IE-4000-8GT4G-E is a DIN rail industrial switch with eight 10/100/1000 copper access ports and four fixed Gigabit combo uplinks for copper or fiber connections. The Industrial Ethernet 4000 runs Cisco IOS with LAN Base and provides Layer 2+ functionality through IPv4 static routing. Each combo uplink uses either its RJ-45 connection or its SFP cage, so the fiber and copper interfaces are alternatives rather than additional simultaneous links. Endpoints need their own power because this configuration does not provide PoE. The discontinued IE-4000-4GC4GP4G-E differs by adding four Gigabit PoE+ ports. Cisco Industrial Ethernet 4000 switching serves automation, transportation and substation networks where enclosure requirements govern equipment selection. Uplinks are built in, with no removable uplink card bay.
IE-4000-8GT4G-E price for new stock is $3,097.50, a 59.8% saving from the Cisco list price of $7,712.00. IE-4000-8GT4G-E refurb price is $1,270.50. IE-4000-8GT4G-E is in stock and available for next-day dispatch. (terms applied)

Line-rate forwarding on all ports and packet sizes avoids a reduced forwarding rating for smaller packets. A 16000-entry MAC table and support for 1000 VLANs define the switching scale for endpoint addressing and segmentation. IE-4000-8GT4G-E carries 1 GB of DRAM and 128 MB of onboard flash for runtime operation and image storage. 35W consumption, measured at 9.6V DC, provides the switch load to account for when selecting an external supply. Dual-feed DC inputs permit primary and secondary power connections without internal hot-swappable supply modules. OSPF, EIGRP, BGPv4 and IS-IS are not included in the supplied software tier. Web Device Manager supports browser configuration; Cisco IOS CLI provides console access and remote administration through SSH or Telnet. SNMPv3 and syslog provide monitoring interfaces, while DHCP snooping and Dynamic ARP Inspection support access security. EtherChannel provides link aggregation, and IGMP snooping controls multicast forwarding toward receiving ports.
IE-4000-8GT4G-E is available new sealed or certified refurbished, with ORM warranties up to three years extended for new units or up to one year refurbished, plus 30-day returns on every condition; terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot and optics bay recognition; firmware is verified and configuration wiped to factory default. Specify condition, quantity and accessories on the PO; Cisco’s separate five-year limited hardware warranty ends no later than July 31, 2029. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA in the UK, EU, US and MEA.

When several control cabinets must follow one configuration standard, the Industrial Ethernet 4000 supports CIP EtherNet/IP and PROFINET v2 alongside industrial macro configuration. Define the controller protocol, management addressing and configuration baseline for each site, then attach that baseline to the hardware purchase order.
An existing installation using removable configuration storage needs a spare that preserves the same recovery workflow. The included 1 GB SD card stores software and configuration, with SD-IE-1GB= available as the spare card. Specify the card, intended boot storage and configuration-loading procedure before ordering replacement hardware.
When a control cabinet must report local equipment conditions through the network, two dry-contact alarm inputs and one alarm output relay provide physical alarm connections. Define the monitored contact states and relay destination before staging the unit, then include the required alarm wiring in the purchase order.
PoE power for connected endpoints
IE-4000-8GT4G-E supplies no endpoint PoE. IE-3500-8P3S-E provides eight Gigabit PoE+ ports and three Gigabit SFP uplinks, replacing the four combo-uplink arrangement.
10G uplinks from the cabinet
IE-4000-8GT4G-E has Gigabit-only fixed uplinks and no uplink expansion bay. A 10G requirement cannot be met by fitting a different transceiver into the existing cages.
Dynamic routing under the included license
LAN Base on IE-4000-8GT4G-E supports IPv4 static routing, not OSPF, EIGRP or BGPv4. Those protocols require separate IP Services entitlement rather than the included license.

IE-4000-8GT4G-E identifies Industrial Ethernet 4000 hardware with eight Gigabit copper ports and four Gigabit combo uplinks. IE denotes Industrial Ethernet, 4000 the series, 8GT the copper access configuration and 4G the combo uplinks. The complete -E PID ships with LAN Base.
IE-4000-8GT4G-E is managed through Web Device Manager, Cisco IOS CLI over console, SSH or Telnet, Cisco Network Assistant, Industrial Network Director and SNMP. Catalyst Center management uses the corresponding Essentials or Advantage entitlement. Local console access is available through RJ-45 or USB mini-Type B connections.
IE-4000-8GT4G-E is discontinued, with end of sale on July 26, 2024 and software maintenance ending July 26, 2025. Security support ends July 26, 2027, and the last date of support is July 31, 2029. IE-3505-8T3S-E is the current migration PID.
IE-4000-8GT4G-E is offered new sealed or certified refurbished, with ORM warranties of up to three years extended for new units and up to one year for refurbished units. Returns are available for 30 days in either condition; terms apply. Cisco’s five-year limited hardware warranty cannot extend beyond July 31, 2029.
IE-4000-8GT4G-E includes LAN Base, with IP Services available through L-IE4000-RTU=. Additional paths include Cisco ONE Foundation Lite Perpetual, Foundation Perpetual and Advanced Perpetual suites, plus Catalyst Center Essentials or Advantage subscriptions starting at three years. Catalyst Center Advantage does not require IP Services; specify software entitlements separately from hardware.
IE-4000-8GT4G-E takes redundant external DC feeds across a 9.6–60V DC range, rather than internal AC power modules. PWR-IE50W-AC= is a compatible 50W external converter for an AC-fed installation. Specify the converter or site DC source, plus the intended primary and secondary wiring, on the purchase order.
IE-4000-8GT4G-E has four fixed Gigabit combo uplinks, each selecting its RJ-45 interface or SFP interface rather than operating both simultaneously. Copper supports 10/100/1000 operation; the SFP interface supports 100/1000 operation with compatible optics. Specify the active medium and fiber transceiver for each uplink before ordering.
IE-4000-8GT4G-E supports IPv4 static routing under its included LAN Base license, placing the supplied configuration in Layer 2+. OSPF, EIGRP, BGPv4 and IS-IS belong to the separate IP Services feature set. A purchase requiring dynamic routing must include verification of the appropriate software entitlement.
Industrial Ethernet 4000 supports -40°C to 70°C in vented enclosures, -40°C to 60°C in sealed enclosures and -34°C to 75°C in fan- or blower-equipped enclosures. The applicable limit depends on the enclosure, not just ambient room temperature. Nonindustrial transceivers require additional temperature derating.
IE-4000-8GT4G-E has no PoE output, while IE-4000-4GC4GP4G-E provides four Gigabit PoE+ ports with a shared 125W budget. Both models are discontinued. The first fits existing installations with separately powered endpoints; the second fits like-for-like replacement where four powered connections are required.
IE-4000-16GT4G-E provides sixteen Gigabit copper access ports compared with eight on IE-4000-8GT4G-E; both retain four Gigabit combo uplinks. Both models are discontinued. The smaller model matches eight-connection cabinets, while the larger model matches existing cabinets needing sixteen copper endpoint connections.
IE-3505-8T3S-E provides three dedicated Gigabit SFP uplinks, whereas IE-4000-8GT4G-E provides four Gigabit combo uplinks. IE-3505-8T3S-E is the current migration PID. The discontinued IE-4000-8GT4G-E suits like-for-like replacement; the successor suits a refresh where three fiber uplinks meet the connection plan.
