Dell Broadcom 57412 Network Daughter Card

The Dell Broadcom 57412 Network Daughter Card is a server-grade adapter built for Dell PowerEdge R640, R740, R740XD, R940 and R540 platforms. It provides dual 10Gb SFP+ and dual 1GbE RJ45 ports through the OCP 2.0 NDC interface. The card targets administrators upgrading 14th Gen servers for hybrid workloads and virtualization.

Dual 10Gb SFP+ and 1GbE RJ45 connectivity

The Broadcom BCM57412 controller drives four ports: two 10Gb SFP+ for high-throughput uplinks and two 1GbE RJ45 for management or legacy links. Advanced offload features such as SR-IOV and VMQ reduce CPU overhead during virtualized workloads. Energy-efficient operation keeps power draw low under sustained traffic.

OCP 2.0 NDC form factor for PowerEdge 14G

The daughter card installs directly into the dedicated NDC slot on compatible PowerEdge 14th Gen chassis, leaving PCIe slots free for other accelerators. Green PCB construction matches Dell server aesthetics and airflow paths. Buyers needing additional port counts or different media types will require a separate adapter.

Questions about this item

Will the NWMNX daughter card fit in the OCP 2.0 slot of my PowerEdge R640 alongside the existing RAID controller?

The NWMNX uses the Dell OCP 2.0 NDC interface, which is the dedicated network slot on the R640, R740, R740XD, R940 and R540; it does not occupy the RAID controller slot.

How can I verify the Broadcom 57412 controller is operating at 10 Gbps on the SFP+ ports after installation?

Check the link speed in the server BIOS, iDRAC or OS network adapter settings; each SFP+ port should report a 10 Gbps connection when a compatible transceiver and cable are linked.

Does the NWMNX package include SFP+ transceivers and RJ45 patch cables, or must I purchase them separately?

The card provides two 10 Gbps SFP+ cages and two 1 Gbps RJ45 jacks; transceivers for the SFP+ ports and copper cables for the RJ45 ports are not included and must be sourced separately.
