2.5-inch drive backplane cable routing (server model with four PCIe risers)
Follow the instructions in this section to learn how to do 2.5-inch drive backplane cable routing for the server model with four PCIe risers.
- Remove the fans. See Remove a fan.
- Remove the fan cage. See Remove the fan cage.
Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n
The Cable PN or FRU PN can be found on the label attached to the cable.
When routing the cables, make sure that all cables are routed appropriately through the corresponding cable guides and cable clips.
The AnyBay backplane is used as a pure NVMe backplane when no RAID/HBA adapters are installed.

SAS/SATA cable routing
Based on the location of the adapter, select the corresponding routing path for SAS/SATA cable from the following table.
| SAS/SATA cable routing to riser A | SAS/SATA cable routing to riser B | |
|---|---|---|
 |  | |
| SAS/SATA cable routing to riser D | SAS/SATA cable routing to riser C | |
| | |
| From | To | Cable |
| 1 Backplane 1: SAS/SATA | 1 RAID/HBA adapter |
|
| 2 Backplane 2: SAS/SATA | 2 RAID/HBA adapter |
|
| 3 Backplane 3: SAS/SATA | 3 RAID/HBA adapter |
