Lenovo ThinkSystem Mellanox ConnectX-4 Lx 10/25GbE SFP28 2-Port OCP Ethernet Adapter

A ConnectX-4 Lx controller in an OCP 3.0 module is the combination of the Lenovo ThinkSystem Mellanox ConnectX-4 Lx 10/25GbE SFP28 2-Port OCP Ethernet Adapter, part number 4XC7A08246. It has two SFP28 ports rated for 10/25GbE.

This is the earlier ConnectX generation compared with the ConnectX-6 Lx OCP module, so it commonly appears as a replacement part in servers that were specified with it. The controller family is listed under the NVIDIA name, though the title still uses Mellanox.

Before ordering, confirm that the server has an OCP 3.0 slot; this module will not install in a standard PCIe slot. Cabling uses SFP28 modules or direct attach cables bought separately, and the dual-speed ports let the module work on either 10GbE or 25GbE switches.

A two-port layout supports redundant uplinks or separated networks. Like-for-like replacement keeps driver stacks and firmware management unchanged.

Offers cover new, refurbished and used stock. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity and server model for pricing.
