Lenovo ThinkSystem 1Gb 2-Port RJ45 LOM Gigabit Ethernet Network Card

The Lenovo 7ZT7A00544 is a plug-in network adapter that brings two RJ45 connections for 1 Gigabit Ethernet to Lenovo ThinkSystem servers. Built around the Intel Ethernet Connection X722 controller that resides in the C624 chipset, it delivers dependable throughput on both ports while keeping CPU usage low through hardware offload and virtualization support.

This adapter connects through a PCI interface, so installation is straightforward for technicians who manage ThinkSystem rack or tower servers. Once installed, each port can operate at full gigabit speed over standard twisted pair cabling, making it an easy fit for existing data center wiring. The design aligns with Lenovo’s LOM architecture, which means the card integrates cleanly with system firmware and management tools you already use.

Administrators running virtualized workloads will appreciate the virtualization features that help isolate traffic and maintain predictable performance, even when multiple virtual machines share the same physical ports. The offload capabilities handle checksum and segmentation tasks on the adapter itself, freeing host resources for applications and reducing latency.

Whether you are expanding network capacity on a dense virtualization host, adding redundant links for a database server, or simply standardizing on Lenovo components for streamlined support, this dual-port card provides a reliable foundation. Its compatibility with both 1 GbE and 10 GbE environments also makes it a sensible choice for mixed-speed networks in transition.
