8 x 2.5'' U.3 drives with 10 x 2.5'' AnyBay backplane

Use this section to understand the cable routing for eight U.3 drives with 10 x 2.5 Anybay backplane.

For the locations of connectors on the processor board, refer to System-board-assembly connectors.
To connect power cables for 2.5-inch drive backplanes, refer to Power/Sideband cable routing.
To connect power and input cables for CFF RAID/HBA adapters, refer to CFF RAID/HBA adapter.
To connect power and sideband cables for the rear drive backplane, refer to Rear NVMe/SATA drive backplane.
To connect power and sideband cables for the 7mm drive backplane, refer to 7mm drive backplane.
To connect cables for RAID flash power modules, refer to RAID flash power modules.
