Two 8 x SAS/SATA and one 8 x AnyBay (Gen 5) backplanes
This section provides cable routing information for the server model with two 8 x 2.5-inch SAS/SATA and one
8 x 2.5-inch AnyBay (Gen 5) front backplanes.
To connect power cables for the front backplane(s), refer to
“Backplanes: server models with 2.5-inch front
drive bays” on page 312
.
To connect signal cables for the front backplane(s), refer to the following cable routing scenarios depending
on your server configuration.
•
“32i RAID/HBA adapter” on page 418
• “32i RAID/HBA adapter + Retimer card” on page 419
• “8i RAID/HBA adapters + Retimer card” on page 420
32i RAID/HBA adapter
The following shows the cable connections for the front (16 x 2.5-inch SAS/SATA + 8 x 2.5-inch Gen 5
AnyBay) configuration with one 32i RAID/HBA adapter when one processor is installed.
Connections between connectors:
1 ↔ 1 , 2 ↔ 2 , 3 ↔ 3 , ... n ↔ n
