M.2 drive backplane cable routing (power & signal)

M.2 drives can be installed on the chassis (scenario 1) or 3.5-inch front drive cage (scenario 2). The figure illustrates cable connections in scenario 1. The cable connections for the other scenario is the same.

Cable routing for M.2 drives

1 Power cableM.2 power connector on the system board
2 M.2 signal cable
  • PCIe connector 1 or 4 on the system board (two processors installed)note

  • PCIe connector 1 on the system board (one processor installed)

When two processors are installed, the M.2 signal cable needs to be connected to PCIe connector 4 only when your server is configured with one of the following front drive backplanes:
  • 10 x 2.5'' (10 AnyBay)

  • 10 x 2.5'' (10 NVMe)

  • 10 x 2.5'' (8 AnyBay + 2 NVMe)
