Lenovo lists 4XC7A08242 (feature code B5SV) as the ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port OCP Ethernet Adapter. It follows the Open Compute Project NIC 3.0 (version 0.85) design with the primary 4C+ OCP connector, and it uses a PCIe 3.0 x16 host interface.
The controller is the four-port Broadcom BCM57454, and the four SFP28 connectors each take a transceiver, a direct-attach copper cable or an active optical cable. Lenovo lists Wake on LAN for the OCP adapter only, along with the Network Controller Sideband Interface (NC-SI).
Other listed features are PXE boot, function-level reset, SMBus 2.0, jumbo frames up to 9600 bytes, 802.3ad link aggregation and 802.1q VLAN tagging, with TruFlow flow processing, RoCEv2 and a silicon root of trust.
Lenovo's transceiver list for this card runs from 1Gb SFP RJ-45 (00FE333) and 10GBASE-LR SFP+ (00FE331) to the 25Gb parts 4M27A67041 (Lenovo 25Gb SR SFP28, BFH2) and 4TC7A69045 (dual-rate 10G/25G SR SFP28 85C, BF10).
The PCIe versions of this family are 4XC7A08241 and its V2, 4XC7A08316.
