Cable routing for onboard configuration
The following table shows the mapping relationship between backplane connectors and system board
connectors for onboard configuration.
Table 22. Mapping between backplane connectors and system board connectors for onboard configuration
Backplanes From To
Front BP (NVMe) NVMe 0-1*, 2-3* PCIe 1, PCIe 2
Front BP (SAS) SAS SATA 0
Rear BP (if any)
SAS SATA 2
NVMe 0, NVMe 1
PCIe 6
Note: *NVMe 0-1 and NVMe 2-3 connectors are available only when the 4 x 3.5'' AnyBay front backplane is
used.
The following figure illustrates the cable routing for the onboard configuration of 4 x 3.5-inch front AnyBay
drive bays with a rear 2 x 2.5-inch NVMe drive cage. Connections between connectors:
1 ↔ 1 , 2 ↔ 2 , 3 ↔
3 , ... n ↔ n
