Lenovo 4XC7A62580 Mellanox ConnectX-6 Lx Dual-Port 10/25GbE PCIe Adapter

Overview

The Lenovo 4XC7A62580 is a dual-port 10/25GbE PCIe network adapter built on the Mellanox ConnectX-6 Lx chipset. It installs internally into a server or workstation PCIe slot, adding two SFP-based fiber uplinks where onboard NICs fall short of throughput or port density requirements. The practical use case is straightforward: high-bandwidth server connectivity for storage traffic, VM clustering, or network segmentation in rack-based deployments where 1GbE is a bottleneck and the existing chassis lacks integrated 25G capability. Part number 4XC7A62580 is sourced factory-new through TD Synnex distribution.

Compatibility

Designed as a component for Lenovo ThinkSystem server and workstation platforms that support standard PCIe expansion. The card uses an SFP fiber optic connector on each of its two ports, so it pairs with SFP+ (10G) or SFP28 (25G) transceivers and direct-attach cables depending on target link speed — confirm transceiver compatibility with the switch fabric before ordering. Suitable for integration into PCIe network adapter slots in rack servers where dual-port fiber connectivity is required. Certifications cover CB, cTUVus, CE, FCC, VCCI, ICES, RCM, and RoHS, making it deployable across North American, European, and Asia-Pacific regulated environments without additional compliance review.

Installation Notes

The card measures 96 mm wide × 69 mm tall — verify available slot height (full-height vs. low-profile bracket) before installation. Operating temperature range is 0–55°C; storage down to -40°C. Relative humidity tolerance runs 0–90% non-condensing during operation. Weight is 0.50 lb. No antenna is present — this is a wired-only adapter. Ensure the host PCIe slot version and lane width are confirmed against the ConnectX-6 Lx requirements prior to seating the card, as underpowered slots will limit achievable throughput.
