IE-2000-4T-B provides managed industrial access through four 10/100BASE-T downlinks and two fixed 10/100BASE-T copper uplinks. The non-PoE DIN rail switch belongs to the Cisco Industrial Ethernet 2000 Series and ships with LAN Base for Layer 2+ operation. Programmable logic controllers, human-machine interfaces, drives, and sensors connect through its copper interfaces. The discontinued IE-2000-4T-L instead carries LAN Lite, so matching the enclosure and physical connections alone does not establish software equivalence. The fixed configuration has neither SFP cages nor a removable uplink card bay. Connected equipment must receive power independently rather than through the Ethernet ports.
IE-2000-4T-B price for new stock is $451.50, a 71.9% saving from the Cisco list price of $1,609.00. IE-2000-4T-B refurb price is $889.34. IE-2000-4T-B is in stock and available for next-day dispatch. (terms applied)

IPv4 static routing supports fixed inter-subnet paths under the included license; OSPF and EIGRP require IP Lite rather than a configuration-only change. IE-2000-4T-B carries 256 MB of DRAM and 64 MB of onboard flash for its operating image and configuration. A 2 MB egress buffer accommodates queued packets, while the forwarding hardware supports 8000 unicast MAC addresses. Web Device Manager, Cisco IOS CLI, and SNMP provide administration paths. Local RJ-45 and USB mini-Type B console connections remain separate from Ethernet traffic interfaces. The IE 2000 also supports CIP-based management tools and PROFINET automation software for integration with industrial control systems.
Specify IE-2000-4T-B in new sealed or certified refurbished condition, and include the required power source and mounting accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, a clean boot, and every copper port linking at its rated speed. New units carry ORM's up to 3-year extended warranty, certified refurbished units carry up to 1 year, and both conditions include 30-day returns; terms apply. Submit quantities and condition requirements for enterprise or volume orders: PO accepted, Net-30 for government, RMA with advance replacement, and regional stock and RMA coverage across the UK, EU, US, and MEA.

An existing control cabinet that needs network equipment connected to its alarm circuits can use the switch's two dry-contact alarm inputs and one alarm output relay. Input contacts can represent open or closed conditions. Specify the alarm wiring, contact behavior, and external alarm-device requirements before the purchase order.
A staging bench preparing replacement units can use SD-IE-1GB= to retain software and configuration changes outside the switch's internal storage. The optional 1 GB card is not included by default. Specify SD-IE-1GB= separately and establish the configuration-transfer procedure before ordering the staged units.
Installed equipment retained beyond July 26, 2027 will pass this model's scheduled vulnerability and security support milestone. That date matters to a spare-stock purchase independently of whether a unit still boots or passes a port test. Specify the intended retention horizon and verify service entitlements before the purchase order.
Gigabit links throughout the cabinet
IE-2000-4T-B limits Ethernet links to 100 Mbps. IE-3100-4T2S-E supplies four Gigabit copper ports and two Gigabit SFP uplinks, changing the upstream connection medium.
PoE endpoints without independent power
IE-2000-4T-B cannot power endpoints through Ethernet. Independent endpoint power must be specified; changing the external DC source does not add powered Ethernet ports.
OSPF in the included software image
LAN Base on IE-2000-4T-B includes static IPv4 routing, not OSPF. Dynamic routing requires the discontinued LIC-IE2000-IP-L= upgrade and a valid upgrade entitlement.
Cisco support beyond July 2029
IE-2000-4T-B reaches its last Cisco support date on July 31, 2029. IE-3100-4T2S-E is the migration replacement; existing entitlements cannot extend the older hardware's cutoff.

Durable and dependable industrial Ethernet switch.
IE-2000-4T-B identifies the Industrial Ethernet 2000 family, the 4T six-port Fast Ethernet copper configuration, and the B LAN Base license. Four Ethernet ports are downlinks and two are uplinks. The configuration segment therefore does not mean that the switch has only four physical Ethernet ports in total.
IE-2000-4T-B supports Web Device Manager over HTTPS, Cisco IOS CLI through console or SSH/Telnet, SNMP, Cisco Network Assistant, Cisco Prime Infrastructure/LMS, and Cisco Catalyst Center. Industrial management also supports CIP-based tools and PROFINET automation software. Local console access uses RJ-45 or USB mini-Type B connections.
IE-2000-4T-B is discontinued: end of sale was July 26, 2024, and eligible Cisco support ends July 31, 2029. Software maintenance ended July 26, 2025; scheduled vulnerability and security support ends July 26, 2027. IE-3100-4T2S-E is the replacement, with Gigabit copper access and Gigabit SFP uplinks.
IE-2000-4T-B is offered new sealed or certified refurbished, with ORM's new-unit warranty up to 3 years extended and refurbished warranty up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's separate five-year limited hardware warranty remains subject to entitlement and cannot extend beyond July 31, 2029.
LAN Base is included with IE-2000-4T-B, while optional Catalyst Center Essentials subscriptions use a three-year minimum term. IP Lite routing requires LIC-IE2000-IP-L=, an upgrade discontinued July 26, 2024. A centralized-management subscription does not substitute for the network software license; verify existing upgrade entitlements separately before ordering.
No, IE-2000-4T-B does not provide PoE or PoE+ on any Ethernet port. Attached phones, cameras, sensors, or access points requiring power must receive it independently. The switch also uses external DC power for its own operation; an Ethernet connection is not its power-input method.
IE-2000-4T-B has two fixed 10/100BASE-T copper uplinks, not Gigabit Ethernet or fiber uplinks. No SFP transceiver or removable uplink card can change those interfaces. Use copper cabling within the 100 m link limit and confirm that upstream equipment supports the required Fast Ethernet connection.
Industrial Ethernet 2000 switches accept external DC power through DC-A and DC-B terminal connectors; one feed can operate IE-2000-4T-B. Independent sources provide feed redundancy, with the higher-voltage source supplying power when both are available. PWR-IE50W-AC= is a compatible external converter, not an internal redundant PSU.
IE-2000-4T-B does not include OSPF or EIGRP under LAN Base; its included routing capability is IPv4 static routing. OSPF, EIGRP, and RIP belong to IP Lite. LIC-IE2000-IP-L= was discontinued, so an order requiring dynamic routing needs a verified valid upgrade entitlement rather than an assumption about the hardware.
Industrial Ethernet 2000 uses DIN rail mounting, and IE-2000-4T-B includes a rear spring-loaded latch. Wallmount-IE2k-04= provides the wall-mount alternative; STK-RACK-DINRAIL= provides a rack-mounted DIN rail arrangement. The chassis itself is not a full-width rack switch. Preserve the required clearances when specifying the enclosure.
IE-2000-16PTC-G-E provides four PoE+ ports within sixteen Fast Ethernet downlinks, whereas IE-2000-4T-B has no powered ports. Both models are discontinued, making this a retained-equipment comparison rather than a current-product recommendation. The larger model suits powered-endpoint requirements; the smaller model suits independently powered, low-port-count equipment.
IE-2000-4T-B includes LAN Base, while IE-2000-4T-L includes LAN Lite with the same six Fast Ethernet copper ports. The license distinction matters when matching an existing configuration, not just an enclosure. Both are discontinued; LAN Base suits static-routed installations, while LAN Lite suits LAN Lite switching-only replacement requirements.
IE-3100-4T2S-E provides four Gigabit copper ports and two Gigabit SFP uplinks, replacing IE-2000-4T-B's six Fast Ethernet copper ports. The successor changes link speed and uplink medium, so it is not a connector-for-connector substitution. Retained copper-only Fast Ethernet installations favor the discontinued model; Gigabit migration favors the successor.
