- 5 个网口都用芯片内置的 PHY，MDI 从芯片直连变压器，中间没有其他器件。 - 变压器芯片侧的中心抽头各接 0.1 µF 到地，另外预留一个 0 Ω 到 +3V3A 的位置（默认不贴）。 - 线缆侧中心抽头各经 75 Ω 汇到一点，再经 1 nF / 2 kV 接屏蔽地 CHASSIS（Bob Smith 终端）。CHASSIS 与 GND 之间有一颗 1 nF 电容。 - 每对差分线旁预留了 ESD 保护（TPD4E02B04，默认不贴）。
1. 安装 KiCad 10.0 或更新版本。 2. 打开 rtl8367-switch.kicadpro。RTL8367RB、H5007NL 和 RJ45 的符号与封装在 lib/ 里，工程的库表已经指向它们；其余来自 KiCad 官方库。 3. 3D 模型（可选）：有 6 种器件的 3D 模型不在 KiCad 官方库里，版权也不允许随仓库再分发。按 3dmodels/README.md 下载到 3dmodels/，3D 查看器（Alt+3`）里就能看到完整外观。不下载也不影响原理图、PCB 和生产文件。
