One 8 x SAS/SATA and one 8 x NVMe (Gen 4) backplanes
This section provides cable routing information for the server model with one 8 x 2.5-inch SAS/SATA 
backplane and one 8 x 2.5-inch NVMe backplane (Gen 4).
To connect power cables for the front backplane(s), refer to 
“Backplanes: server models with 2.5-inch front 
drive bays” on page 297
.
To connect signal cables for the front backplane(s), refer to the following cable routing scenarios depending 
on your server configuration.
• 
“Onboard connectors” on page 324
•  “Onboard connectors + 8i RAID/HBA adapter” on page 325
•  “Onboard connectors + CFF 16i RAID/HBA adapter” on page 327
