Attention

• Read Installation Guidelines and Safety inspection checklist 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.

• 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.

• Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration information.
