The server supports up to three 2.5-inch drive backplanes of below types. Depending on the backplane type 
and quantity, the installation location of the backplanes varies.  
•  2.5-inch SAS/SATA 8-bay backplane
•  2.5-inch Anybay 8-bay backplane
•  2.5-inch NVMe 8-bay backplane
Note: The Anybay backplane and NVMe backplane listed above use the same physical circuit board. The 
difference is which connectors on the backplane are cabled: NVMe and SAS/SATA, or just NVMe.
The following table lists the supported backplane combinations. Install the backplane according to your 
server configuration.

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.
