Lenovo 4XH7A61122 SR655 3.5 Sas/sata 8-BAY X40 CBL KIT

Lenovo 4XH7A61122 SR655 3.5" 8-Bay SAS/SATA X40 Cable Kit

Overview

The 4XH7A61122 is a factory-new cable kit designed to wire the 8-bay 3.5" SAS/SATA drive backplane to the X40 storage controller in Lenovo ThinkSystem SR655 servers. If you're expanding storage in an SR655 chassis or replacing a damaged cable assembly, this kit delivers the correct signal path between backplane and controller without improvising with aftermarket cables that can introduce negotiation failures or intermittent drive errors. Weighing 10 lb, this is a complete cable assembly — not a single cable — suited for full backplane population builds.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR655 1U/2U server platform configured with a 3.5" 8-bay large-form-factor storage backplane and an X40-series SAS/SATA HBA or RAID controller. Both SAS and SATA drive populations are supported, making this cable kit appropriate for hybrid backplane configurations that mix nearline SAS HDDs with SATA SSDs. This kit is not a universal fit — verify your SR655 backplane bay count and controller model against Lenovo's configuration guide before ordering, as the SR655 ships in multiple backplane variants (8-bay LFF, 24-bay SFF, NVMe) that each require a distinct cable assembly.

Installation Notes

Route cables according to the SR655 cable routing guide to avoid contact with cooling airflow paths — improper routing in 1U/2U dense chassis can restrict fan throughput and trigger thermal throttling. Seat SAS/SATA connectors fully until the latch clicks; partial seating is the most common cause of drive-not-found faults post-reassembly. If installing alongside a network infrastructure refresh or integrating the SR655 into a NVR or surveillance storage backend, plan cable dress before populating drives — access becomes restricted once bays are loaded. The UNSPSC code for this kit is 43202105 (computer storage device accessories), confirming its classification as a server storage accessory.
