Port mapping for R2401 on a dell VRTX

Hey,

Not sure I'm in the correct location to post this but I hope I do.

So we have a Dell VRTX server that has an internal R2401 NIC. I'm trying to understand how to external physical ports connect to the internal ones. I went over the documentation but It doesn't seem to point me in the right direction, it just explains how the ports are grouped, but not exactly how to the external-to-internal mapping works.

Would really appreciate some help
