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.

Figure 1. M.2 cable routing

From	To
1 Power cable	M.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) Note 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)
