CFF 16i RAID/HBA adapter + Retimer card

The following shows the cable connections for the front (16 x 2.5-inch SAS/SATA + 8 x 2.5-inch Gen 5 NVMe) configuration with one CFF 16i RAID/HBA adapter and one retimer card.

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

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