About the 4XC7A08295
4XC7A08295 is Lenovo's dual-port 10/25GbE SFP28 network interface card powered by the Intel Ethernet Controller E810-XXVAM2. Operating over a PCIe 4.0 x8 interface, it features Dynamic Device Personalization (DDP), Application Device Queues (ADQ), and concurrent support for both RoCEv2 and iWARP RDMA protocols. It serves as Lenovo's high-performance PCIe Gen4 25GbE adapter for virtualized telco clouds (NFV), storage clustering, and low-latency financial systems, succeeding the older X710 series.
Compatibility
The adapter is certified for ThinkSystem V2 and V3 servers including SR650 V2, SR650 V3, SR630 V2, SR630 V3, SR665, and SR645. It installs into PCIe 4.0 x8 or x16 slots and is backward compatible with PCIe 3.0 slots. It supports SFP28 25GbE optics and DAC cables as well as legacy 10GbE SFP+ modules. It requires current Intel ice drivers under Linux or ESXi. It will not fit OCP 3.0 form-factor mezzanine slots.
How to identify a genuine unit
Genuine Lenovo units feature an Intel E810 PCB with Lenovo printed labels showing option number 4XC7A08295, FRU part number 02JK000 or SP47A08295, and feature code BCD6. The heatsink is clearly branded Intel. In Lenovo XClarity Controller and operating system hardware inventories, the card is identified with Lenovo subsystem IDs and accepts official Lenovo firmware update bundles.
Buying used
Request confirmation of NVM firmware version and verify that both SFP28 ports establish clean link sync under traffic without link flap events. Verify that the card is a standard standup PCIe adapter rather than an OEM custom form factor. Inspect the gold PCIe fingers for wear or surface abrasion. Ensure the bracket matches your server's PCIe riser cage height.
