VxRail initial Setup - network cabling

Hi all

New bi here

Have 4 x S570 node and 2 x S5224F-ON switches

each S570 node comes with 8 ports ( 2 port NDC, and 3 x PCIe with 2 port each )

What is the correct / best practice way to do network cabling.

Confused about how to connect the 2nd and 3rd PCIe ports.

Would appreciate any help.
