4 x 2.5'' NVMe backplane (two processors)
Use this section to understand the NVMe backplane cable routing for server model with four 2.5'' front drives.
To connect cables for M.2 drive backplane, refer to M.2 drive backplane.
To connect cables for a 7mm drive backplane, refer to 7mm drive backplane.
To connect cables for a rear NVMe drive backplane, refer to Rear NVMe/SAS/SATA drive backplane.
To connect power cables for a backplane for standard 2.5'' or 3.5'' drives, refer to Cable routing for backplane power.
To connect cables for intrusion switch, refer to Intrusion switch.
Cable routing for onboard configuration with two processors
The following table shows the mapping relationship between backplane connectors and system board connectors for onboard configuration.
The following figure illustrates the cable routing for the onboard configuration of 4 x 2.5'' front NVMe drive bays. Connections between connectors: 1 ↔ 1, 2 ↔ 2, 3 ↔ 3, ... n ↔ n
This cable routing is for the configuration without M.2 SATA/NVMe drive PCIe 4.0 backplane and front I/O module.
This cable routing is for the configuration with 7mm backplane and M.2 backplane, and without and front I/O module.
|Front BP (NVMe)||1 NVMe 0–1, NVMe 2–3||1 PCIe connectors 7, 8, and 9||Front BP (NVMe)||1 NVMe 0–1||1 PCIe connector 3|
|2 NVMe 2–3||1 PCIe connector 4|
