• Each backplane your server supports offers multiple signal connections. This section singles out the
signal connection from power connection for better understanding. For backplane power connection, see
“Cable routing for backplane power” on page 165.
• For the locations of backplane signal connectors on the processor board and adapters, see
“System-
board-assembly connectors” on page 21
for details.
• For more information about backplanes supported and their connectors, see
“Drive backplane
connectors” on page 157

8x 2.5'' front drives (two processors)
Use the section to understand the cable routing for signal cable connections for 8 x 2.5–inch drive
backplanes.
Under the configuration of 8 x 2.5–inch front drives, your server supports the following front backplane:
•
“8 x 2.5'' SAS/SATA backplane (two processors)” on page 172
8 x 2.5'' SAS/SATA backplane (two processors)
Use this section to understand the SAS/SATA backplane cable routing for server model with eight 2.5-inch
front drives.
To connect power cables for a backplane for standard 2.5-inch or 3.5-inch drives, refer to
“Cable routing for
backplane power” on page 165
.
To connect cables for M.2 drives, refer to “M.2 drive backplane” on page 164.
To connect intrusion switch cable, refer to
“Intrusion switch” on page 161.
To connect power cable for CFF RAID adapter, refer to
“CFF RAID adapter” on page 159.
To connect signal cables for a backplane for standard 4 x 3.5-inch front drives, refer to the following cable
routing scenarios depending on your server configuration:
•
“Cable routing with an SFF HBA/RAID adapter” on page 172
• “Cable routing with a CFF RAID adapter” on page 173
Cable routing with an SFF HBA/RAID adapter
The following illustrations and tables show the mapping relationship between backplane connectors and an
8i or 16i SFF HBA/RAID adapter (Gen 3 or Gen 4).
