Lenovo ThinkSystem Mellanox ConnectX-4 Lx 25Gb 2-Port Mezzanine Adapter

Mezzanine cards plug directly onto a server board rather than into an external slot, and the Lenovo ThinkSystem Mellanox ConnectX-4 Lx 25Gb 2-Port Mezzanine Adapter, part number 4XC7A08315, follows that approach. It has two SFP28 ports at 25GbE and a ConnectX-4 Lx controller listed under the NVIDIA name.

The mezzanine form is far more specific than PCIe, because it only fits servers or blade nodes built for it. Check the exact compute node model before ordering. If your platform takes this card, no PCIe slot is used, and the card is typically specified at configuration time.

Two 25GbE ports are enough for redundant uplinks or separate networks. SFP28 optics or direct attach cables, bought separately, connect the ports.

Because mezzanine adapters are tied to a specific node generation, replacing one with the same part number is the safe route. Ask us if you are unsure which number your node uses.

The 4XC7A08315 is offered new, refurbished and used. New and refurbished units carry 1 year or 3 years of warranty, and used units carry 90 days. Send the quantity and node model with your request.
