The Lenovo 7ZT7A00545 is a network interface card that equips compatible ThinkSystem servers with four independent 1 Gigabit Ethernet ports through standard RJ45 connectors. By using the Intel Ethernet Connection X722 embedded in the Intel C624 Lewisburg PCH chipset, it offers dependable copper-based connectivity without occupying a traditional PCIe slot.
The card attaches to the server’s onboard LOM connector, a design choice that keeps valuable expansion slots free for storage or accelerator cards. Each port can be assigned to separate traffic types, making it useful for administrators who need dedicated links for production, management, backup, or virtualization networks.
Deployment is straightforward: mount the module, secure it to the motherboard, and plug in existing Cat5e or Cat6 cables. Once installed, the server gains steady 1 GbE throughput well suited to everyday enterprise workloads, branch office infrastructure, and lab environments where predictable network performance and simple cabling are priorities.
With four ports in one compact module and direct integration with the server’s chipset, this card is a practical choice for IT teams looking to expand network capacity while preserving flexibility inside Lenovo ThinkSystem racks.
