Description

Lenovo 4XC7A62582 Mellanox CX6 LX 10/25GbE Dual-Port OCP Network Adapter

Overview

The Lenovo 4XC7A62582 is a dual-port 10/25GbE OCP 3.0 network adapter built on the Mellanox ConnectX-6 Lx controller, designed for direct integration into OCP-slot-equipped Lenovo servers. If you're provisioning network adapters for high-throughput server workloads — NVR back-end storage networks, video analytics servers, or east-west data center fabric — this card delivers wire-speed 25GbE per port over SFP28 without consuming a standard PCIe slot. The PCIe 4.0 host interface means the bus itself won't bottleneck aggregate throughput even when both ports run at line rate simultaneously, which matters on dense multi-camera recording platforms pushing sustained write loads. Operating temperature range of 0–55°C covers standard data center and server room environments.

Compatibility

This adapter is designed for Lenovo ThinkSystem servers with OCP 3.0 mezzanine slots — typically the SR630 V2, SR650 V2, SR670 V2, and similar current-generation ThinkSystem platforms that expose an OCP slot on the motherboard. The OCP form factor is not interchangeable with standard PCIe half-height or full-height brackets; verify your server chassis supports OCP 3.0 before ordering. The two SFP28 ports support both 25GbE and 10GbE link speeds, so existing 10GbE SFP+ infrastructure (DAC cables, fiber, switches) remains compatible without replacing optics or cabling. Certifications include CB, cTUVus, CE, FCC, VCCI, ICES, RCM, and RoHS — covering North American and international server deployment requirements. Confirm chassis OCP slot version (3.0 vs. 2.0) before installation, as the two generations are physically incompatible.

Installation Notes

The adapter installs into the server's OCP mezzanine slot — no separate PCIe slot or bracket required. Dimensions are 76 mm wide × 115 mm deep; verify clearance within the chassis before installation, particularly on dense 1U platforms. Operating humidity is rated 0–90% non-condensing, and storage temperature spans -40–70°C, making the card safe for standard warehouse staging environments. Driver and firmware support should be confirmed against the target server's HCL prior to deployment in production environments.
