Hello, E5-2600 :
Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please tell us if this situation is related to an add-in card? Please give us all the information if it is an add-in card.
Could you please clarify us know if it is your own design? In case that it is your design, could you please let us know the sources that you use to develop it and if it has been reviewed by Intel?
Waiting for your reply to these questions.
Hi Carlos A,
Thanks for your reply.
The LAN chip I210-IS and SFP are located on the mother board, not an add-in card.
The design follows I210 datasheet and I210 dual design guide. Cause I210-IS is not the first time used on our products, so we did't pass it to Intel.
By the way,we have another project which has the same issue, and we have checked the schematic, we suspect the issue maybe related to the EEPROM, so could you please provide us the latest one? I don't know whether the EEPROM we have is correct or not .
Waiting for your reply, thanks.
