I've been scratching my head thinking about this one. Are you saying you had C6100 sleds that worked perfectly, then you swapped something (what?) out, and now the existing sleds' NIC2 doesn't work? Or are you saying new C6100 sleds don't come with NIC2 working?
From memory, there are 2 host-side NICs; one or more of these can act in a "shared" NIC mode for reduced cabling requirements, and a dedicated BMC-only NIC. I've never seen the shared mode prevent operation from host side. Are these NICs chips on the main planar or is there a separate attachment NIC board that is attached in that provides these? In general the answer here is tough because the functionality you're asking about should "just work" and the only way I can imagine it ever not... involve really exotic scenarios. You might try booting Linux, see what the kernel detects in dmesg, and also look through lspci to see if the NIC devices are there. Actually, wait. That might be it.. how many CPUs do you have? I don't have the schematic in front of me, but typically these are sold as 2 CPU sleds. If the second NIC is hung off the second CPU's PCIe for performance optimization reasons, missing CPU --> no PCIe root port --> no NIC2.

I have even been contemplating building a custom on/off/reset button feature as the board has the pins there to handle that, and even the LED's for activity and power. My little environment has these guys, plus some r905, and 2-3 C6100 XS23-TY3 enclosures all running proxmox 5.2, and they really do the job just fine. A while back I purchased an enclosure with no memory/processors/hard drives to use as spare parts, and last weekend I had to actually replace one of my boards. Everything went smoothly, and it didn't take me long to swap it out. Got everything back together and it worked like a champ, or so I thought. Like I said, everything works great except for one tiny, somewhat significant problem: NIC1 works NIC2 does not. In bios NIC1 shows up with the MAC address, but NIC2 shows no MAC address. Bad board, right? So I tried out a second board... Same issue. Then, a third... Same issue. So here is my question, what in the heck am I missing here. I cannot believe that all three of these boards have a bad NIC2. Has anyone else run into this issue? - J -
