32i RAID/HBA adapter
The following shows the cable connections for the 12 x 3.5-inch SAS/SATA configuration with a 4 x 3.5-inch
SAS/SATA middle backplane and a 4 x 3.5-inch/4 x 2.5-inch SAS/SATA rear backplane.

Notes:
• For a 4 x 3.5-inch SAS/SATA rear backplane, the 32i adapter
1
is installed on PCIe slot 3.
• For a 4 x 2.5-inch SAS/SATA rear backplane, the 32i adapter
1
is installed on PCIe slot 2.
Below illustration uses the 4 x 3.5-inch SAS/SATA rear backplane as an example for cable routing. Cable
routing for the 4 x 2.5-inch SAS/SATA rear backplane is similar.
Connections between connectors:
1 ↔ 1 , 2 ↔ 2 , 3 ↔ 3 , ... n ↔ n
