Lenovo 4X97A59822 SR860 V2 Switch/retimer NVME Cable KIT

Lenovo 4X97A59822 SR860 V2 NVMe Switch/Retimer Cable Kit

Overview

The Lenovo 4X97A59822 is a factory-new NVMe switch/retimer cable kit designed for internal NVMe signal routing in Lenovo server platforms. The retimer function preserves signal integrity over the cable run — critical in dense, high-lane-count NVMe configurations where signal degradation can cause drive enumeration failures or throughput drops. If you are replacing a damaged harness or adding NVMe backplane connectivity in an SR860 V2 build, 4X97A59822 is the genuine Lenovo part for the job.

Compatibility

This cable kit is designed for the Lenovo ThinkSystem SR860 V2 four-socket rack server. It is not a universal NVMe cable — verify the exact chassis generation and backplane configuration before ordering. The SR860 V2 platform supports multiple server accessory configurations depending on drive bay count and PCIe topology; consult the Lenovo SR860 V2 hardware maintenance manual to confirm the correct cable assembly for your specific backplane slot assignment. Do not substitute with SR860 (V1) cables — connector and retimer circuit differences make them incompatible.

Installation Notes

NVMe retimer cables in the SR860 V2 are routed through managed cable channels inside the chassis. Power down and fully discharge the server before handling internal signal cables. Match the cable routing to the labeled backplane headers — reversing NVMe switch cable orientation can prevent drive detection without producing a visible hardware fault. This is an internal component; installation requires removing the top cover and, depending on configuration, the riser cage. Follow ESD precautions throughout.
