Lenovo 4X97A59804 SR650 V2 3.5 Front BP Sas/sata CBL KIT

Lenovo 4X97A59804 SR650 V2 3.5-Inch Front Backplane SAS/SATA Cable Kit

Overview

The Lenovo 4X97A59804 is a factory-new SAS/SATA cable kit designed for the 3.5-inch front backplane configuration of the ThinkSystem SR650 V2 server. When expanding or replacing storage cabling in an SR650 V2 — whether during an initial build-out or a post-deployment drive-bay addition — this kit supplies the correct OEM-matched cabling to maintain signal integrity between the backplane and the system's storage controller. Using non-OEM substitutes risks connector incompatibility and impedance mismatches that degrade SAS link reliability; the 4X97A59804 eliminates that risk by providing cabling validated for this chassis specifically.

Compatibility

Designed exclusively for the Lenovo ThinkSystem SR650 V2 server platform with the 3.5-inch front drive backplane configuration. This kit is not interchangeable with the SR650 (Gen 1), SR630 V2, SR650 V3, or other ThinkSystem platforms — backplane pinouts and cable routing differ across generations and chassis sizes. Confirm your server's machine type and backplane option before ordering. Supports both SAS and SATA drive protocols, so it accommodates mixed HDD/SSD configurations on the same backplane without requiring separate cabling runs.

Installation Notes

Route cables according to the SR650 V2 hardware maintenance guide — cable dressing matters in a dense 2U chassis where airflow obstruction can affect thermal performance across adjacent components. The kit dimensions (11.50 × 9.80 × 2.12 in, 1.35 lb) are consistent with a multi-cable assembly; handle connectors carefully during seating to avoid bent pins on SAS/SATA headers. No additional tools beyond standard server servicing equipment are required, but confirm the system is powered down and energy stored in capacitors is discharged before disconnecting or reconnecting backplane cables.
