Table
| Severity | Finding | Why it matters |
|---|---|---|
| High | The schematic symbol naming does not match the datasheet pin functions. Pins that the datasheet marks NC are currently exposed as signal terminals, and several center-tap / LED / pair names appear shifted. | This can cause wrong net assignments, bad magnetics hookup, LED miswiring, or complete link failure. |
| High | The project description says -40 to 85 C and 4PPoE 120 W, but the extracted drawing text contains conflicting operating ranges and current data. | Ordering or design decisions based on the current project text may be wrong unless the datasheet property is attached and the exact source is reviewed. |
| Medium | Project property Package or Case Code = TO does not look meaningful for this connector. | Can confuse downstream metadata, filtering, and part selection. |
| Medium | The footprint appears structurally consistent with the drawing: 20 signal/LED holes, 6 shield holes, and 1 NPTH are present, with drill sizes matching the extracted drawing. | Good sign for manufacturability, but the symbol-to-footprint pin mapping still needs correction. |
| Medium | The footprint includes a keepout / grounding-tab region note consistent with the drawing. | If ignored in a real board, copper or traces under the tab area could create assembly or EMC issues. |
