Dense machine-side Ethernet aggregation is the role of Allen-Bradley 1783-USP16T in the Stratix 2100 family. It is an unmanaged Layer 2 switch that brings sixteen copper device connections into one industrial cabinet location without introducing managed-switch configuration as part of the operating design.

The product sits at the access layer of a small control network, where controllers, operator devices, drives, remote I/O, and service connections need a fixed copper connection point. Its hardware architecture is intentionally direct: numbered RJ45 interfaces, status indication, and a power connection support local distribution rather than routing or policy control.

Because 1783-USP16T is unmanaged, network behavior is defined by the connected equipment and the wider system rather than a switch-resident feature set. This creates a clear configuration boundary: it provides Layer 2 connectivity for the attached devices, while functions such as routing, managed redundancy policy, and advanced network services belong elsewhere in the architecture.
