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.

| From | To | From | To |
1 Power connector on backplane | Onboard: backplane 1 power connector | 1 Power connector 1 on backplane | Onboard: backplane 1 power connector |
|
| 2 Power connector 2 on backplane | Onboard: backplane 2 power connector |
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.
