Feature code C4GB (option 4XC7A95696) is the ThinkSystem Broadcom 57412 10GBase-T 4-Port OCP Ethernet Adapter, Broadcom part BCM957412-N410TL00. It is an OCP 3.0 card with four RJ45 ports that run 10GBASE-T or 1000BASE-T, and a mix of the two speeds on one adapter is supported. The host interface is PCIe 3.0 x8.
The OCP version supports NC-SI, so the server's service processor can share a port for management traffic. Lenovo lists SR-IOV with up to 128 virtual functions. Cable limits at 10GBASE-T are 100 m on Category 6a and 55 m on Category 6; at 1000BASE-T, 100 m on Category 5e or better.
Its PCIe twin is 4XC7A95697 (feature C4GC, Broadcom BCM957412-P410TL00). Lenovo notes that installing the 4-port adapter as a field upgrade requires turning on slot bifurcation (x4x4x4x4) in UEFI for its slot; the flyer shipped with the adapter has the steps. For two 10GBASE-T ports instead of four, Lenovo's Broadcom 57416 OCP adapter 4XC7A08236 is the alternative.
Lenovo lists this OCP adapter for the SR630 V3, SR650 V3, SR635 V3, SR655 V3, SR645 V3, SR665 V3, SR850 V3, SR860 V3, SR675 V3 and SE455 V3, and for the V4 SR630 V4, SR650 V4 and SR650a V4. Confirm the server has a free OCP 3.0 slot and plan the UEFI bifurcation step for a field install.
