NVIDIA ConnectX-4 Lx EN 25GbE 2-Port SFP28 PCIe 3.0 x8 Adapter

Overview
ConnectX-4 Lx EN cards are a common sight in servers built for 25GbE a few hardware generations ago, and the NVIDIA MCX4121A-ACAT is the two-port version. It has two SFP28 ports at 25GbE and uses a PCIe Gen3 x8 interface.
That makes it a practical replacement for failed adapters in existing hosts. The x8 connector fits a broad range of slots, and the SFP28 ports work with SFP28 optics or direct attach cables. If your switch supports 25GbE, the card needs no other special arrangement.
Check the full MPN against the one in your system. The ConnectX-4 Lx range includes cards with different speeds and a UEFI-boot build that look alike at a glance. This one is listed without a UEFI label.
NVIDIA's code 900-9X4B0-0053-0T1 is recorded as an alternative part number. Offers are refurbished and used. Refurbished units carry 1 year or 3 years of warranty, and used units 90 days. Send the quantity and server model with your request and we will confirm availability and pricing.
