Onboard connectors

The following shows the cable connections for the front (8 x 3.5-inch SAS/SATA + 4 x 3.5-inch NVMe) configuration with onboard connectors.

Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n

Cable routing when two processors installed​

To connect the processor interconnection cable when two processors are installed, see Processor interconnection cable routing.
