Cisco Industrial Ethernet 2000U IE-2000U-4S-G 4-Port Fiber Data DIN-Rail Switch with 2x 1G SFP, LAN Base
- Switch, Managed, 4 x 100 Mbit SFP + 2 x 1000Base-X SFP (uplink), DIN Rail Mountable
Overview
The Cisco Industrial Ethernet 2000U Series is a line of compact, fanless, ruggedized DIN-rail access switches for substation, utility, and factory-floor networks, running classic Cisco IOS for familiar management and long-term investment protection. The IE-2000U-4S-G is the all-fiber six-port configuration, with four Fast Ethernet SFP downlinks and two Gigabit Ethernet SFP uplinks, shipping with the LAN Base image for Layer 2 switching. Its all-fiber design suits long cable runs and electrically noisy environments where copper is impractical. As a four-downlink model it does not include IEEE 1588v2 PTP or Parallel Redundancy Protocol, which are reserved for the eight- and sixteen-port models; its universal wide-range 12-48 VDC input and convection cooling give it resiliency with no moving parts. Layer 3 routing is added later as a field-upgradable, perpetual IP Services license rather than a hardware change.
Technical Details
The Cisco Industrial Ethernet 2000U IE-2000U-4S-G is a Layer 2 managed hardened DIN-rail switch with four Fast Ethernet SFP fiber downlink ports and two Gigabit Ethernet SFP uplink ports, running Cisco IOS with the LAN Base license. Switching capacity is 7.6 Gbps and the forwarding rate is 5.66 Mpps. It carries no Power over Ethernet, so all four access ports are data-only. It has neither IEEE 1588v2 PTP nor Parallel Redundancy Protocol, which are reserved for the 8-port and 16-port models. It accepts a redundant wide-range 12-48 VDC power input and operates from -40°C to +70°C in a vented enclosure. As an all-fiber switch it connects industrial and OT devices such as PLCs, HMIs, drives, and industrial sensors over Fast Ethernet fiber in substations and on the factory floor.
Best For
The IE-2000U-4S-G suits harsh industrial and utility sites such as substations and factory floors that connect OT devices such as PLCs, HMIs, drives, and industrial sensors entirely over fiber, whether for long distances, electrical isolation, or immunity to interference. Its LAN Base image covers resilient Layer 2 features such as REP and FlexLink, and its redundant 12-48 VDC input and -40°C to +70°C operating range fit unconditioned enclosures.
Not suitable if:
- you need copper RJ45 access ports rather than fiber SFP downlinks
- you need Power over Ethernet to power devices such as ruggedized IP cameras or industrial wireless access points, since this is a data-only switch
- you need Parallel Redundancy Protocol or IEEE 1588v2 PTP, since those are available only on the 8-port and 16-port IE 2000U models
- you need Layer 3 routing out of the box, since routing requires the optional IP Services upgrade license
- you need more than four access ports

FAQ
Does the Cisco IE-2000U-4S-G support PoE?
No. The Cisco IE-2000U-4S-G is a data-only, all-fiber switch and none of its ports provide Power over Ethernet. It cannot power devices such as ruggedized IP cameras, industrial wireless access points, or IP phones. If you need PoE or PoE+ on the Fast Ethernet downlinks, the IE-2000U-16TC-GP is the PoE-capable model in the IE 2000U line, delivering IEEE 802.3af PoE and 802.3at PoE+ on up to four of its Fast Ethernet downlink ports from a separate external DC power source.
What transceivers does the IE-2000U-4S-G use?
The Cisco IE-2000U-4S-G is an all-fiber switch. Its four Fast Ethernet downlink ports accept 100BASE Fast Ethernet SFP transceivers and its two Gigabit uplink ports accept 1000BASE Gigabit SFP transceivers, both from Cisco's industrial-temperature GLC rugged (RGD) range. The Fast Ethernet SFP slots do not accept Gigabit-only SFPs, and the Gigabit uplinks do not accept Fast Ethernet-only SFPs. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
Can the IE-2000U-4S-G be stacked?
