M.2 Cable Kit Lenovo 4X97A80440 for ThinkSystem SR650 V2 / SR665

The M.2 Cable Kit Lenovo 4X97A80440 for ThinkSystem SR650 V2 / SR665 supplies the cabling and connector components required to mount and connect M.2 NVMe or SATA drives in compatible ThinkSystem SR650 V2 and SR665 server chassis. It enables installation of an M.2 device as a system boot drive or additional local storage, integrating with the server's motherboard and drive bay layout to provide reliable data and power connections for compact, high-performance storage modules.

Advantages

This M.2 cable kit is engineered to match Lenovo ThinkSystem mechanical and electrical requirements, ensuring correct fit and signal integrity for PCIe NVMe and SATA M.2 modules in supported server platforms. It reduces installation complexity by providing pre-formed cables and connectors designed for the server chassis, minimizing cable routing conflicts and improving airflow. The kit supports use as an OS boot device or for local storage expansion, enabling faster boot times and lower latency compared with traditional disk drives when used with NVMe modules.

Suitable for

• Installing M.2 NVMe or SATA drives in ThinkSystem SR650 V2 servers
• Installing M.2 NVMe or SATA drives in ThinkSystem SR665 servers
• Configuring an M.2 module as a system boot drive
• Expanding local storage capacity or adding low-latency drives for caching

Key specifications

• Compatibility: Designed for Lenovo ThinkSystem SR650 V2 and SR665 server chassis
• Supported drive types: M.2 NVMe (PCIe) and M.2 SATA modules
• Cable type: Server-grade internal M.2 data and power cabling with matched connectors
• Form factor: M.2 support for standard single-sided and double-sided modules depending on server tray clearance
• Installation: Includes pre-formed routing to fit server chassis layout and mounting points

How to use

Power down the server and follow standard electrostatic discharge (ESD) precautions before beginning installation. Open the server chassis according to the ThinkSystem SR650 V2 or SR665 service manual and locate the M.2 installation area or designated connector on the motherboard/backplane. Position the M.2 module in the provided bracket or slot, secure it per the chassis instructions, and connect the M.2 cable kit connectors to the module and to the corresponding motherboard or backplane headers. Verify all connections are seated and route cables to avoid obstructing airflow or other components. Close the chassis, power on the system, and confirm the server BIOS/UEFI recognizes the installed M.2 device before installing an operating system or configuring storage.

Recommendations

Use firmware and BIOS versions recommended by Lenovo for the ThinkSystem SR650 V2 and SR665 when adding M.2 drives. Select M.2 modules of appropriate length and thermal profile for the server environment, and ensure proper airflow and thermal monitoring for sustained high-performance NVMe usage.
