PRODUCT DESCRIPTION
Eight-port industrial connectivity with Stratix 2500 management
Allen-Bradley 1783-LMS8 is a Stratix 2500 lightly managed Ethernet switch with eight copper 10/100Base-T ports. It connects industrial network devices while providing configuration and diagnostic functions through the supported Device Manager and Studio 5000 environments.
The switch requires a suitable DC supply, protective enclosure and correctly grounded DIN-rail installation. When replacing an installed unit, retain its network settings and verify the connected devices, port configuration and firmware before restoring machine or process communications.

Manuals & support
STRATIX 2500
Preserve port settings and the installed network design
Confirm eight copper Fast Ethernet ports are sufficient for the network. Use the approved device addresses, port roles and configuration tools rather than importing a different Stratix family configuration.
Mount and earth the switch in the specified enclosure, maintain ventilation clearances and connect the SELV DC supply with correct polarity. Follow the documented electrical safety precautions before working on connections.
Restore the approved firmware and switch configuration. Check VLAN membership, speed and duplex, device links and diagnostic status before reconnecting production traffic.
Features:
- Port and media match
- Protected DC installation
- Network configuration validation
The Allen-Bradley 1783-LMS8 requires application checks before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
The current official product record identifies 1783-LMS8 as Active. No discontinuation date or verified drop-in successor is asserted for this switch.
Evaluate a proposed change against port count and speed, management features, VLAN design and the connected control system. A matching connector count does not establish configuration or functional interchangeability.
Back up the installed switch settings and verify the new unit in the actual network. Confirm the stock-item origin from its label and order documents because the official catalog lists multiple origins.
Features:
- Active product record
- No assumed model interchangeability
- Configuration backup and test
The Allen-Bradley 1783-LMS8 requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 1783-LMS8
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Does 1783-LMS8 provide gigabit or fiber ports?
No. This catalog is the eight-port copper 10/100Base-T Stratix 2500 switch. Do not substitute gigabit or SFP capabilities from another Stratix model. -
What supply is required for this eight-port switch?
The installation instructions specify 12 to 24 V DC at 0.4 to 0.2 A from a SELV source. Check polarity, conductor rating and the specified terminal torque before energizing. -
Can I mount the switch without an enclosure?
No. It is supplied as open-type indoor equipment and requires a suitable enclosure. Maintain 50.8 mm clearance at the top, bottom and front and 25.4 mm at the sides for ventilation. -
Why is a newly connected port amber before it becomes green?
The instructions explain that Spanning Tree Protocol can take up to 30 seconds to discover the topology and check for loops. If the link does not establish, check device power, cabling and the attached adapter. -
Should one end use autonegotiation and the other a forced duplex setting?
Avoid that mismatch. The installation instructions recommend autonegotiating speed and duplex at both ends, or manually setting compatible speed and duplex parameters at both ends. -
How many VLANs can the Stratix 2500 configuration contain?
The user manual permits a maximum of 64 VLANs. Preserve access to the management VLAN and apply suitable port roles before changing VLAN assignments. -
Does the official catalog require an immediate replacement model?
The current official 1783-LMS8 record lists Active status. No verified discontinuation date or mandatory successor is asserted; check firmware and the application configuration before any hardware change.
