HPE Ethernet 10/25Gb 2-Port 631FLR-SFP28 Adapter

Power up your data center with the HPE Ethernet 10/25Gb 2-Port 631FLR-SFP28 Adapter, a high-performance dual-port network solution designed to deliver exceptional bandwidth, flexibility, and reliability. This adapter gives you the capability to run each port at either 10G (SFP+) or 25G (SFP28) speeds, enabling a seamless transition from legacy 10 Gigabit networks to modern, high-throughput 25 Gigabit Ethernet. Built for the demands of today’s virtualization, databases, cloud workloads, and data-intensive applications, the 631FLR-SFP28 helps you scale network bandwidth while simplifying maintenance and management. Whether you’re consolidating workloads, upgrading an aging server, or deploying a scalable hyper-converged infrastructure, this adapter provides a versatile, future-proof path to higher performance with reduced total cost of ownership.

• Flexible 10/25Gb performance on a dual-port: Each of the two ports can operate at 10Gbps using SFP+ transceivers or at 25Gbps with SFP28 transceivers, allowing you to tailor network bandwidth to your workloads and connect to both legacy and next-generation switches with a single card.
• Dual-port scalability for dense deployments: With two high-speed ports, the 631FLR-SFP28 enables link aggregation, multi-path networking, or per-VM segmentation in virtualized environments, helping to maximize throughput and reduce bottlenecks across servers and data fabrics.
• Broad server compatibility and easy integration: Designed to fit in standard server chassis and optimized for HPE ProLiant systems, this low-profile PCIe adapter integrates smoothly with existing infrastructures and management tools, simplifying deployment and ongoing maintenance.
• Low-profile, space-saving design for data centers: The compact, low-profile form factor fits a wide range of rackmount and blade servers, delivering high performance without compromising chassis space or airflow—an ideal choice for dense, modern data centers and edge deployments.
• Reliability and lifecycle support: Built on HPE engineering, the 631FLR-SFP28 provides robust reliability, with ongoing firmware updates and compatibility across HPE management ecosystems, making it a durable foundation for evolving networks and workloads.

how to install HPE Ethernet 10/25Gb 2-Port 631FLR-SFP28 Adapter

• Power down the server, unplug from power, and discharge static electricity before handling components.
• Remove the server cover and locate a suitable PCIe slot (preferably PCIe x8 or higher) that accommodates a low-profile card.
• Insert the 631FLR-SFP28 adapter firmly into the PCIe slot and secure the bracket with the mounting screw to the chassis.
• Install your chosen SFP+ and/or SFP28 transceivers into the two ports, then connect the corresponding fiber optic or copper cables as required by your network design.
• Reassemble the server, power up, and install the latest drivers and firmware from HPE or the operating system vendor. Validate the card appears in the system’s device manager or network configuration utility and confirm link status with the management tools or OS utilities.

Frequently asked questions

• Q: Can this adapter operate at both 10G and 25G speeds? A: Yes. Each port can function at either 10Gbps (using SFP+ transceivers) or 25Gbps (using SFP28 transceivers), enabling flexible deployments across evolving networks.
• Q: Do I need to purchase transceivers separately? A: Yes. SFP+ and SFP28 transceivers are required to achieve the desired speeds, and fiber or DAC cables must be selected to match the transceivers and network design.
• Q: Is the card compatible with all servers? A: The 631FLR-SFP28 is designed for HPE ProLiant servers and other PCIe-enabled systems with a compatible low-profile slot; always verify model compatibility and firmware requirements before purchase.
• Q: What operating systems are supported? A: The adapter utilizes standard drivers and is supported by major operating systems; consult the latest HPE driver support matrix for your specific OS version to ensure full functionality.
• Q: Can I use NIC teaming or link aggregation with this card? A: Absolutely. The dual-port adapter supports common networking configurations such as NIC teaming and link aggregation when paired with appropriate switches and drivers, enabling higher aggregate throughput and fault tolerance.
