Your option #2 may kill the Ethernet signal unless the beads are 4 or more terminal common mode ones.

Lose communication in the test range 20-80MHz (10Vrms 80% AM). Possible actions: 1. Snap on ferrite inside the EUT (do not want this action) 2. The RJ45 connector on the EUT has a little PCB and ferrite beads can be mounted by cutting the traces and place the beads onto each lines. Anybody who has a positive experience, eliminate immunity failures on Ethernet by introducing ferrite beads? … or is a Common Mode Choke Array more recommended?
