Product Overview
The Allen-Bradley 1783-US8TG2GX is a Gigabit unmanaged Ethernet switch from the Rockwell Automation Stratix 2000 family. It provides eight 10/100/1000 Mbps copper Ethernet connections and two additional Gigabit Ethernet SFP slots for fiber network expansion.
Unlike the 1783-US6T2TG2F and 1783-US6T2TG2H models, which use preinstalled Fast Ethernet fiber transceivers, the 1783-US8TG2GX supports Gigabit Ethernet optical connections through separately installed SFP modules. This makes it suitable for industrial networks requiring higher-speed communication between local equipment and remote network segments.
The switch uses an unmanaged operating architecture, allowing connected devices to exchange Ethernet traffic without requiring advanced network configuration. Its Gigabit copper interfaces support communication with PLCs, industrial computers, operator terminals, and other Ethernet-enabled equipment.
Two of its copper connections are shared combo interfaces with the corresponding SFP slots. This arrangement allows the network installer to select copper or optical connectivity according to the installation requirements.
The 1783-US8TG2GX is particularly useful in industrial control cabinets and manufacturing networks where Gigabit communication and optional fiber connectivity are required.

Working Principle
The 1783-US8TG2GX operates as an unmanaged Gigabit Ethernet switch. It receives Ethernet frames from connected devices, examines their destination MAC addresses, and forwards the traffic through the appropriate network interfaces.
Its eight copper Gigabit Ethernet connections support 10/100/1000 Mbps communication. These interfaces can connect industrial controllers, engineering computers, operator terminals, and other compatible Ethernet devices.
The two additional SFP slots support Gigabit optical connectivity through separately installed compatible SFP modules. Once the appropriate modules and fiber cables are installed, the switch can exchange Ethernet traffic with remote network equipment through optical connections.
The two combo interfaces share their copper and SFP connectivity. When an SFP module is used in a combo interface, the corresponding copper connection is not an independent additional network connection.
A typical communication arrangement is:
PLC / HMI / Industrial PC → 1783-US8TG2GX → Gigabit Copper Ethernet or Fiber SFP → Remote Network Equipment
The switching process takes place automatically. Connected devices can exchange network traffic without requiring manual routing or advanced switch configuration.
This architecture makes the 1783-US8TG2GX suitable for industrial applications that combine local Gigabit Ethernet communication with optional fiber network expansion.

Installation and Maintenance
- Verify the switch model: Confirm that 1783-US8TG2GX is the required Stratix 2000 Gigabit unmanaged switch with eight copper Ethernet connections and two Gigabit SFP slots.
- Select the installation location: Choose a suitable position inside the industrial control cabinet with adequate ventilation and convenient access for maintenance.
- Check mounting arrangements: Ensure that the DIN rail and mounting hardware are suitable for the switch installation.
- Verify power requirements: Check the equipment nameplate and applicable installation documentation before connecting the power supply.
- Inspect copper interfaces: Examine the RJ45 connections for damaged contacts, contamination, or loose cable connections.
- Check combo port assignments: Identify the two shared copper/SFP interfaces before connecting network equipment to avoid treating them as independent simultaneous connections.
- Verify SFP compatibility: Select Gigabit Ethernet SFP modules compatible with the switch and the intended optical network.
- Inspect fiber connections: Check installed SFP modules, optical connectors, and fiber cables for contamination or physical damage.
- Connect network equipment: Use appropriate Ethernet cables to connect PLCs, HMIs, industrial computers, and other compatible devices.
- Verify link indicators: Check the port status LEDs to confirm that copper and installed SFP connections establish the expected network links.
- Monitor network communication: Test data exchange between connected devices and investigate unexpected link interruptions or communication errors.

Technical FAQs
How many independent copper connections are available on the 1783-US8TG2GX?
The switch has eight Gigabit Ethernet copper interfaces, including two combo interfaces shared with the SFP slots. When an SFP module is used in a combo interface, its corresponding RJ45 connection cannot be counted as an independent additional connection.
Are Gigabit SFP modules included with the 1783-US8TG2GX?
No. The two Gigabit Ethernet SFP slots require separately ordered compatible SFP modules. The appropriate optical modules should be selected according to the fiber type, transmission distance, and connector requirements of the network.
Can the 1783-US8TG2GX connect directly to a Fast Ethernet PLC?
Yes. Its Gigabit RJ45 interfaces support 10/100/1000 Mbps Ethernet communication and can connect to compatible 10/100 Mbps PLC interfaces through automatic speed negotiation.
What should be considered when selecting SFP modules for this switch?
The SFP module must support Gigabit Ethernet and be compatible with the switch. Selection should also account for single-mode or multimode fiber, optical wavelength, connector type, and required transmission distance. The selected module must match the specifications of the remote optical interface.
