Lenovo 4XH7A87509 SR650 V3 Middle 4X2.5INC Sas/sata BP KIT

Lenovo 4XH7A87509 SR650 V3 Middle 4x2.5-Inch SAS/SATA Backplane Kit

Overview

The Lenovo 4XH7A87509 is a middle drive backplane kit designed to expand internal storage capacity on the ThinkSystem SR650 V3 server. This kit adds four 2.5-inch SAS/SATA drive bays in the middle bay position, giving you a direct path to increasing on-server storage without reconfiguring your primary front bay layout — relevant when your workload is growing and you need additional spindles or SSDs without adding a separate storage appliance.

Compatibility

The 4XH7A87509 is designed specifically for the Lenovo ThinkSystem SR650 V3 server platform. It is not interchangeable with SR650 V2, SR630, or other ThinkSystem 1U/2U variants — verify your exact chassis generation before ordering. The backplane supports both SAS and SATA drive protocols, so you can populate the four 2.5-inch bays with SAS hard drives, SATA hard drives, or SATA SSDs depending on your storage controller and performance requirements. Confirm that your installed RAID adapter supports the additional backplane connection before deploying — some base configurations require an additional SAS cable or expander to reach the middle bay position.

Installation Notes

Installation is a tool-assisted internal chassis operation. The SR650 V3 must be powered down and removed from the rack before accessing the middle bay area. Ensure your storage controller has an available SAS/SATA port or expander connection to drive the additional backplane. Consult the Lenovo SR650 V3 server hardware maintenance guide for torque specifications and cable routing constraints specific to the middle bay assembly. Weight of the kit is 10.00 lb — account for this when planning rail and rack load calculations, particularly in high-density server rack deployments.
