About the 7XC7A05523

The Lenovo 7XC7A05523 is a dual-port 10GbE PCIe network adapter powered by the Intel X710-BM2 controller. Built to address demanding network workloads in virtualization, database clustering, and storage area networking, it delivers full line-rate 10Gbps bidirectional throughput across two SFP+ cages. It includes hardware offloads for VXLAN, NVGRE, and GENEVE network virtualization overlays.

Compatibility

Compatible with Lenovo ThinkSystem SR650, SR630, SR850, SR950, SR650 V2, and SR630 V2 servers. The SFP+ ports accommodate 10G optical transceivers (SR/LR) and direct-attach passive copper (DAC) twinax cables up to 7 meters. It requires appropriate airflow in 1U and 2U chassis to keep the passive heatsink within thermal limits.

How to identify a genuine unit

The adapter displays an official Lenovo parts label reading option code 7XC7A05523, FRU number 01GV568, and feature code B0S2. Two metallic SFP+ optical cages with LED activity indicators are visible on the rear bracket. In Linux environments, it initializes under the standard i40e driver.

Buying used

When purchasing a second-hand X710-DA2 adapter, inspect the optical cage interior contacts for bent EMI fingers or dust contamination. Verify that the NVM firmware is updated to version 8.0 or newer to eliminate legacy firmware bugs. Confirm whether the card includes both full-height and low-profile brackets.
