Broadcom BCM957504-N425G Quad-Port 25 Gb/s SFP28 Ethernet PCI Express 4.0 x16 OCP 3.0 SFF Network Adapter

The Broadcom BCM957504-N425G is a high-performance, quad-port network adapter engineered for modern data centers, hyperscale deployments, and open compute environments. Built to the Open Compute Project (OCP) 3.0 design specification, this compact SFF (small form factor) card delivers 4 independent 25 Gb/s SFP28 network channels in a single PCIe 4.0 x16 slot, providing scalable bandwidth for demanding workloads. Whether you’re consolidating storage networks, fueling virtualized environments, or accelerating server-to-server traffic, the BCM957504-N425G is designed to maximize throughput, minimize latency, and simplify dense server configurations.

• Quad-port 25 Gb/s performance with four SFP28 network connectors, enabling high aggregate bandwidth and flexible topology for data centers and cloud deployments.
• Supports both SFP28/SFP+ optical modules and copper direct-attach cables (DACs), giving you the option to deploy fiber for long-range links or inexpensive copper for short, cost-effective connections.
• PCI Express 4.0 x16 host interface provides substantial headroom for data-intensive workloads while maintaining efficient CPU utilization and low I/O latency.
• Open Compute Project (OCP) 3.0 design specification in a compact, small form factor (SFF) card, ideal for dense rack configurations and streamlined server integration.
• Designed to deliver reliable, flexible Ethernet connectivity across diverse data-center scenarios—from virtualization and clustering to high-performance storage networks—without locking you into a single module ecosystem.

How to Install Broadcom BCM957504-N425G

• Power down your server and disconnect all power sources before beginning installation.
• Open the chassis and locate an available PCIe x16 slot that supports PCIe 4.0/3.0, then remove the slot cover if needed.
• Insert the BCM957504-N425G into the PCIe x16 slot firmly until the retention latch engages securely.
• Secure the card to the chassis with a screw to ensure stable operation and prevent movement during operation.
• Connect your network interfaces using either SFP28/SFP+ optical modules for fiber links or copper direct-attach cables (DACs) for short-range, cost-effective connections. Ensure the transceivers or DACs are compatible with SFP28 ports.
