One 8 x SAS/SATA backplane
This section provides cable routing information for the server model with one 8 x 2.5-inch SAS/SATA front 
drive backplane.
To connect power cables for the front backplane(s), refer to 
“Backplanes: server models with 2.5-inch front 
drive bays” on page 297
.
To connect signal cables for the front backplane(s), refer to the following cable routing scenarios depending 
on your server configuration.
