Use this section to understand the SAS/SATA backplane cable routing for server model with eight 2.5'' front drives.
To connect cables for a 7mm drive backplane, refer to 7mm drive backplane.
To connect power cables for a backplane for standard 2.5'' or 3.5'' drives, refer to Cable routing for backplane power.
To connect cables for M.2 drives, refer to M.2 drive backplane.
To connect intrusion switch cable, refer to Intrusion switch.
To connect power cable for CFF RAID adapter, refer to CFF RAID adapter.
Cable routing for onboard configuration
The following illustrations and tables show the mapping relationship between backplane connectors and system board connectors for onboard configuration.
The following figure illustrates the cable routing for the onboard configuration of 8 x 2.5'' front SAS/SATA drive bays. Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n.

Backplane | From | To |
---|---|---|
Front BP (SAS) | 1 SAS 0, SAS 1 | 1 PCIe connector 7 |
Cable routing with an SFF HBA/RAID adapter
The following illustrations and tables show the mapping relationship between backplane connectors and an 8i or 16i SFF HBA/RAID adapter (Gen 3 or Gen 4).

Backplane | From | To |
---|---|---|
Front BP (SAS) | 1 SAS 0, SAS 1 | 1
