4XC7A08238: Lenovo ThinkSystem Broadcom 57414 10/25GbE SFP28 2-Port PCIe Ethernet Adapter

Also listed as: BCM957414A4142CC, 01PE822, B5SS, SP47A49285, 4XC7A08238-01, BCM957414 · made by Broadcom

The Lenovo 4XC7A08238 is an enterprise dual-port 10/25GbE SFP28 network interface card powered by the Broadcom BCM57414 NetXtreme-E controller. Designed for high-throughput enterprise virtualization, software-defined networking (SDN), and private cloud fabrics across ThinkSystem servers, it features TruFlow hardware-assisted packet processing, RoCE v2 (RDMA over Converged Ethernet), and comprehensive hardware offloads including VXLAN, NVGRE, and Geneve overlay tunneling. It supports both 25GbE and 10GbE data rates using SFP28 optical transceivers or direct-attach copper (DAC) cables. Buyers in the used market should verify that authentic Lenovo firmware is installed for seamless integration with UEFI and XClarity.

Specifications

About the 4XC7A08238

4XC7A08238 is Lenovo's dual-port 10/25GbE SFP28 PCI Express 3.0 x8 network adapter based on the Broadcom BCM57414 controller. Designed for cloud hosting, hyperconverged infrastructure, and high-frequency storage networking, it delivers wire-speed RoCEv2 RDMA, TruFlow packet processing acceleration, and hardware network virtualization offloads (VXLAN, NVGRE, GENEVE). It sits in Lenovo's mainstream 25GbE connectivity tier, replacing older 10GbE adapters while offering smooth 10G/25G auto-negotiation.

Compatibility

Supported across Lenovo ThinkSystem rack and tower servers, including SR650, SR650 V2, SR630, SR630 V2, SR665, and ST650 V2. It installs into any standard PCIe 3.0 or 4.0 x8 or x16 slot. Both full-height and low-profile brackets are supported. The adapter requires compatible 25G SFP28 or 10G SFP+ optical transceivers or direct attach copper (DAC) cables. It is not compatible with proprietary OCP 3.0 slots without using the distinct OCP form-factor version (4XC7A08237).

How to identify a genuine unit

A genuine Lenovo PCIe card displays a green PCB with a Lenovo barcode label listing option part number 4XC7A08238, FRU part number 01PE898 or 01PE899, and feature code B5ST. The main heatsink covers the Broadcom BCM57414 silicon. In UEFI setup, XClarity Administrator, and Linux lspci, the card reports Lenovo vendor and subsystem IDs (17AA). Generic Broadcom cards will function in Linux but will not integrate seamlessly with Lenovo XCC firmware updating tools.

Buying used

Inspect the dual SFP28 cages for bent optical transceiver pins or loose metal EMI spring shielding. Check that the card comes with the appropriate PCIe bracket (low-profile for 1U servers or standard full-height for 2U systems). Request confirmation that the card establishes 25G link speed and that firmware can be updated cleanly using Lenovo OneCLI. Check for scorch marks or heat degradation around the passive heatsink assembly.
