Lenovo 4X97A80387 SR645 8X2.5" Sas/sata BP Cable Kit V2

Lenovo 4X97A80387 SR645 8x2.5" SAS/SATA Backplane Cable Kit V2

Overview

The Lenovo 4X97A80387 is the V2 backplane cable kit designed for the ThinkSystem SR645 server, enabling connectivity between the storage backplane and the system board for up to eight 2.5" SAS or SATA drives. If you're expanding storage capacity in an SR645 or replacing a damaged cable assembly during a hardware refresh, this is the factory-specified kit to maintain full signal integrity and firmware compatibility across your drive bay configuration. Mixing third-party cables in server backplane paths risks negotiation errors and unsupported RAID controller behavior — 4X97A80387 eliminates that variable.

Compatibility

Designed for the Lenovo ThinkSystem SR645 rack server configured with an 8x2.5" drive bay backplane. Supports both SAS and SATA interface drives, giving you flexibility across spinning-disk and solid-state storage types in that bay. Verify your SR645 chassis revision and backplane assembly against the V2 designation before ordering — earlier SR645 configurations may use a different cable routing or connector layout. This kit is not interchangeable with SR630, SR650, or other ThinkSystem chassis; the backplane connector positions and cable lengths are chassis-specific.

Installation Notes

Route cables per the SR645 server maintenance documentation to avoid pinch points near the fan wall. The 2.10" profile depth of the packaged kit (12.20 x 9.80 x 2.10 in, 1.30 lb) is consistent with the bundled cable harness — confirm adequate clearance before routing in high-density rack configurations with adjacent cable management arms. No special tooling is specified beyond standard server disassembly procedures for the SR645 platform.
