IE-4000-4TC4G-E is a managed industrial Layer 2+ switch with four Fast Ethernet combo access ports and four fixed Gigabit combo uplinks. Each connection offers an RJ-45 copper interface or an SFP fiber interface; the paired interfaces do not operate simultaneously. The DIN Rail form factor places this non-PoE model in industrial control cabinets rather than a full-width equipment rack. Cisco Industrial Ethernet 4000 Series switching serves manufacturing, energy, and transportation networks requiring hardened connectivity for independently powered equipment. LAN Base is the included software tier, rather than an IP Services configuration. The discontinued IE-4000-8T4G-E carries eight dedicated Fast Ethernet copper access ports instead of four combo access ports.
IE-4000-4TC4G-E price for new stock is $894.60, a 79.8% saving from the Cisco list price of $4,423.00. IE-4000-4TC4G-E refurb price is $792.73. IE-4000-4TC4G-E is in stock and available for next-day dispatch. (terms applied)

Line-rate forwarding across all ports and packet sizes maintains forwarding performance across different frame lengths. IPv4 static routing provides the included routed functionality; dynamic routing requires an additional entitlement. Cisco IE 4000 supports STP/RSTP/MSTP and LACP for topology control and link aggregation, while REP supports industrial ring configurations. IGMP snooping controls multicast delivery, and ingress policing with egress queueing provides traffic-handling controls. IE-4000-4TC4G-E carries 1 GB DRAM for system operation and 128 MB onboard flash for software and configuration storage. A 16000-entry MAC table accommodates learned Ethernet destinations. Direct RJ-45 and USB mini-Type B console connections complement web Device Manager and remote SSH/Telnet access. DC-A and DC-B accept independent DC feeds, with the higher-voltage source powering the unit when both are active. 40W consumption measured at 9.6V must be included in the cabinet power allocation; an external power supply's output rating is not the switch's electrical draw.
ORM Systems supplies IE-4000-4TC4G-E in new sealed and certified refurbished condition, with up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on either condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify the required condition, quantity, and accessory PIDs on the purchase order. PO acceptance, Net-30 for government, and RMA with advance replacement support enterprise and volume orders, with stock and RMA coverage across the UK, EU, US, and MEA.

When several machine cells reuse the same private addresses, 1:1 static NAT provides an address-translation boundary without changing every endpoint. The switch supports 128 unique subnet translation entries. Before releasing the purchase order, map the required translations and stage the intended configuration against the actual address plan.
When multiple industrial cabinets need the same fault-signaling connections, two dry-contact alarm inputs and one relay output provide an interface for external monitoring. Open or closed input conditions are configurable. Specify the alarm wiring and required fault responses with the switch order rather than leaving those connections to installation.
When a maintenance team holds a replacement for an installed unit, configuration transfer can use SD-IE-1GB=, the 1 GB spare SD card. The front-accessible storage is removable. Confirm the saved configuration, SD-IE-1GB= requirements, and matching hardware identity before issuing the spare-unit purchase order.
PoE power for connected endpoints
IE-4000-4TC4G-E does not power endpoints. IE-3500-8P3S-E provides eight Gigabit PoE+ ports and three Gigabit SFP ports, changing both endpoint density and the uplink arrangement.
10G uplinks to the upstream network
The fixed combo uplinks reach 1G, not 10G, and there is no removable uplink-card bay. A 10G upstream requirement needs different switch hardware.
Sealed cabinets operating above 60°C
Sealed-enclosure operation is limited to 60°C, even though other enclosure conditions permit higher temperatures. Cabinet thermal design must remain within the sealed-enclosure limit.

