How to Install Lenovo PM1645

• Power down the server or storage chassis and perform standard electrostatic discharge precautions before handling any internal components.
• Identify an available 3.5-inch SAS drive bay or drive cage that supports hot-swappable enterprise SSDs, compatible with your ThinkSystem or compatible server infrastructure.
• Prepare the PM1645 by ensuring you have the correct drive caddy or sled for your chassis, aligning the SATA/SAS connectors with the backplane interface, and enabling the drive slot to receive the module securely.
• Insert the PM1645 firmly into the drive bay, ensuring the connector engages completely with the backplane. Secure the drive with the appropriate screws or retention mechanism provided by the chassis or caddy.
• Reconnect SAS cables (and power if required) to the backplane, power up the system, and enter the server’s RAID or storage controller BIOS/UEFI interface to recognize and initialize the new drive.
• In the operating system, initialize and format the volume as needed, and configure any required RAID arrays, hot-spares, or tiering policies to maximize performance and reliability for your workloads.
