Install EdgeRouter X firmware to EdgeRouter X SFP

3V3 should be 3.3 too ?

Let me say once again all what i'm doing
Maybe I do it wrong
GND to GND
RXD to TX
TXD to RXD

Baud rate 115200
Data Bits 8
Stop Bits 1
Flow Control None

In case all it's okay I will give the router to a random service center

Baud rate is wrong.
Its 115200
