Cisco Catalyst IE-3100-4P2S-E 6-Port PoE+ Industrial DIN-Rail Switch with 2x 1G SFP Uplinks, Network Essentials

The Cisco Catalyst IE-3100-4P2S-E provides Power over Ethernet and PoE+ (802.3af and 802.3at) on its 4 copper access ports, delivering up to 30 W per port from a 120 W system PoE budget. 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 120 W budget is shared across all powered ports, so the number of devices depends on each endpoint's draw.

The Cisco Catalyst IE-3100-4P2S-E has two 1G SFP fiber uplink ports. These are 1-Gigabit slots; 10G optics are not supported. For industrial temperature ranges Cisco offers ruggedized SFPs such as GLC-SX-MM-RGD and GLC-LX-SM-RGD. Specific transceiver compatibility should be verified against Cisco's transceiver compatibility matrix for this platform. Transceivers are sold separately.

No. The Cisco Catalyst IE-3100-4P2S-E does not support stacking, and the IE3100 Rugged Series has no stacking technology. Multiple units are managed as individual switches. Redundancy is built at the network layer using Resilient Ethernet Protocol (REP), Media Redundancy Protocol (MRP), Fast MRP, or G.8032 Ethernet Ring Protection, and at the hardware layer using the switch's dual DC power inputs, which allow two independent power feeds.

The Cisco Catalyst IE-3100-4P2S-E operates from -40 °C to +70 °C in a vented cabinet, from -40 °C to +60 °C in a sealed cabinet, and from -40 °C to +75 °C in a blower-equipped cabinet. It is fanless and convection-cooled with no moving parts, mounts on a DIN rail, and is powered by dual DC inputs (12 V to 54 V nominal, 9.6 V to 60 V absolute). Storage temperature is -40 °C to +85 °C and operating altitude is up to 15,000 feet with no derating. It is hardened against vibration, shock, surge, and electrical noise.

The Cisco Catalyst IE-3100-4P2S-E is a Layer 3 switch. With its perpetual Network Essentials license it performs inter-VLAN routing and IPv4 static routing and holds up to 2,000 IPv4 indirect routes, but it does not run dynamic routing protocols such as OSPF, EIGRP, or BGP, and there is no higher network license tier for the IE3100. For full dynamic routing, a different platform is required.

No. The Cisco Catalyst IE-3100-4P2S-E runs on its perpetual Network Essentials license indefinitely, and no subscription is required for it to operate or to keep its switching, static routing, and ring resiliency features. Cisco offers an optional, term-based Cisco Catalyst Center Essentials license that adds discovery, inventory, assurance, automation, and SD-Access Extended Node support. That license is a management add-on, is not mandatory, and does not change the switch's network feature tier.

No. Cisco has not published a hardware End-of-Sale or End-of-Life notice for the Catalyst IE3100 Rugged Series or the IE-3100-4P2S-E. The published end-of-life notices for the series cover specific Cisco IOS XE software releases and the 4GB SD card accessory, not the switch hardware, so the IE-3100-4P2S-E remains an actively available product.

The Cisco Catalyst IE-3100-4P2S-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
