4 x 3.5'' AnyBay backplane

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

To connect power cables for a backplane for standard 2.5'' or 3.5'' drives, refer to Backplane power cable routing.

To connector cables of RAID flash power modules, refer to RAID flash power modules.

To connect signal cables, refer to the following cable routing scenarios depending on your server configuration:

Cable routing with an SFF HBA/RAID adapter

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