R740xd - 12x3.5 LFF with 4x2.5 SFF - SAS Cable Required

Hi all,

I have a Dell R740xd with a 12x3.5 LFF backplane. I have installed a 4 x 2.5” SFF rear cage but I don’t have the required SAS cable to connect BP1 A0 to my front backplane. Can anyone provide me with the appropriate Dell product code for the correct cable? Is this configuration even supported?

Thanks
