Lenovo 4X97B04178 SR630 V4 E3.S 1T Book 2&3 Cable KIT

Lenovo 4X97B04178 SR630 V4 E3.S 1T Book Cable Kit

Overview

The Lenovo 4X97B04178 is a factory cable kit designed to wire E3.S 1T (1-Terabyte form factor) NVMe drives into Book 2 and Book 3 drive bay positions on the ThinkSystem SR630 V4 rack server. If you are configuring or expanding an SR630 V4 with E3.S storage in the second or third book enclosure, this kit provides the specific signal and power cabling required — without it, those bay positions simply cannot connect to the backplane. Weighing 10 lb, the 4X97B04178 ships factory-new from Lenovo's Mexico manufacturing facility (UNSPSC 26121624).

Compatibility

Designed exclusively for the Lenovo ThinkSystem SR630 V4 platform. Specifically targets Book 2 and Book 3 E3.S 1T bay configurations — not interchangeable with Book 1 or with 2.5-inch/3.5-inch SAS/SATA drive cable kits. Verify your SR630 V4 chassis build-out and backplane option before ordering; Lenovo's SR630 V4 supports multiple storage book configurations and each requires its own matched cable kit. This kit is not compatible with SR630 V3 or earlier SR630 generations, nor with other ThinkSystem platforms such as the SR650 or SR650 V2.

Installation Notes

Installation takes place inside the SR630 V4 chassis. Power down and de-energize the server fully before routing cables — live cable work inside enterprise rack environments risks backplane damage. Route cables per Lenovo's SR630 V4 hardware maintenance guide for Book 2/Book 3 positions; cable routing paths in the V4 chassis are specific to each book slot and incorrect routing can prevent drive recognition. No special tooling beyond standard server hand tools is required, but confirm cable locking tabs are fully seated at both the drive backplane and the system board connectors before powering on.
