Lenovo 7Z57A03558 3M 25G SFP28 DAC Cable

Overview

The Lenovo 7Z57A03558 is a 3-meter direct-attach copper (DAC) cable designed for high-speed network connectivity within Lenovo ThinkSystem servers. This cable facilitates a direct, passive connection between SFP28 ports, eliminating the need for transceivers and reducing power consumption and latency. It is ideal for server-to-server or server-to-switch connections in rack environments where short-distance, high-bandwidth links are required, such as for storage area networks or high-performance computing clusters.

Compatibility

This 7Z57A03558 cable is specifically designed for use with Lenovo ThinkSystem servers and adapters featuring SFP28 ports. It is compatible with adapters like the ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port PCIe Ethernet Adapter V2 (4XC7A08316) and other Lenovo network adapters and switches that support 25GbE SFP28 interfaces. Ensure your network adapter or switch port is rated for 25Gbps SFP28 connectivity.

Installation Notes

This is a passive DAC cable, meaning it requires no external power. Connectors should be firmly seated into the SFP28 ports on both the server adapter and the receiving device. The cable is rated for a 3-meter length, ensuring signal integrity for short-reach applications. While no specific torque specifications are provided, ensure a secure physical connection. The cable is intended for use within a controlled rack environment.
