      • Before you make changes to disk drives, disk drive controllers, disk drive backplanes, or disk drive cables, back up all important data that is stored on hard disks.

      • Before you remove any component of a RAID array, back up all RAID configuration information.

    5. If one or more NVMe solid-state drives are to be removed, make sure that the drive is shut down via the operating system (see the documentation for your operating system for information and instructions). The drive activity (green) LED is on solid for an NVMe drive that is shut down. See the labels above the drive bays to determine the type of the drive to remove. If the drive bay numbers come with the term “NVMe”, it indicates the installed drives are NVMe solid-state drives.

After you finish
