Lenovo lists 4XC7A08316 (feature code BD49) as the ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port PCIe Ethernet Adapter V2. Lenovo says the V2 improves electrostatic discharge support over the original 4XC7A08241, with no functional change.
The adapter is based on the four-port Broadcom BCM57454 controller with a PCIe 3.0 x16 host interface. Its four SFP28 connectors each take a transceiver, a direct-attach copper cable or an active optical cable.
Lenovo lists PXE boot, jumbo frames up to 9600 bytes, 802.3ad link aggregation, 802.1q VLAN tagging, SR-IOV, Data Center Bridging and RoCEv2, with Broadcom TruFlow flow processing and a silicon root of trust for firmware.
For optics Lenovo lists 4M27A67041 (Lenovo 25Gb SR SFP28, BFH2), 4TC7A69045 (dual-rate 10G/25G SR SFP28 85C, BF10) and 7G17A03537 (dual-rate 10G/25G SR SFP28, AV1B), plus 10Gb SFP+ and 1Gb SFP RJ-45 transceivers.
The box holds the adapter with a full-height (3U) bracket attached and a low-profile (2U) bracket included. The OCP 3.0 version of this family is 4XC7A08242.
