How to install Lenovo ThinkSystem SR665 Middle 4x3.5" SAS/SATA Backplane Option Kit

• Power down the server, unplug from power, and ensure you are working in a static-free environment before handling internal components.
• Remove the server side panel and gain access to the mid-backplane area where the four 3.5" drive bays reside, taking note of existing drive path routing and connector locations.
• If replacing an existing backplane, carefully disconnect SAS/SATA cables and document routing to ensure correct reattachment to the new backplane and storage controller connections.
• Align the backplane with the chassis mid-plane and slide it into place, ensuring connector engagement with the mid-plane and backplane interfaces. Verify that mounting points align with the chassis standoffs.
• Secure the backplane using the supplied screws or mounting hardware, then reconnect the SAS/SATA cables from the backplane to the storage controller or interconnect module. Reinstall drive carriers, reattach the side panel, and restore power to the server. After boot, confirm that all four drives appear in the BIOS/RAID controller utility and operating system storage manager.
