) + 3 × 1G SFP uplinks, IP30 rugged, fanless, DIN-rail, modular expansion
Overview
The Cisco IE3500 Rugged Series is Cisco's newest and highest-scale rugged industrial switch line: compact, fanless, modular DIN-rail switches that expand from an 11-port base to up to 27 ports and are built for machine vision, AI-driven analysis, and large-scale OT networks. The IE-3500-8P3S-E is the 8-port PoE+ configuration with three 1G SFP uplinks and a 240 W PoE+ budget at the Network Essentials tier. Both tiers of the IE3500 are Layer 3 and route with OSPF, OSPFv3, RIP, and policy-based routing at the Network Essentials tier. The otherwise-identical Network Advantage IE-3500-8P3S-A adds BGP, IS-IS, and EIGRP, SGT/SGACL Cisco TrustSec segmentation, and SD-Access Fabric Edge for larger or micro-segmented networks. Because these IE-3500 models do not stack, resiliency comes from REP and MRP ring topologies and dual redundant DC power inputs.
Technical Details
The Cisco IE3500 IE-3500-8P3S-E is a Layer 3 managed, fanless DIN-rail industrial switch with 8 PoE and PoE+ Gigabit Ethernet copper ports and three 1G SFP uplinks, running Cisco IOS XE with the perpetual Network Essentials license. It forwards at line rate on all ports, holds up to 24,000 MAC addresses and 7,000 IPv4 routes, and is a modular platform that expands from its 11-port base to up to 27 ports with expansion modules. It is the first Cisco industrial switch with IEEE 802.1Qbu/802.3br TSN frame-preemption. It provides PoE and PoE+ (802.3af/802.3at) on its eight copper access ports from a 240 W base budget, expandable to 360 W with a PoE expansion module, delivering up to 30 W per port. It is a Layer 3 switch with OSPF, OSPFv3, RIP, policy-based routing, and static routing; advanced protocols such as BGP, EIGRP, and IS-IS and Cisco TrustSec segmentation require the Network Advantage tier. Operating temperature is -40 °C to +70 °C in a vented enclosure, and it is fanless with dual redundant DC power inputs. It is used for secure, high-bandwidth wired connectivity of industrial devices such as PLCs, HMIs, drives, machine-vision cameras, and sensors.
Best For
The IE-3500-8P3S-E suits high-bandwidth industrial networks that need to power endpoints such as ruggedized IP cameras, PTZ cameras, wireless access points, and IP phones over Gigabit Ethernet, with a 240 W budget and three 1G SFP uplinks for aggregation. Its fanless DIN-rail chassis, -40 °C to +70 °C range, dual redundant DC inputs, TSN frame-preemption, and modular expansion fit demanding OT networks. A 240 W budget is suitable for mixed deployments of these powered devices; actual device counts depend on each endpoint's draw. The Network Essentials license fits OSPF/RIP-routed segments; sites needing BGP/EIGRP, TrustSec segmentation, or SD-Access fabric should order the Network Advantage IE-3500-8P3S-A instead.
Not suitable if:
- you need BGP, EIGRP, or IS-IS routing, Cisco TrustSec segmentation, or SD-Access fabric edge, since those require the Network Advantage IE-3500-8P3S-A rather than this Network Essentials model
- you need 10G uplinks, since this model has 1G SFP uplinks (the IE-3500-8U3X models provide 10G SFP+ uplinks)
- you need 90 W per port for high-draw endpoints, since this model delivers up to 30 W PoE+ (the UPOE IE-3500-8U3X models provide 802.3bt 4PPoE)
- you need HSR or PRP lossless redundancy, since those are supported on the IE3505 variants rather than the IE-3500 models

FAQ
How much PoE does the Cisco IE3500 IE-3500-8P3S-E provide?
The Cisco IE3500 IE-3500-8P3S-E provides PoE and PoE+ (802.3af and 802.3at) on its eight copper access ports, up to 30 W per port, from a 240 W base budget that expands to 360 W with a PoE expansion module. It supports Perpetual PoE, which keeps powering endpoints through a switch reload, and Fast PoE, which delivers power before the operating system finishes booting. The budget is shared across all powered ports, so device count depends on each endpoint's draw.
