Allen-Bradley 1783-US6T2F Stratix 2000 Series

The Allen-Bradley 1783-US6T2F, also cataloged as the 1783-US6T2F Unmanaged Switch, serves as the primary 1783-US6T2F Stratix 2000 Series component utilized to execute local network traffic arbitration across EtherNet/IP deterministic networks. The device provides a non-blocking switching fabric to route discrete frame traffic between localized programmable logic controllers (PLCs), human-machine interfaces (HMIs), and variable frequency drives without requiring administrative software configurations.

Hardware Specifications

Industrial Networks & Drive Systems

The hardware structure is optimized to support backplane bus communication velocity data transfer matching the deterministic demands of automated automation cells. Its internal layer 2 forwarding mechanisms maintain EtherNet/IP deterministic networks stability by preserving broadcast storm protection thresholds and managing fixed frame forwarding latencies. The physical network interfaces utilize automated crossover (MDI/MDI-X) negotiation to ensure rapid physical media connectivity without the hazard of manual cabling errors during topology expansion.

Frequently Asked Questions

Q: Does the 1783-US6T2F require explicit configuration files to pass safety protocols such as CIP Safety?

A: No. As an unmanaged layer 2 switch, the device treats CIP Safety packets exactly like standard EtherNet/IP frames, forwarding them strictly via MAC address table mapping without altering the frame headers or data payloads.

Q: What are the restrictions regarding the simultaneous use of AC and DC input power sources?

A: The dual power terminals are designed strictly for single-source redundancy matching the same voltage type. Mixing alternating current (VAC) and direct current (VDC) potentials simultaneously on the power connector assembly will cause internal hardware faults and compromise galvanic isolation borders.

Field Installation Guidelines

1. Snap the 1783-US6T2F enclosure firmly onto standard 35 mm DIN rail profiles, ensuring the grounding spring backing maintains low-impedance electrical contact with the metallic rail surface.
2. Route standard 24 VDC power supply lines through a dedicated industrial circuit breaker to the screw-terminal power plug block.
3. Terminate copper network cables to the six RJ45 ports, confirming that the physical bend radius of each Cat 5e/Cat 6 cable stays within the prescribed wire limitations.
4. Insert certified small form-factor pluggable (SFP) optical transceivers into the dual fiber slots only if multi-node backbone isolation distances are required.
5. Verify that the front-panel diagnostic LED cluster registers green indicators for power inputs and blinking amber/green states for active port communication links.
