4 x 3.5'' AnyBay backplane (one processor)

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.

Cable routing for onboard configuration​

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