    how to disable i350 dual/quad port?

    JeroenK Community Member

      Howdy, we have a project an intel X520 OCP card installed and as such we would like to disable the onboard/embedded i350 dual or quad port NICs (so that they are disabled at the PCI level so they don't show up in the BIOS). We could disable a single port (LAN0) from the x520 using as example: eeupdate /nic=1 /ww=0x192 2

      However can we do the same for both or all 4 ports of the i350? I'm aware that you can't disable LAN0 from the i350; but maybe you could have it disabled at a PCI level but still keep the management function open? Would somebody has any guidance on this request using the eeupdate tool?

      Thanks, Jeroen

          Hello JeroenK,

           

          There was a technical issue, we were able to see your post until today. We're sorry.

           

          Could please tell us the platform and the OS you're using?

           

          We'll continue working in your case, and waiting for your update.

           

          Best regards,

           

          Jimmy.

            Hello JeroenK,

             

            We have received feedback from our engineers.

             

            Please refer to section 3.7.8.5.7 Internal PHY Power-Down State in the Intel® Ethernet Controller I350 Datasheet, and also section 6.2.21 Software Defined Pins Control (LAN Base Address + Offset 0x20).

             

            The following register values:

             

            0x0c0c ->  disables PCI + management.

            0x040c ->  disables PCI, management may still operate.


            In terms of eeupdate:

             

            Disable port 0 : eeupdate /nic=1 /ww=0x20 0x040c

            Disable port 1 : eeupdate /nic=1 /ww=0xa0 0x0c0c

            Disable port 2 : eeupdate /nic=1 /ww=0xe0 0x0c0c

            Disable port 3 : eeupdate /nic=1 /ww=0x120 0x0c0c


            You can try it on port 0, but it's doubtful that it'll work.


            According to the datasheet this port can't be disabled to avoid a bricked EEPROM.


            Please let us know your results.


            Best regards,


            Jimmy.
