IE-4000-16GT4G-E combines 16 Gigabit copper access ports and four fixed Gigabit combo uplinks in a DIN Rail industrial switch for separately powered equipment. Each uplink selects copper or fiber rather than providing two simultaneous connections, so the media choice does not create additional logical ports. The Industrial Ethernet 4000 runs Cisco IOS with LAN Base and provides Layer 2+ operation for industrial access. Manufacturing, energy, and transportation deployments can use its compact mounting arrangement where a conventional rack chassis is unsuitable. The discontinued IE-4000-8GT8GP4G-E differs by providing eight PoE+ downlinks, whereas this configuration supplies no endpoint power. Copper access density is fixed at purchase: the chassis does not provide an access-port expansion bay for adding another bank of connections later.
IE-4000-16GT4G-E price for new stock is $3,447.15, a 68.3% saving from the Cisco list price of $10,874.00. IE-4000-16GT4G-E refurb price is $2,409.75. IE-4000-16GT4G-E is in stock and available for next-day dispatch. (terms applied)

20 Gbps nonblocking switching capacity supports traffic across the fixed interfaces, while line-rate forwarding applies to every packet size. 40W power consumption, measured at the lower input-voltage limit, establishes the switch allowance when sizing an external supply alongside other cabinet loads. IPv4 static routing supports manually defined inter-subnet paths; OSPF and EIGRP are not included in the base feature set. IE-4000-16GT4G-E has 1 GB DRAM and 128 MB onboard flash, separating working memory from persistent onboard storage. The address table holds 16000 unicast MAC entries, and four egress queues support traffic scheduling. STP and LACP provide loop control and link aggregation, while IGMP snooping controls multicast forwarding. Two alarm inputs and one relay output connect external contact monitoring to the network device. Configuration is available through the embedded web interface and command-line access, with SNMP providing a separate network-management path.
IE-4000-16GT4G-E is offered new sealed or certified refurbished: ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns for every condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, optics bay recognition, and clean boot, with firmware verified and configurations wiped to factory default; Cisco's separate five-year limited hardware warranty cannot extend beyond July 31, 2029. Specify condition, quantities, and required accessories on the PO. For enterprise and volume orders, POs are accepted, government customers receive Net-30, and RMA with advance replacement covers UK, EU, US, and MEA.

When a new control cabinet is being laid out, equipment spacing becomes an ordering constraint rather than an afterthought. Allow 50.8 mm above, below, on both sides, and in front of the unit, with unobstructed airflow. Check the cabinet arrangement and cable access before releasing the PO.
When machines reuse address ranges across separate production cells, 1:1 static NAT can translate those addresses at the industrial edge. The translation resource supports 128 unique subnet entries rather than an unlimited mapping set. Prepare the required subnet translations and check that allocation against the design before specifying hardware and software.
When an installed industrial network needs like-for-like spares, the removable SD card carries the software image and configuration used for replacement. Include SD-IE-1GB= in the spare-parts schedule when an additional card is required. Before the PO, specify the card requirement and retain an approved configuration backup for the replacement procedure.
PoE-powered endpoint connections
IE-4000-16GT4G-E supplies no PoE output. IE-3500-8P3S-E provides eight Gigabit PoE+ ports and three SFP uplinks, so its base copper port count differs materially.
10G uplinks to aggregation
IE-4000-16GT4G-E has fixed Gigabit combo uplinks and no removable uplink bay. A 10G aggregation connection exceeds the uplink capability of this model.
Dynamic routing without license upgrades
LAN Base supports IPv4 static routes rather than OSPF or EIGRP. Dynamic routing requires IP Services through L-IE4000-RTU=; that feature tier is not included with the base configuration.
Ongoing platform software maintenance
IE-4000-16GT4G-E software maintenance ended July 26, 2025. Its current migration model, IE-3505-8T3S-E, has eight copper access ports and three SFP uplinks, requiring a density check.

