About this task
Attention:
• Read
“Installation Guidelines” on page 55 and “Safety inspection checklist” on page 56 to ensure that you
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 73.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
• Before you remove or make changes to drives, drive controllers (including controllers that are integrated
on the system board assembly), drive backplanes or drive cables, back up all important data that is stored
on drives.
• If one or more NVMe solid-state drives are to be removed, it is recommended to disable them beforehand
via the operating system.
