IE-3105-18T2C-E is a Layer 2+ industrial switch with Layer 2 Network Address Translation (L2NAT) for industrial control networks. Eighteen Gigabit Ethernet copper access ports connect controllers, human-machine interfaces and other externally powered Ethernet devices. The fanless DIN rail chassis belongs to the Cisco Catalyst IE3100 Rugged Series and ships with Network Essentials. Two fixed Gigabit combo uplinks provide copper or fiber connectivity without a removable uplink card; the access ports do not deliver PoE. IE-3100-18T2C-E omits the FPGA data path present in the advanced model. For hardware selection, address translation is the distinguishing requirement: the advanced industrial variant is not simply a higher subscription tier attached to the same base hardware.
IE-3105-18T2C-E price for new stock is $4,328.10, a 70.9% saving from the Cisco list price of $14,876.98. IE-3105-18T2C-E refurb price is $7,438.49. IE-3105-18T2C-E is in stock and available for next-day dispatch. (terms applied)

20 Gbps forwarding bandwidth defines the traffic-throughput envelope, while 29.76 Mpps forwarding is measured using 64-byte packets. Static routing and inter-VLAN routing provide routed connectivity without a dynamic-routing feature set. IE-3105-18T2C-E carries 4 GB DRAM and 1.5 GB user-accessible flash for its software and configuration storage. The IE-3105 Rugged Series supports 8000 learned MAC addresses and 256 VLANs, bounding address learning and segmentation scale; eight egress queues determine traffic scheduling granularity. STP, RSTP, MSTP and LACP supply loop-control and link-aggregation options. WebUI, the Cisco IOS XE CLI and SNMP support administration, with NETCONF and RESTCONF available for configuration automation. CIP and PROFINET integrate industrial management. 36.7W power consumption is the thermal-load planning figure; source and conductor sizing instead use the maximum-current and inrush requirements for the selected input voltage.

For a control-cabinet consolidation that must retain external fault signaling, two dry-contact alarm inputs and one Form-C relay output provide connection points for the alarm design. Prepare the contact-state requirements and external alarm wiring schedule before placing the switch order.
When preparing a staged spare for an industrial site, an optional SD-IE-16GB= card provides removable storage for transferring files and preparing replacement hardware. The card is not included by default. Specify SD-IE-16GB= on the PO and validate the intended configuration-copy procedure before accepting the spare.
For standardization across utility, railway or marine sites, shielded Ethernet cabling is required for the relevant EMC installation requirements. Marine installations also require a metal enclosure. Align the enclosure and cabling requirements with each site's installation conditions before issuing a common purchase order.
PoE power for connected endpoints
IE-3105-18T2C-E supplies no PoE. IE-3100-8P2C-E adds PoE+ on eight access ports, reducing copper access density from eighteen ports.
Uplinks faster than Gigabit Ethernet
IE-3105-18T2C-E limits uplinks to 1G through fixed combo interfaces. A faster uplink requirement cannot be met by adding a removable uplink card.

IE-3105-18T2C-E uses IE-3105 for the advanced-feature Catalyst IE3105 hardware, 18 for eighteen access ports, T for Gigabit copper, 2C for two Gigabit combo uplinks, and E for Network Essentials. The complete number identifies a fixed industrial switch rather than a removable card or power accessory.
Catalyst IE3100 Rugged switches support WebUI, CLI through local console, SSH or Telnet, SNMP, NETCONF, RESTCONF, CIP tools and PROFINET tools. Cisco Catalyst Center provides centralized management with the optional Essentials add-on license. Local console access uses RJ-45 or micro-USB; select the management path and entitlement before deployment.
Cisco has not announced an end-of-sale date for Catalyst IE3100 Rugged. Software-release and removable-storage lifecycle milestones are separate from the switch hardware lifecycle. A retirement date for either category does not establish a hardware end-of-sale date for IE-3105-18T2C-E or create a replacement hardware PID.
ORM offers IE-3105-18T2C-E new sealed or certified refurbished. Cisco’s platform warranty is a five-year limited hardware warranty. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Every condition includes 30-day returns; terms apply.
IE-3105-18T2C-E includes perpetual Network Essentials; optional Cisco Catalyst Center Essentials has a one-year minimum term. IE3100-DNA-E-M-1Y covers the applicable port-count band. Hardware switching does not require that add-on, so an ORM certified refurbished hardware order does not create a mandatory Catalyst Center subscription purchase.
IE-3105-18T2C-E replaces discontinued IE-2000-16TC-G-N, whose end-of-sale date was July 26, 2024. The predecessor’s last date of support is July 31, 2029; that milestone belongs to the older hardware. Identify the legacy PID on the migration order so the replacement is not confused with another IE2000 configuration.
IE-3105-18T2C-E supports 1G fiber through its fixed combo uplinks; GLC-LX-SM-RGD= is a supported industrial 1000BASE-LX/LH optic for single-mode links to 10 km. The copper and fiber connectors share each uplink. Match GLC-LX-SM-RGD= to the fiber and environmental requirements before adding optical components to the PO.
IE-3105-18T2C-E accepts external DC power through two terminal-block inputs, with 12-48V DC nominal operation. Either input can power the unit; independent sources enable active-standby power continuity. The higher-voltage input supplies the load when both feeds are present. Specify independent upstream circuits when redundant power is required.
IE-3105-18T2C-E supports static routing and inter-VLAN routing with Network Essentials, placing the as-shipped feature set at Layer 2+. A design requiring dynamic routing needs a different feature set and should not treat the E suffix as an upgrade entitlement for unsupported routing functions.
IE-3100-8P2C-E delivers PoE+ to eight access ports, while IE-3105-18T2C-E provides eighteen non-PoE access ports. The powered variant suits orders for endpoints needing Ethernet-delivered power. The higher-density model suits externally powered devices, so confirm both endpoint power requirements and connection count before choosing between them.
IE-3105-18T2C-E includes an FPGA data path, whereas IE-3100-18T2C-E does not. The advanced model also supplies L2NAT for industrial address translation. Choose the advanced hardware when address translation is an explicit requirement; the base model suits orders that do not require that capability.
IE-3105-18T2C-E has eighteen copper access ports where IE-3105-8T2C-E has eight; both provide two Gigabit combo uplinks. The eighteen-port model suits a larger wired endpoint schedule. The eight-port model suits smaller connection counts, so select by the actual copper access requirement rather than the shared uplink arrangement.
No, Catalyst IE3100 Rugged switches are rated to 60°C in sealed cabinets; 75°C requires a blower-equipped cabinet. Vented cabinets have a 70°C operating limit. Cabinet construction belongs in the environmental acceptance criteria rather than being inferred from the switch’s fanless cooling or industrial product designation.
