NVIDIA ConnectX-4 Lx EN 25GbE 2-Port SFP28 PCIe 3.0 x8 Adapter, UEFI Boot
MCX4121A-ACUT · Refurbished · 1 year warranty
Quantity (units)
Overview
UEFI boot is what the U in this MPN stands for. The NVIDIA MCX4121A-ACUT shares the hardware outline of other dual-port ConnectX-4 Lx cards: two SFP28 ports at 25GbE and a PCIe Gen3 x8 interface. The title lists UEFI Boot as the extra feature.
If your servers PXE boot over UEFI, or your firmware policy requires it, this is the number to look for. A card without the UEFI label may still work in the same slot, but only the full MPN tells you which build you are ordering. Keep it on the purchase order.
Cabling follows the SFP28 form factor: SFP28 optics or direct attach cables, and a switch running 25GbE. The x8 connector is accepted by most server slots.
NVIDIA's alternative part number 900-9X4B0-0053-ST0 is recorded for this model. It is offered as refurbished or used. Refurbished cards have a warranty choice of 1 year or 3 years, and used cards 90 days. When you request pricing, include your quantity and the server platform it will go into.
