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

Front BP (NVMe)
Front BP (SAS)
Rear BP (if any)
Notes:
• *NVMe 4-5, NVMe 6-7, and NVMe 8-9 connectors are available only when the 10 x 2.5'' AnyBay front
backplane is used.
• *The SAS 2 connector only needs to be connected in the front drive scenario of 10 x 2.5'' AnyBay or 6 x
2.5'' SAS/SATA + 4 x 2.5'' AnyBay.
• In case of front 10 x 2.5'' NVMe drive bay scenario, SAS connectors on the front backplane do not need to
be connected.
The following figure illustrates the cable routing for the onboard configuration of 10 x 2.5-inch front drive
bays (6 x SAS/SATA + 4 x NVMe) with a rear 2 x 2.5-inch SAS/SATA drive cage. Connections between
