Note

  • NVMe drives are only supported in drive bays 6–9.

For power cable connection, see Power/Sideband cable routing.

Refer to the following cable routing for different configurations:
Note
When the SAS/SATA backplanes are connected to PCIe connectors on the system board, only SATA drives are supported. No SAS drives are supported.

Note

  • RAID/HBA adapters can be installed in PCIe slot 1 or internal riser assembly.

  • When a Gen 4 RAID/HBA adapter is installed, ensure that you use the corresponding Gen 4 cable:

Note

  • When the SAS/SATA backplanes are connected to PCIe connectors on the system board, only SATA drives are supported. No SAS drives are supported.

  • The cable routing illustration is based on the scenario that the rear hot-swap drive cage is installed. Depending on the model, the rear hot-swap drive cage might not be available on your server.
