About the Lenovo ThinkSystem 25GbE Ethernet Adapter 2-Port PCIe Gen 5
This 2-port 25GbE Ethernet adapter delivers 50 Gb/s aggregate throughput per server, making it an essential upgrade for network engineers and infrastructure teams deploying high-performance computing environments. The Lenovo ThinkSystem 25GbE Ethernet Adapter 2-Port PCIe Gen 5 (part number 4XC7A83484) combines dual 25 Gigabit Ethernet ports with next-generation PCIe Gen 5 host interface technology, enabling low-latency, high-bandwidth connectivity for demanding workloads across your data center.
Built on the SFP28 transceiver form factor, this adapter supports Direct-Attach Copper (DAC) cables, Active Optical Cable (AOC), and SFP28 optical transceivers, offering flexible deployment options for both short-reach and long-distance connections. The adapter includes hardware offload capabilities—TCP Segmentation Offload (TSO), Large Receive Offload (LRO), VLAN tagging, and IPv4/IPv6 checksum offload—to reduce CPU overhead and improve throughput efficiency. Available in both low-profile and full-height bracket configurations, the Lenovo adapter integrates seamlessly into Lenovo ThinkSystem Gen 3 and later servers. Full management support is provided through Lenovo XClarity Administrator and Lenovo XClarity Controller, enabling centralized monitoring and configuration across your infrastructure. The adapter is certified for Microsoft Windows Server, Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), and VMware ESXi environments.

Frequently Asked Questions about Lenovo ThinkSystem 25GbE Ethernet Adapter 2-Port PCIe Gen 5
Does the Lenovo ThinkSystem 25GbE Ethernet Adapter 2-Port PCIe Gen 5 support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