What transceivers do the uplinks on the IE-3500-8P3S-E use?
The Cisco IE3500 IE-3500-8P3S-E has three 1G SFP uplink ports; these are 1-Gigabit slots and do not accept 10G SFP+ optics. For industrial temperature ranges Cisco offers ruggedized (RGD) 1G SFP and 100M FE SFP optics; using non-industrial optics derates the switch's operating temperature. Specific transceiver compatibility should be verified against Cisco's transceiver compatibility matrix for this platform. Transceivers are sold separately.
Can the Cisco IE3500 IE-3500-8P3S-E be stacked?
No. The Cisco IE3500 IE-3500-8P3S-E does not support stacking. Multiple units are managed as individual switches. Network-layer resiliency is built with Resilient Ethernet Protocol (REP) and Media Redundancy Protocol (MRP) ring topologies, and hardware redundancy comes from dual redundant DC power inputs. The HSR and PRP lossless-redundancy protocols are available on the separate IE3505 variants, not on the IE-3500 models.
What are the operating temperature and environmental ratings of the IE-3500-8P3S-E?
The Cisco IE3500 IE-3500-8P3S-E operates from -40 °C to +70 °C in a vented enclosure, from -40 °C to +60 °C in a sealed enclosure, and from -40 °C to +75 °C in a blower-equipped enclosure. It is fanless and convection-cooled with no moving parts, mounts on a DIN rail, and is powered by dual redundant DC inputs (9.6 to 60 VDC; 48 VDC for PoE and 54 VDC for PoE+). It is hardened against vibration, shock, surge, and electrical noise.
What is the difference between the IE-3500-8P3S-E and the IE-3500-8P3S-A?
The Cisco IE3500 IE-3500-8P3S-E and IE-3500-8P3S-A are the same hardware, with eight copper access ports, three 1G SFP uplinks, and identical performance, and differ only in license tier. Both are Layer 3 switches that route with OSPF, OSPFv3, RIP, and policy-based routing. The IE-3500-8P3S-E ships with perpetual Network Essentials. The IE-3500-8P3S-A ships with perpetual Network Advantage, which adds BGP, IS-IS, EIGRP, and HSRP routing, VRF-lite, SGT/SGACL Cisco TrustSec segmentation, MACsec-256, and SD-Access Fabric Edge. Choose the IE-3500-8P3S-E when OSPF or RIP routing is sufficient and TrustSec segmentation and SD-Access fabric are not required.
Is the Cisco IE3500 IE-3500-8P3S-E a Layer 3 switch?
Yes. Unlike the IE3300 and IE3400 Essentials tiers, the Cisco IE3500 IE-3500-8P3S-E is a Layer 3 switch at the Network Essentials tier: it runs OSPF, OSPFv3, RIP, and policy-based routing along with inter-VLAN and static routing, and holds up to 7,000 IPv4 routes. Advanced protocols such as BGP, IS-IS, and EIGRP, Cisco TrustSec segmentation, and SD-Access fabric edge require the Network Advantage IE-3500-8P3S-A.
Does the IE-3500-8P3S-E require a subscription to operate?
No. The Cisco IE3500 IE-3500-8P3S-E runs on its perpetual Network Essentials license indefinitely, and no subscription is required to operate. The switch runs on a perpetual Network Essentials license. Cisco Cyber Vision and Secure Equipment Access licensing is not included as part of the Network Essentials tier. Optional Cisco Catalyst Center licenses add discovery, assurance, and automation; the Catalyst Center Advantage tier also requires the switch to carry Network Advantage. These are management add-ons and do not change the switch's network feature tier.
Is the Cisco IE3500 IE-3500-8P3S-E end of life?
No. The Cisco IE3500 Rugged Series is a newly introduced product, and Cisco has published no End-of-Sale or End-of-Life notice for the series or the IE-3500-8P3S-E. It is a current-generation switch running Cisco IOS XE and carries a five-year limited hardware warranty from Cisco.
What condition is the IE-3500-8P3S-E sold in, and what warranty applies?
The Cisco IE3500 IE-3500-8P3S-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
