Lenovo SR670 PCIE 6PIN PCIE 8PIN CBL - 4Z57A26300

Lenovo 4Z57A26300 PCIe 6-pin to 8-pin Cable

Overview

The Lenovo 4Z57A26300 is a PCIe 6-pin to 8-pin adapter cable designed to provide the necessary power connection for specific PCIe expansion cards within compatible Lenovo server systems. This cable is essential for ensuring that components requiring an 8-pin power connector receive adequate and stable power from a 6-pin source, preventing operational issues or system failures. It is intended for integration into rackmount server environments where power delivery must meet precise specifications.

Compatibility

This cable is specifically designed for use with Lenovo server models that utilize a PCIe 6-pin power output and require an 8-pin connection for a PCIe component. While the source document details the Lenovo SR670 server's specifications, including its 2U rack form factor, 24 DIMM sockets, and 2000W power supplies, this cable's precise compatibility is tied to the internal power distribution and PCIe slot requirements of specific Lenovo server generations. It is not a universal adapter and should only be used when explicitly specified by Lenovo for a particular configuration.

Installation Notes

Proper installation requires connecting the 6-pin end to the designated PCIe power output on the server's motherboard or power distribution board, and the 8-pin end to the power input on the compatible PCIe adapter card. Ensure the cable is fully seated at both ends to guarantee a secure connection. This cable is not intended for use with non-Lenovo hardware. The server itself requires 200-240 V AC power input, and its power supplies are 80 PLUS Platinum certified, indicating high efficiency.
