How to install Lenovo ServeRAID M5120 SAS/SATA Controller

• Power down the server, unplug from power, and remove the chassis cover to access the PCIe expansion area.
• Identify an available PCIe x8 (or higher) slot and ensure adequate clearance for the M5120 card and any accompanying cache or energy-pack modules included in your kit.
• Install the M5120 into the chosen PCIe slot, seating the card firmly until it is fully seated and secured with a screw or retention mechanism as required by the chassis.
• If your kit includes cache modules or an energy pack, install them according to the included instructions, and connect any required cables to the backplane or drives as specified for the configuration.
• Power on the server and enter the boot sequence. Open Lenovo ServeRAID Manager (or the server’s BIOS/POST utility if required) to initialize the controller, recognize attached drives, and create initial logical drives (RAID sets) with appropriate redundancy.
• Configure logical drives, set hot-spare policies, assign monitoring thresholds, and apply the latest firmware and drivers from Lenovo’s support portal to ensure optimal performance and security.
