Drive backplane cable routing: 2.5-inch chassis without Compute Complex Neptune Core Module
This section provides backplane cable connection information for server models with 2.5-inch front drive bays and without Compute Complex Neptune Core Module.
Power cable connections
- For connectors on each drive backplane, see Drive backplane connectors.
Front backplanes (BP1/2/3):
8 x 2.5-inch SAS/SATA front backplane
8 x 2.5-inch AnyBay front backplane (also used as an 8 x 2.5-inch NVMe front backplane when only NVMe connectors on the backplane are cabled)
Middle backplanes (BP10/11):
4 x 2.5-inch SAS/SATA middle/rear backplane
4 x 2.5-inch AnyBay middle/rear backplane (also used as a 4 x 2.5-inch NVMe middle/rear backplane when only NVMe connectors on the backplane are cabled)
Rear backplane (BP9):
4 x 2.5-inch SAS/SATA middle/rear backplane
4 x 2.5-inch AnyBay middle/rear backplane (also used as a 4 x 2.5-inch NVMe middle/rear backplane when only NVMe connectors on the backplane are cabled)
8 x 2.5-inch SAS/SATA rear backplane
The following uses the 4 x 2.5-inch middle/rear backplane as an example of BP9 for illustration. The cable routing for 8 x 2.5-inch rear backplane is similar.
| From | To (processor board) | Length |
|---|---|---|
| 1 BP1: PWR | 1 PWR 1 | 250 mm |
| 2 BP2: PWR | 2 PWR 2 | 250 mm |
| 3 BP3: PWR | 3 PWR 3 | 250 mm |
| 4 BP10: PWR | 4 PWR 23 | 250 mm |
| 5 BP11: PWR | 5 PWR 21 | 250 mm |
| 6 BP9: PWR | 6 PWR 12 | 250 mm |
Signal cable connections
Refer to the specific topic for signal cable connections depending on the backplanes you have installed.
