P146 / Ethernet and PoE / Guide

An injector has two different sides

A documented model, port role, rate or budget is not a verified physical connection.

The useful distinction

Read the exact model and port labels; do not infer network or power capabilities from the modular outline.

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

Follow the documented data input and powered output instead of treating an injector as an interchangeable coupler. [C146A]

An inserted injector has its own Ethernet interface evidence. The captured TL-POE160S rates are 10/100/1000 Mbps. Two 2.5 Gbps endpoints do not establish 2.5 Gbps across that documented path. The worksheet compares the upstream and downstream segments and the shared end-to-end captured rates separately. [C146B]

Before you connect

What to check

  1. Select data input and power output deliberately.
  2. Include injector rates in the data comparison.
  3. Keep power topology separate from data flow.
Trace a supported connection class →

Check the power path separately

The power source for the modeled downstream device is the injector output, not the upstream data endpoint. A selected upstream PSE or PD port is outside this simple documented topology; the tool does not silently chain power equipment.

Respect the boundary

No mains work, passive power, splitter design, pin assignment, surge protection, outdoor installation or hardware safety approval is provided. The source report is a documentation checklist, not instructions to energize an unknown device.
