Lenovo 4XH7A61124 SR655 2.5 Sas/sata 8-BAY X40 CBL KIT

Lenovo 4XH7A61124 SR655 2.5" SAS/SATA 8-Bay X40 Cable Kit

Overview

The 4XH7A61124 is a factory-matched cable kit designed to wire the 2.5-inch 8-bay SAS/SATA backplane into the ThinkSystem SR655 server chassis via the X40 controller path. If you're expanding storage or replacing damaged internal data cables on an SR655, this is the kit that maintains native backplane-to-controller connectivity — no improvised cabling, no guesswork on connector pitch or signal routing. At 10 lb, this is a substantive multi-cable assembly, not a single replacement lead.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR655 2-socket AMD EPYC rack server platform. The kit targets the 2.5-inch 8-bay SAS/SATA backplane configuration paired with the X40 storage controller. Verify your SR655 backplane variant and controller designation before ordering — the SR655 supports multiple bay configurations and controller options, and Lenovo publishes separate cable kits for each combination. This kit does not apply to SR650, SR630, or other ThinkSystem platforms, nor to the 3.5-inch large-form-factor bay configurations on the SR655 itself.

Installation Notes

Internal server cabling on the SR655 requires depopulating the chassis per Lenovo's hardware maintenance guide — route cables before seating drives to avoid pinch points at the backplane connector. SAS/SATA signal cables are keyed; do not force connector orientation. Confirm X40 controller port assignments match the backplane cable labeling before powering on. No special tooling beyond standard ESD precautions and a #2 Phillips screwdriver is required for the chassis work.