IE-4000-16GT4G-E identifies an Industrial Ethernet 4000 switch with 16 Gigabit copper downlinks, four Gigabit combo uplinks, and LAN Base software. IE-4000 is the family prefix, 16 is the downlink count, GT identifies Gigabit copper, and 4G identifies the combo uplinks; the E model ships with LAN Base.
Industrial Ethernet 4000 supports Web Device Manager, CLI over console, SSH or Telnet, SNMP, Cisco Network Assistant, Industrial Network Director, licensed Catalyst Center, CIP-based tools, and PROFINET automation software such as Siemens STEP 7. RJ-45 or mini-USB provides local console access. Controller Essentials adds basic assurance; controller Advantage adds automation and analytics.
IE-4000-16GT4G-E ended sale on July 26, 2024, and Cisco's last support date is July 31, 2029. Software maintenance ended July 26, 2025, while security support is scheduled to end July 26, 2027. The current migration product is IE-3505-8T3S-E, which requires a port-density check rather than being a like-for-like fixed replacement.
IE-4000-16GT4G-E is offered new sealed or certified refurbished. ORM warranties are up to a 3-year extended warranty for new units and up to 1 year refurbished; returns are 30 days for every condition, terms apply. Cisco's separate five-year limited hardware warranty is subject to eligibility and ends no later than July 31, 2029.
LAN Base is included with IE-4000-16GT4G-E; IP Services is a paid upgrade. Cisco ONE Foundation Lite, Foundation, and Advanced are perpetual options, with Advanced including IP Services. Catalyst Center Essentials and Advantage subscriptions start at three years. Catalyst Center Advantage does not require IP Services, so controller licensing and dynamic-routing entitlement remain separate.
Four 1G combo uplinks are built into IE-4000-16GT4G-E, with each connection using either its RJ-45 interface or its SFP interface. Both interfaces of a pair cannot operate simultaneously. GLC-SX-MM-RGD= supports industrial multimode connections, while GLC-LX-SM-RGD= supports industrial single-mode connections. Specify the fiber type and matching optical parts on the order.
Two independent DC inputs power the Industrial Ethernet 4000, accepting 9.6-60V DC. An external PWR-IE50W-AC= can convert AC mains to a suitable DC supply. Power redundancy comes from external feeds rather than internally installed redundant PSU modules. Confirm the input wiring, grounding, and external power arrangement before specifying the purchase.
OSPF and EIGRP require IP Services on IE-4000-16GT4G-E; the included LAN Base tier provides IPv4 static routing. L-IE4000-RTU= is the software upgrade from LAN Base to IP Services. The upgraded tier also adds BGPv4, IS-IS, and PIM-SM. Specify the required entitlement separately rather than treating the base hardware PID as a dynamic-routing license.
Industrial Ethernet 4000 mounts on a DIN rail, with STK-RACK-DINRAIL= providing a rack-mounted rail option. The 155.4 mm-wide chassis is not a full-width rack switch. Its installation needs 50.8 mm clearance above, below, at both sides, and in front. Include the mounting accessory and verify available space before ordering.
Yes, Industrial Ethernet 4000 includes 1:1 static NAT with LAN Base and supports bidirectional translation using 128 unique subnet entries. That resource is a subnet-translation limit, not an IPv4 routing-table figure. Prepare the translation plan around the required production-cell address mappings and validate those mappings before ordering hardware or additional software licenses.
IE-4000-8GT8GP4G-E provides eight Gigabit PoE+ downlinks where IE-4000-16GT4G-E provides no endpoint power. Both models are discontinued. The PoE model has a shared 240W endpoint budget; the non-PoE model serves separately powered equipment. Existing installations should match the replacement to their endpoint-power requirement rather than choosing from port count alone.
IE-4000-16GT4G-E uses copper-or-fiber combo uplinks, while IE-3505-8T3S-E uses dedicated SFP uplinks. IE-3505-8T3S-E is the current migration model for the discontinued IE-4000-16GT4G-E. The older model suits like-for-like installed-fleet sparing; the successor suits a platform migration where the buyer has checked the access-port allocation and optical connection requirements before selecting the base chassis.
