Connecting cables to the NVMe switch cards

Follow the instructions in this section to learn how to connect cables to the NVMe switch cards.

1. Complete the procedure in Connecting cables to the processor and memory expansion tray.
2. Install the 4U PCIe expansion tray (see Install the 4U PCIe expansion tray).
3. Rout the four PCIe cables in the following order:
   1. through the side cable guide in the chassis
   2. through the cable clips on the processor and memory expansion tray
   3. through the spine of the 4U PCIe expansion tray

   Note

   Make sure to match the drive backplane and NVMe switch card connectors as following:

   Table 1. Drive backplane and NVMe switch card connectors

   AnyBay/NVMe drive backplane connector	Switch card connector
   0-1	C0
   2-3	C1
   4-5	C0
   6-7	C1

5. Open the retainers of x16/x16 4U PCIe riser cage, and install the two NVMe switch cards to corresponding slots:

   Table 2. NVMe switch cards and corresponding PCIe slot numbers

   	AnyBay/NVMe drive backplane connectors	PCIe slot number
   1	0-1, 2-3	Slot 10
   2	4-5, 6-7	Slot 12
