X1 Carbon gen7, which Thunderbolt 3 dock uses "Net ext for Eth/side mechanical docking" port?

2020-10-11, 16:05 PM

I'm mostly happy with my gen 7 X1 Carbon (type 20R1) but am having trouble finding a Thunderbolt 3 docking station that utilizes the Carbon's "Network extension for Ethernet/side mechanical docking" port as referenced at https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-x1/X1-Carbon-Gen-7/p/20R1001TUS     See attached image of the port I want the dock to connect to.   


40AC0135US or 40AN0135US would suit my needs except that they appear to use only the USB-C connection, which I feel is not physically robust enough to not have a premature failure.  If I can't find a dock that comes with the combo cable, can I just order one separately?   It would look similar to 03x7540, but that one appears to not have the right connection on the X1 side.  


Thanks for your help!

That port is intended to be used by side docks, not a combo cable AFAIK.


40AG, 40AH, and 40AJ.
