Lenovo 4XH7A86755 SR655 V3 8X2.5INC SAS M BP KIT

Lenovo 4XH7A86755 SR655 V3 8x2.5-Inch SAS Backplane Kit

Overview

The Lenovo 4XH7A86755 is an 8-bay, 2.5-inch SAS backplane kit designed for direct installation into the ThinkSystem SR655 V3 server. If you are expanding storage capacity on an SR655 V3 or replacing a failed backplane mid-deployment, this kit provides the SAS interface infrastructure to support up to eight 2.5-inch drives in that specific chassis. Weighing 10 lb and sourced from Mexico (Country of Origin: MX), the 4XH7A86755 ships as a factory-new component classified under UNSPSC 43211600 (IT storage and data media).

Compatibility

This backplane kit is purpose-built for the Lenovo ThinkSystem SR655 V3 platform. It is not a universal fit — confirm your chassis is specifically the SR655 V3 before ordering. The SAS interface aligns with SAS HDD and SSD drives rated for 2.5-inch form factor deployment in that server storage components bay configuration. If your environment runs a different SR655 generation or an alternate ThinkSystem chassis, verify the Lenovo parts compatibility matrix for the correct backplane option; mixing generations can result in physical or electrical incompatibility.

Installation Notes

Installation requires access to the SR655 V3 chassis interior. Follow Lenovo's published SR655 V3 hardware maintenance guide for backplane swap procedures — improper seating of SAS connectors can prevent drive detection at POST. Ensure the server is fully powered down and grounded before handling the backplane. The 10 lb weight reflects the shipped assembly; handle with care to avoid damage to the SAS signal pins prior to installation.
