Lightning Strike Broken WAN Port

The SFP port has probably better

galvanic isolation. Better chance to survive some sommer storms

Probably only two ways to find out:

• test/check the board circuits with proper equipment (voltmeter | multimeter | oscilloscope)
• get an SFP module

There’s a good chance your SFP is OK since high voltage typically fries just the transformer or circuitry around the ethernet port.

That is lucky and could vary with the power/interval of the surge. If the PCA9538 microcontroller got fried too it would be goodbye for the SFP as well.

@carwyn

how this shared port is wired up internally
