1783-US6T2F Allen-Bradley Stratix 2000 Ethernet Unmanaged Switch

Allen-Bradley 1783-US6T2F Stratix 2000 Unmanaged Switch

The Allen-Bradley 1783-US6T2F, also cataloged as the 1783-US6T2F Unmanaged Switch, operates as a dedicated hardware component for industrial Ethernet layer 2 packet forwarding within Stratix 2000 networking environments. The hardware executes point-to-point data bridging via six 10/100 Mbps copper RJ45 ports and two Small Form-factor Pluggable (SFP) slots configured for fiber optic media insertion. Operating without the need for manual routing tables or software configuration parameters, this component establishes immediate physical layer linkages among programmable logic controllers, human-machine interfaces, and variable frequency drives.

Hardware Specifications

Deterministic Networks and I/O Density Scaling

The Allen-Bradley 1783-US6T2F integrates into EtherNet/IP deterministic networks to secure continuous data throughput across dense I/O topologies. While standard unmanaged architectures do not modify traffic priorities, this module maintains fixed internal backplane bus communication velocity across all eight channels to prevent interface bottlenecks. The physical switching fabric acts as a hardware-level pipeline that sustains the precise synchronization profiles mandated by industrial control layers, executing standard layer 2 frame distribution while complying with broad system firmware flash compatibility targets.

Frequently Asked Questions

Q: Does the 1783-US6T2F require initial IP address assignment or configuration before field installation?

A: No. As an unmanaged switch, the hardware functions strictly via autonomous plug-and-play internal logic, identifying MAC addresses dynamically and routing packets without user software intervention.

Q: What options do the two integrated SFP slots provide for network expansion?

A: The SFP slots accept standard industrial fiber optic transceivers, enabling long-distance data transmission that isolates electrical noise across separate production zones.

Q: How does the dual power input structure protect the network topology against supply failures?

A: The power terminal block accepts either alternating or direct current ranges, allowing the installation technician to wire redundant power lines that prevent network dropping if the primary source trips.

Field Installation Guidelines

• DIN-Rail Mounting Security: Snap the open-style enclosure directly onto standard top-hat DIN rail within the control enclosure. Verify that the grounding spring on the rear panel contacts the bare metallic surface of the rail to ensure frame ground continuity.
• Cable Routing Constraints: Maintain a physical clearance of at least 5 cm between the RJ45 data lines and any adjacent high-power motor or drive cables to minimize electromagnetic interference.
• Power Connection Security: Strip the incoming power conductors according to terminal ratings, insert them into the terminal block, and torque the retention screws down tightly to prevent intermittent connection loss from vibration.
