IE-1000-4T1T-LM Description
The IE-1000-4T1T-LM is a Cisco Industrial Ethernet 1000 Series compact rugged switch that carries 5 Fast Ethernet copper ports, arranged as 4 downlinks plus 1 uplink, in a 38 mm-wide DIN rail housing built for operational technology teams that manage equipment through a web GUI rather than a command line. It is the entry model of Cisco's lightly managed industrial line, positioned for machine builders and machine-to-machine installations that need VLANs, IGMP snooping, port security, and EtherNet/IP (CIP) awareness without the configuration depth of a fully managed industrial switch. The switch runs from a 12-24V supply with redundant voltage feed support, draws 4.2W, boots to operation in 50 seconds, and operates from -20°C to +70°C in a vented enclosure, which places it inside small automation panels, building risers, and roadside cabinets where space and power are limited and no PoE output is required.

Product Performance
Key Features
At 5.0 x 1.50 x 4.5 in and 1.10 lb, this is the narrowest and lightest IE 1000 model, so it fits automation panels where the DIN rail is already crowded with relays, PLCs, and terminal blocks.
Configuration and monitoring run through the web device manager with SNMP v2/v3 and syslog behind it, so plant electricians and OT technicians can own the switch without CLI training or IT escalation.
Plug-and-Play provisioning and zero-touch IP discovery or DHCP addressing let a replacement or new panel switch join the network with its configuration applied automatically, which shortens commissioning on serially built machines.
The 12-24V input with redundant voltage feed support runs directly from the low-voltage DC rails already present in control panels, avoiding a dedicated higher-voltage supply class for a data-only switch.
IEEE 802.1x in single-host mode with MAC authentication bypass, Sticky-MAC port security, and TACACS+/RADIUS clients keep unauthorized laptops and devices off open panel ports at the machine edge.
Hazardous-location compliance (ANSI/ISA 12.12.01 Class 1 Div 2, ATEX/IECEx Zone 2 with a cabinet enclosure), IP30 housing, and NEMA TS-2 alignment let the same model serve plant, process, and roadside cabinet installs.
Application Scenarios
Installed inside the control panel of serially produced machines, connecting the PLC, HMI, and local I/O of one machine and handing traffic upward through the single Fast Ethernet uplink.
Deployed in electrical and telecom risers to aggregate a handful of building automation controllers onto the facility network, where four copper ports cover the floor’s controller count.
Mounted in intelligent transportation system cabinets at intersections, linking signal controllers and detection equipment that draw power locally rather than over Ethernet.

- The IE-1000-4T1T-LM and IE-1000-6T2T-LM split on capacity alone: the same 12-24V data-only design either carries 4 downlinks with a single uplink or 6 downlinks with a redundant pair of uplinks, so a panel that needs a second uplink path or more than four devices moves up to IE-1000-6T2T-LM.
- Against IE-1000-4P2S-LM, the same four-downlink class changes power role entirely: the 4P2S adds a 120W PoE budget, swaps to 2x 1G SFP fiber uplinks, needs a 48-54V input, and extends the vented operating floor from -20°C to -40°C, which makes it the pick when the panel powers cameras or access points or when the uplink must leave the cabinet on fiber.
- For deciding which SKU to order, settle the power question first, since PoE and the 48-54V supply class separate IE-1000-4P2S-LM from both data-only models, then size the downlink and uplink count between IE-1000-4T1T-LM and IE-1000-6T2T-LM; management model does not separate this group because every IE 1000 is web-managed.
Selection Guide
1. When One Uplink Covers The Panel
A machine or riser panel with at most four wired devices and a single upstream path runs on the IE-1000-4T1T-LM’s 4+1 Fast Ethernet layout; a design that needs uplink redundancy or two more access ports belongs on IE-1000-6T2T-LM instead.
2. PoE Or Fiber Forces The P Models
The moment endpoint power over Ethernet or a fiber uplink enters the design, this data-only copper model is out of scope; IE-1000-4P2S-LM keeps the same four-downlink footprint while adding a 120W PoE budget and 2x 1G SFP uplinks reaching up to 80 km.
3. Cold-Start Boundary At -20°C
This model’s vented-enclosure floor is -20°C (-16°C with forced airflow), which suits indoor plants and tempered cabinets; unheated outdoor enclosures that see -40°C conditions need the PoE models’ wider envelope rather than this SKU.
4. Lightly Managed Scope Limit
The IE 1000 line covers web-GUI operation with VLANs, IGMP snooping, and port security; designs that require CLI automation, routing, or ring protocols beyond spanning tree sit with Cisco’s fully managed Industrial Ethernet families rather than any IE 1000 model.
Ordering Checklist

Check Item 3391_b3cc24-16> |
What to Confirm 3391_1d5104-a5> |
Why It Matters 3391_4c9f4c-9c> |
|---|---|---|
|
Power supply class 3391_824d42-75> |
Pair the switch with a 50W DIN rail supply such as PWR-IE50W-AC= sized for the 12-24V input. 3391_08999c-47> |
An underrated or wrong-class supply is the most common cause of a dead panel switch at first power-on. 3391_3d5cec-e3> |
|
Hazardous-location kit 3391_abaa1c-6e> |
Use PWR-IE50W-AC= rather than PWR-IE50W-AC-L= when the cabinet sits in a Class 1 Div 2 area, and plan the required enclosure. 3391_289385-e9> |
The -L supply is IP20 rated and carries no hazardous-location certification, which fails site acceptance in classified zones. 3391_e4be76-cd> |
|
Enclosure thermal class 3391_adabff-91> |
Match the enclosure type to the temperature tier: -20°C to +70°C vented, -20°C to +60°C sealed, -16°C to +75°C with forced airflow. 3391_7f6bc8-a8> |
A sealed cabinet in a hot plant can push the switch past its derated ceiling even though the model number is correct. 3391_6828d0-39> |
|
Uplink media plan 3391_da22d6-f1> |
Confirm the upstream run is Fast Ethernet copper; this model has no SFP slot. 3391_a3c707-4e> |
A fiber backhaul discovered at install time cannot be retrofitted onto this SKU. 3391_68e81d-ea> |
|
Rack adaptation 3391_5cc2f7-38> |
Add STK-RACK-DINRAIL= only when the switch must mount in a 19-inch rack instead of a DIN rail. 3391_dbec1e-22> |
The switch ships as a DIN rail device; rack installs stall without the adapter kit. 3391_d2f817-7f> |

Cisco IE 1000 Switch Rear Panel
The rear panel of the switch has a latch for installation on a DIN rail. See photo. The latch is spring-loaded to move down to position the switch over a DIN rail and return to the original position to secure the switch to a DIN rail.