No. The Cisco IE-2000U-4S-G does not support switch stacking. High availability on the IE 2000U comes from ring and hub-and-spoke resiliency protocols rather than stacking: it supports Resilient Ethernet Protocol (REP) and FlexLink for fast reconvergence, along with Rapid Spanning Tree. Redundant wide-range DC power inputs add hardware resiliency. It cannot be combined into a single logical stack with other IE 2000U switches or any other Cisco series.
What is the difference between the IE-2000U-4S-G and the IE-2000U-4TS-G?
The IE-2000U-4S-G and IE-2000U-4TS-G are both six-port, LAN Base, data-only IE 2000U switches with two Gigabit SFP uplinks and neither IEEE 1588 nor PRP. They differ in downlink media: the 4S-G is all-fiber, with four Fast Ethernet SFP downlink ports, while the 4TS-G uses four 10/100 copper RJ45 downlinks. Choose the 4S-G for all-fiber industrial runs and electrically noisy environments, and the 4TS-G where devices connect over copper.
What license does the IE-2000U-4S-G ship with, and how do I add Layer 3 routing?
The Cisco IE-2000U-4S-G ships with the LAN Base Cisco IOS image, which provides Layer 2 switching, security such as 802.1x, DHCP snooping, dynamic ARP inspection, IP source guard and port security, QoS, and resiliency features such as REP, FlexLink, and xSTP. It has no IPv4 or IPv6 routing at LAN Base. Layer 3 routing is added with the field-upgradable IP Services license (PID SIEUISK9T-15002EK=), which enables static and inter-VLAN routing, RIP v1/2, EIGRP, OSPF, IS-IS, BGPv4, HSRP, policy-based routing, Multi-VRF CE (VRF-lite), PIM sparse and dense mode multicast, and IPv6 routing.
Does the IE-2000U-4S-G require a subscription to operate?
No. The Cisco IE-2000U-4S-G does not require any term subscription; it runs on its perpetual LAN Base Cisco IOS image indefinitely. Layer 3 routing is unlocked by an optional one-time IP Services software upgrade license (PID SIEUISK9T-15002EK=), which is a perpetual, field-upgradable license rather than a recurring subscription. There is no cloud entitlement or subscription term that can expire and disable base switching. Once IP Services is installed, its routing features remain enabled permanently.
What are the operating temperature and environmental ratings of the IE-2000U-4S-G?
The Cisco IE-2000U-4S-G is a hardened, fanless switch for industrial and utility environments. Its operating temperature range is -40°C to +70°C in a vented enclosure, -40°C to +60°C in a sealed enclosure, and -34°C to +75°C in a fan- or blower-equipped enclosure. It mounts on a DIN rail, is rated IP30 for ingress protection, and is convection cooled with no fans or moving parts. It accepts a redundant wide-range 12-48 VDC power input (9.6-60 VDC maximum) and provides dual alarm inputs and a relay output. It also meets IEC 61850-3 and IEEE 1613 substation standards. If non-industrial-temperature SFPs are installed, the maximum operating temperature must be derated.
Is the Cisco IE-2000U-4S-G end of life?
Yes. Cisco has announced end-of-sale for the Cisco Industrial Ethernet 2000U Series. The last day to order the IE-2000U-4S-G through Cisco was July 26, 2024, and Cisco's last date of support is July 31, 2029. Cisco positions the Catalyst IE3300 and the broader Catalyst IE3x00 rugged series as the migration path for IE 2000U deployments. Units remain fully supportable until the end-of-support date, and Network Devices Inc. continues to supply new, factory-sealed IE-2000U-4S-G switches while inventory is available.
What condition is the IE-2000U-4S-G sold in, and what warranty applies?
The Cisco IE-2000U-4S-G is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy. Each unit includes the required industrial-grade SD flash card as shipped by Cisco.
