Lenovo 4X97A80395 SR665 2.5 Front BP3 SAS Cable KIT V2

Lenovo 4X97A80395 SR665 2.5" Front Backplane 3 SAS Cable Kit V2

Overview

The Lenovo 4X97A80395 is a SAS cable kit engineered specifically for the ThinkSystem SR665 server, providing the internal cabling required to connect the 2.5" front drive backplane 3 (BP3) to the system's SAS/RAID controller. Installing 4X97A80395 enables the third front drive bay segment — the backplane that sits beyond the standard dual-backplane layout — to communicate with the host adapter, which is the prerequisite for fully populating the SR665's 2.5" drive capacity. Without this kit, BP3 drives go undetected regardless of adapter or drive configuration. Sourced factory-new via channel-direct distribution.

Compatibility

Designed for the Lenovo ThinkSystem SR665 2-socket AMD EPYC rack server. Specifically targets the 2.5" small form factor drive configuration with a third front backplane segment (BP3). Verify your SR665 chassis order code supports the 3-backplane front drive layout before ordering — SR665 configurations with only 1 or 2 active front backplanes do not require this kit. This V2 designation indicates a revised cable routing or connector spec relative to the original; confirm your SR665 build date and chassis revision align with the V2 variant. Not compatible with LFF (3.5") drive configurations or other ThinkSystem models such as the SR650 or SR630.

Installation Notes

Route SAS cables away from airflow obstructions and CPU heatsinks — the SR665 chassis is a high-density 2P EPYC platform where cable management directly affects cooling margin. SAS signal cables are keyed; do not force connectors. Consult the SR665 maintenance manual for the BP3 cable routing diagram specific to your chassis revision before installation. No special tooling beyond standard server drive bay access is required, but a torque screwdriver is recommended when re-securing any backplane fasteners disturbed during routing.
