Lenovo lists 4XC7A08245 as the ThinkSystem Broadcom 57454 10GBASE-T 4-port PCIe Ethernet Adapter, with feature code B5SU for most servers and BFY6 for the SR860 V2 and SR850 V2.
It is based on the four-port Broadcom BCM57454 controller and uses a PCIe 3.0 x8 host interface in a low-profile card. Its four RJ45 ports support 10GBASE-T (IEEE 802.3an) and 1000BASE-T (IEEE 802.3ab).
Lenovo lists jumbo frames up to 9600 bytes, Broadcom TruFlow flow processing, RoCEv2, Data Center Bridging, SR-IOV, and a silicon root of trust for firmware authentication. Boot options are PXE and UEFI, and iSCSI boot works only through server UEFI.
Lenovo lists CAT6 cables for the ports in 0.75m to 3m lengths (green) and 10m and 25m lengths (green, blue and yellow), plus white unjacketed CAT6 28AWG cables from 750mm to 3000mm.
The adapter ships with a full-height (3U) bracket attached and a low-profile (2U) bracket in the box. The OCP 3.0 version, 4XC7A08240 (B5T4), uses a PCIe 3.0 x16 host interface.
Another 10GBASE-T PCIe adapter in the Lenovo interface card category is the Lenovo ThinkSystem Intel X710-T4L 10GBASE-T 4-port PCIe Ethernet Adapter.
