4 x 3.5'' AnyBay backplane (one processor)

Use this section to understand the AnyBay backplane cable routing for server model with four 3.5-inch front drives.

To connect cables for a 7mm drive backplane, refer to 7mm drive backplane.

To connect power cables for a backplane for standard 2.5-inch or 3.5-inch drives, refer to Cable routing for backplane power.

To connect cables for M.2 drives, refer to M.2 drive backplane.

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 for onboard configuration

The following table shows the mapping relationship between backplane connectors and processor board connectors for onboard configuration.

Cable routing with an SFF HBA/RAID adapter

The following table shows the mapping relationship between backplane connectors and processor board/adapter connectors when an 8i SFF HBA/RAID adapter (Gen 3 or Gen 4) is installed.

Note
Gen 3 and Gen 4 SFF HBA/RAID adapters are slightly different in their connectors, but the cable routing method is similar.
