Dell Broadcom 57414 2-Port 25GbE SFP28 OCP 3.0 Network Card — NHN45

This is a dual-port 25GbE SFP28 OCP 3.0 network card using the Broadcom 57414 chipset, carrying Dell part number NHN45.

For short links inside a rack, direct-attach cables are simpler than optics. Separate ports can carry separate networks (management, storage and production), or be teamed for resilience and bandwidth. The OCP 3.0 format uses its own bay at the rear of the server, so PCIe slots stay free. SFP ports take optical transceivers or direct-attach copper cables for links to top-of-rack switches. Check driver support for your operating system and hypervisor version before fitting. Look-alike parts can differ in revision, and the Dell part number is what tells them apart. VLAN tagging lets one physical port carry several logical networks. As a Dell part it is intended for PowerEdge servers with the matching slot; confirm the part number against your system. Use the part number NHN45 to confirm the card matches the one already in your system.

Our Johannesburg team inspects and bench-tests the part before it is released as certified refurbished.
