Lenovo 4X97B05994 Thinksystem 1U/2U V4 NVIDIA CONNECTX-8 AUX Cable KIT

Lenovo 4X97B05994 ThinkSystem ConnectX-8 AUX Cable Kit

Overview

The 4X97B05994 is a factory-new auxiliary cable kit designed for NVIDIA ConnectX-8 network adapters installed in Lenovo ThinkSystem 1U and 2U V4 rack servers. This kit supplies the AUX interconnect cabling required to complete ConnectX-8 adapter deployments — without it, the adapter cannot establish the auxiliary signaling path the system expects, leaving the slot non-functional. If you are commissioning or expanding a Lenovo ThinkSystem V4 server with ConnectX-8 high-speed networking, this cable kit is a required installation component, not an optional add-on. The kit ships at 1.00 lb, consistent with a small-form cable assembly.

Compatibility

Designed specifically for Lenovo ThinkSystem V4-generation rack servers in 1U and 2U form factors paired with NVIDIA ConnectX-8 adapters. The V4 designation is load-bearing here — ConnectX-8 AUX cable routing and connector positions differ between server generations, and using this kit in non-V4 ThinkSystem chassis is not supported by the evidence. Verify your server generation and adapter part number against Lenovo's compatibility matrix before ordering. The UNSPSC code 26121620 classifies this as a power and signal cable assembly within the data center infrastructure category.
