This topic provides cable routing information for the 12 x 3.5-inch SAS/SATA front backplane, two 4 x 2.5-
inch SAS/SATA middle backplanes, and one 4 x 2.5-inch/8 x 2.5-inch SAS/SATA rear 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.
