Cable routing for 2.5-inch drives to two backplanes
Use this section to understand how to route cables for 2.5-inch drives to two backplanes.
Following is the list of combinations of cable routing for 2.5-inch drives to two backplanes.
Connecting signal cables to two backplanes
When there are two backplanes installed, see the following illustrations for cable routing.
8-bay backplane + 8-bay backplane
Two options are available for this combination:
With SATA/SAS RAID adapter (16i)

AnyBay backplane + 8-bay backplane
Two processors installed
Two options are available for this combination:
Attention
When installing a AnyBay backplane and a 8-bay backplane, always install the AnyBay backplane to drive bay 0-7, and the 8-bay backplane to drive bay 8-15.

Four processors installed
Two options are available for this combination:
Note
- When installing a AnyBay backplane and a 8-bay backplane, always install the AnyBay backplane to drive bay 0-7, and the 8-bay backplane to drive bay 8-15.
- Install the processor and memory expansion tray before connecting the signal cables to NVMe connector on the expansion tray.
