Install the middle drive backplane
Use this information to install the middle 2.5-inch or 3.5-inch drive backplane.
About this task
Your server supports the following middle drive backplanes: 
•  Two 2.5-inch SAS/SATA 4-bay backplanes
•  Two 2.5-inch NVMe 4-bay backplanes
•  One 3.5-inch SAS/SATA 4-bay backplane
Attention: 
•  Read “Installation Guidelines” on page 185 to ensure that you work safely.
•  Power off the server and disconnect all power cords for this task.
•  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.
