Lenovo ThinkSystem 1Gb 4-Port RJ45 LOM Network Interface Card

Overview

The Lenovo 7ZT7A00545 is a network interface card designed to provide four independent 1 Gigabit Ethernet ports via RJ45 connectors for compatible ThinkSystem servers. It leverages the Intel Ethernet Connection X722 embedded in the Intel C624 Lewisburg PCH chipset to deliver reliable copper-based network connectivity without occupying a PCIe slot. This design helps maintain available expansion slots for other critical hardware while supporting steady 1 GbE throughput suitable for enterprise workloads and branch office environments.

Key features

• Four separate 1 Gigabit Ethernet ports allow dedicated network traffic management for production, backup, management, or virtualization tasks.
• Integration with the Intel C624 PCH chipset ensures stable and efficient network performance directly through the server’s onboard LOM connector.
• Supports standard copper cabling (Cat5e or Cat6), enabling easy integration with existing network infrastructure without additional adapters.
• Installation via the dedicated LOM connector frees up PCIe slots for storage or accelerator cards, maximizing server expansion flexibility.
• Compact module design fits seamlessly into Lenovo ThinkSystem servers, simplifying network upgrades and capacity expansion.

Key specs

• Network ports: 4 x 1 Gigabit Ethernet (RJ45)
• Chipset: Intel Ethernet Connection X722 embedded in Intel C624 Lewisburg PCH
• Cabling type: Copper (Cat5e, Cat6 compatible)
• Interface: Dedicated LOM connector (no PCIe slot required)

Connectivity and compatibility

This network interface card is specifically designed for Lenovo ThinkSystem servers that support the onboard LOM connector. It provides four RJ45 ports for copper Ethernet connections, making it compatible with standard network cables and infrastructure commonly found in enterprise and branch office settings. The card’s direct chipset integration ensures compatibility with server management and virtualization environments that require multiple dedicated network links.

Ideal uses and environments

The Lenovo 7ZT7A00545 fits well in data centers, branch offices, and lab environments where predictable 1 GbE network performance is essential. It is a strong choice for IT teams needing to expand network capacity without sacrificing PCIe slots, especially when managing diverse traffic types such as production, backup, and management networks. Its straightforward installation and compatibility with existing copper cabling make it practical for environments prioritizing simple, reliable connectivity.