IE-4000-4TC4G-E identifies an Industrial Ethernet 4000 switch with four Fast Ethernet combo access ports, four Gigabit combo uplinks, and LAN Base. IE-4000 names the family, 4TC identifies the Fast Ethernet copper-or-fiber combo group, and 4G identifies the Gigabit uplinks. The complete -E model ships with LAN Base.
IE-4000-4TC4G-E supports web Device Manager, Cisco IOS CLI through console connections or remote SSH/Telnet, Cisco Network Assistant, SNMP management, Industrial Network Director, and Cisco Catalyst Center. Local console access uses RJ-45 or USB mini-Type B. Cisco Catalyst Center capabilities depend on the selected Essentials or Advantage entitlement.
IE-4000-4TC4G-E is discontinued: end of sale was July 26, 2024, and the last date of support is July 31, 2029. Software maintenance ended July 26, 2025, while vulnerability and security support ends July 26, 2027. IE-3505-8T3S-E is the current migration model.
IE-4000-4TC4G-E is available new sealed with up to a 3-year extended ORM warranty, or certified refurbished with up to a 1-year ORM warranty. Both conditions carry 30-day returns; terms apply. Cisco's separate five-year limited hardware warranty is bounded by the last date of support, July 31, 2029.
IE-4000-4TC4G-E includes LAN Base; L-IE4000-RTU= or Cisco ONE Advanced Perpetual enables IP Services. Cisco ONE Foundation Lite and Foundation are additional perpetual options. Cisco DNA Essentials and Advantage have a one-year minimum term. Subscription orders and renewals end December 11, 2026; Cisco Catalyst Center Advantage does not require IP Services.
IE-4000-4TC4G-E accepts 9.6-60V DC at DC-A and DC-B; PWR-IE50W-AC= is a compatible external power supply. PWR-IE50W-AC= accepts 100-240V AC or 125-250V DC. The switch can use one DC source or two independent feeds, but those inputs are not two internal hot-swappable supply bays.
Cisco IE 4000 supports GLC-FE-100FX-RGD= for 100BASE-FX connections and GLC-SX-MM-RGD= for 1000BASE-SX connections. On IE-4000-4TC4G-E, Fast Ethernet optics belong in the access combo interfaces and Gigabit optics belong in the uplink combo interfaces. Match each transceiver to the fiber type, link distance, and operating temperature required by the installation.
Cisco Industrial Ethernet 4000 switches mount on DIN rail and can use STK-RACK-DINRAIL= for installation within a 482.6 mm rack. IE-4000-4TC4G-E remains a 155.4 mm-wide industrial unit, not a full-width 1U rack chassis. Specify STK-RACK-DINRAIL= when the order must include the rack's DIN rail mounting arrangement.
Cisco IE 4000 supports -40°C to 70°C in a vented enclosure and -40°C to 60°C in a sealed enclosure. A fan- or blower-equipped enclosure supports -34°C to 75°C. These are enclosure-dependent limits rather than one universal cabinet rating. Select the applicable enclosure limit and account for temperature reductions required by nonindustrial optics.
IE-4000-4TC4G-E provides IPv4 static routing with LAN Base, not the dynamic routing features of IP Services. OSPF, EIGRP, BGPv4, IS-IS, and RIPv2 require IP Services entitlement. PIM-SM and PIM-DM also belong to IP Services. Specify the required software entitlement separately rather than treating those protocols as included with the base hardware.
IE-4000-4T4P4G-E supplies four Fast Ethernet PoE+ ports, whereas IE-4000-4TC4G-E has no powered ports. The discontinued PoE model suits existing installations needing switch-supplied endpoint power; the non-PoE model suits independently powered equipment with copper-or-fiber access links. Both models reached end of sale on July 26, 2024.
IE-4000-8T4G-E has eight dedicated Fast Ethernet copper access ports, compared with four Fast Ethernet combo access ports on IE-4000-4TC4G-E. Both are discontinued models. IE-4000-8T4G-E suits an existing copper installation needing more access connections; IE-4000-4TC4G-E suits a smaller access count with selectable copper or fiber interfaces.
IE-3505-8T3S-E provides Gigabit copper access instead of the Fast Ethernet combo access on discontinued IE-4000-4TC4G-E. The current successor has eight copper access ports rather than four combo access ports. Existing media-dependent replacements call for the older configuration; new Gigabit copper-access deployments call for the successor.
