Lenovo 4XC7A08237 Sieťová karta Interná Optika 25000 Mbit/s

The Lenovo 4XC7A08237 is an internal fiber network card that delivers up to 25 Gb/s network throughput over SFP28 interfaces. Designed for server and workstation installations using a PCI Express host interface, the adapter is available in 1‑port and 2‑port Broadcom-based variants (models 57412 and 57414) and includes both full‑height and low‑profile brackets for compatibility with different chassis. The card supports wired fiber connectivity and comes with documentation.

Advantages

This network card provides high-speed 10/25GbE performance with TruFlow intelligent flow processing and support for advanced networking technologies such as RoCE, SDN, NFV and virtualization. The inclusion of both full‑height (3U) and low‑profile (2U) brackets ensures physical compatibility across a wide range of server form factors, while the PCI Express host interface enables direct, low-latency connection to the system.

Suitable for

• Server and data center network upgrades requiring 10/25GbE fiber connectivity
• Virtualized environments and NFV deployments
• High-performance storage networks and RoCE-enabled applications
• Software-defined networking (SDN) infrastructures

How to use

Install the card into an available PCI Express slot on the host server or workstation, select and attach the appropriate bracket (full‑height or low‑profile) for the chassis, and secure the card. Insert compatible SFP28 transceivers and connect fiber cables to the ports. Install or update the operating system drivers and configure network settings according to your environment and the vendor documentation. For virtualization or SDN use cases, enable relevant features (RoCE, SR‑IOV, etc.) in the host and hypervisor as required.

Recommendations

Use matched SFP28 transceivers and fiber cabling rated for 25 Gb/s, keep firmware and drivers up to date, and verify compatibility with server models and hypervisors before deployment to ensure optimal performance and support for advanced networking features.
