ConnectX-4 Lx Dual-Port 25GbE Daughter Card

This ConnectX-4 Lx adapter is a dual-port 25GbE network daughter card built for Dell 13th and 14th generation servers. It fits the Dell 0R887V slot and carries the CX4121C identifier for precise compatibility matching. The card adds two high-speed Ethernet connections through a single mezzanine form factor.

For Dell 13G and 14G server upgrades

This card suits administrators adding 25GbE connectivity to compatible Dell PowerEdge systems that accept the 0R887V daughter card. It is not for servers outside the 13th and 14th generation Dell lineup, nor for standard PCIe slots that require a full-height bracket. Buyers needing a different port count, speed, or form factor should verify their server’s mezzanine specification first.

Questions about this item

Should I pick the 13gen or the 14gen server slot for this ConnectX-4 Lx daughter card?

The card fits Dell 13th and 14th generation servers that accept the 0R887V form factor; verify your chassis slot type before choosing.

What does the 25 GbE rating mean once the card is installed in a server?

Each SFP port negotiates up to 25 Gbps over direct-attach or optical modules, so a single link delivers 25 Gbps throughput.
