This section provides cable routing information for the server model with one 8 x 2.5-inch NVMe front
backplane.
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.
