IE-3100-4T2S-E is a fanless industrial Layer 2+ switch with four Gigabit copper access ports, two fixed Gigabit SFP uplinks, and Network Essentials. The DIN rail chassis belongs to the Catalyst IE3100 Rugged family and connects locally powered equipment rather than delivering endpoint power over Ethernet. Unlike IE-3100-4P2S-E, this configuration has no PoE+ output. Its fixed interfaces suit an industrial enclosure whose access connections and uplink requirements are already defined, without a removable uplink-card dependency. The Cisco Catalyst IE3100 Rugged Series serves industrial Ethernet applications including automation and transportation. Specify this configuration around the installed equipment's copper connections, the approved fiber topology, and the available cabinet power arrangement.
IE-3100-4T2S-E price for new stock is $1,850.10, a 26.9% saving from the Cisco list price of $2,531.91. IE-3100-4T2S-E refurb price is $1,976.73. IE-3100-4T2S-E is in stock and available for next-day dispatch. (terms applied)

8.928 Mpps forwarding is measured with 64-byte packets, while 6 Gbps forwarding bandwidth provides the published traffic rating. Static routing and inter-VLAN routing permit manually specified paths; this configuration does not provide dynamic routing. STP, RSTP, MSTP, and LACP support Ethernet topology control, while REP and MRP support industrial ring arrangements. IE-3100-4T2S-E carries 4 GB DRAM and 1.5 GB user-accessible flash. An 8000-entry unicast MAC table and 256 VLANs define address-learning and segmentation limits that should be checked against the intended configuration. WebUI and command-line access provide interactive administration, with NETCONF and RESTCONF available for automation. Keep management access requirements separate from the physical uplink plan, and validate the intended configuration before staging multiple units. L2NAT is not supported on this model.
IE-3100-4T2S-E is available new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition, with firmware verified and configuration wiped to factory default. Specify the condition, quantity, and accessory PIDs on the purchase order. ORM provides up to a three-year extended warranty for new units, up to one year for certified refurbished units, and 30-day returns in every condition, with terms applying; Cisco's separate limited hardware warranty is five years. Enterprise and volume orders can use PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock/RMA coverage across the UK, EU, US, and MEA.

When retiring discontinued IE-2000-4TS-G-L units, IE-3100-4T2S-E is a replacement. The former model ended sale on July 26, 2024. Before issuing the purchase order, audit existing uplink media, saved configurations, and endpoint connections rather than assuming the replacement preserves every installation detail.
When procurement needs a repeatable industrial spare build across sites, SD-IE-16GB= provides optional removable storage for transferring files and staging replacements. Keep the storage line item separate from the switch quantity, and establish which locations need a card before finalizing the purchase order.
When a cabinet rollout must report local faults to external equipment, the switch offers two dry-contact alarm inputs and one Form-C relay output. Define which power, port, or environmental conditions should activate the contacts, and specify the external alarm connections before issuing the purchase order.
Power delivery to connected endpoints
IE-3100-4T2S-E has no powered Ethernet ports. IE-3100-4P2S-E adds four PoE+ downlinks while retaining two Gigabit SFP uplinks; size endpoint load and external power together.
Four dedicated fiber uplinks
IE-3100-4T2S-E offers two dedicated SFP uplinks. IE-3100-8T4S-E provides four Gigabit SFP uplinks, but also increases copper access capacity from four ports to eight.
Layer 2 network address translation
IE-3100-4T2S-E does not provide L2NAT. IE-3105-8T2C-E supports L2NAT and changes the configuration to eight Gigabit copper access ports with two Gigabit combo uplinks.

IE-3100-4T2S-E identifies a Catalyst IE3100 configuration: IE-3100 is the series prefix, 4T denotes four Gigabit copper access ports, 2S denotes two Gigabit SFP uplinks, and E denotes Network Essentials. The complete part number distinguishes this data-only configuration from powered models in the same family.
Catalyst IE3100 Rugged supports WebUI, CLI over console, SSH or Telnet, Cisco Catalyst Center, SNMP, NETCONF, RESTCONF, CIP tools, and PROFINET tools including STEP 7 and TIA Portal. Local console connections use RJ-45 RS-232 or USB micro-Type B; establish the administration method before commissioning.
Cisco has not announced an end-of-sale date for Catalyst IE3100 Rugged. IE-3100-4T2S-E has no announced hardware replacement or last-support milestone. Lifecycle dates for individual Cisco IOS XE releases or optional storage accessories are separate from the chassis; evaluate those components independently when specifying software and spares.
IE-3100-4T2S-E is offered new sealed or certified refurbished; Cisco's five-year limited hardware warranty is separate from ORM coverage. ORM provides up to a three-year extended warranty on new units and up to one year on certified refurbished units. Every condition has 30-day returns, with terms applying.
IE-3100-4T2S-E includes perpetual Network Essentials without a mandatory management subscription. Optional Cisco Catalyst Center Essentials starts with the one-year IE3100-DNA-E-L-1Y license; three-, five-, seven-, and ten-year terms are also available. Select a management term separately from the included network license when preparing the purchase order.
IE-3100-4T2S-E replaces IE-2000-4T-B, IE-2000-4T-G-B, IE-2000-4T-G-L, IE-2000-4T-L, IE-2000-4TS-B, IE-2000-4TS-G-B, IE-2000-4TS-G-L, IE-2000-4TS-L, IE-2000U-4S-G, IE-2000U-4T-G, and IE-2000U-4TS-G. These discontinued models ended sale on July 26, 2024, with their last support date on July 31, 2029. Audit access speed, uplink media, and configuration requirements before replacing an installed unit.
IE-3100-4P2S-E adds four PoE+ access ports, whereas IE-3100-4T2S-E provides data-only copper connections. Both retain two Gigabit SFP uplinks. Choose the powered model when endpoint power must travel over Ethernet; choose the non-PoE model when connected equipment already receives power through a separate supply.
IE-3100-8T4S-E provides four Gigabit SFP uplinks compared with two on IE-3100-4T2S-E. The difference matters when an industrial cabinet needs additional independent fiber connections. Specify the smaller model for two uplinks, or the four-uplink model when the approved topology requires that additional connectivity.
IE-3100-18T2C-E provides eighteen Gigabit copper access ports, compared with four on IE-3100-4T2S-E. Count the endpoints assigned to each enclosure before selecting chassis quantities. The four-port model suits smaller connection groups; the eighteen-port model suits a larger group requiring more copper access connections.
IE-3100-4T2S-E accepts one or two external DC feeds and provides active-standby power redundancy. The higher-voltage input supplies the load when both feeds are present. Use separate independent upstream sources rather than a shared feed; compatible external supply options include PWR-IE50W-AC= for an appropriately sized installation.
IE-3100-4T2S-E supports inter-VLAN routing and static routing under Network Essentials, giving it Layer 2+ routing capability. Plan manually maintained routes for this configuration. If the network design requires dynamic routing, validate that requirement against the intended replacement configuration before committing to hardware quantities.
Catalyst IE3100 Rugged supports GLC-SX-MM-RGD= for industrial-temperature 1000BASE-SX multimode fiber connections. Match the optic to the installed cable, remote endpoint, and required reach before ordering. GLC-SX-MM-RGD= supports a maximum distance of 550 m and digital optical monitoring, so include the exact accessory PID in the purchase order.
