Backplanes: server models with 3.5-inch front drive bays

This section provides backplane cable connection information for server models with 3.5-inch front drive bays.

Before you start​

Ensure below parts are removed before starting cable routing for front backplanes.

Power cable connections​

The server supports the following 3.5-inch front drive backplanes:

  • 8 x 3.5-inch SAS/SATA backplane

  • 12 x 3.5-inch SAS/SATA backplane

  • 12 x 3.5-inch AnyBay backplane

  • 12 x 3.5-inch SAS/SATA expander backplane

For connectors on each drive backplane, see Drive backplane connectors.

Note
If there is a supercap holder installed between the front backplane and the system board assembly, connect the power cables as below:

  • Connect power connector 1 on the backplane to the backplane 2 power connector on the system board assembly

  • (For the backplane with two power connectors) Connect power connector 2 on the backplane to the backplane 3 power connector on the system board assembly.

Signal cable connections​

Refer to the specific topic for signal cable connections depending on the backplanes you have installed.
