Watch the procedure. A video of the installation process is available:
  1. Install the three 2.5-inch NVMe 8-Bay backplanes. See Install the 2.5-inch-drive backplane. Then, apply drive bay sequence labels above the drive bays on your server.
  2. Install the bracket on one 810-4P NVMe switch adapter. To install the bracket, align the screw holes in the bracket with the corresponding holes in the switch adapter, and then install the screws to secure the bracket to the switch adapter.
  3. Install the 810-4P NVMe switch adapter in the RAID adapter slot on the system board. See Install the RAID adapter.
  4. Install the 810-4P NVMe switch adapter with 2U bracket in PCIe slot 4 on the system board. See Install a PCIe adapter on the system board.
  5. Install the riser card 1 on riser 1 bracket. See Install a riser card.
  6. Install the 1610-4P NVMe switch adapter in PCIe slot 1 on riser card 1. See Install a PCIe adapter on the riser assembly.
  7. Install the riser 1 assembly to the chassis. See Install a riser card.
  8. Install the riser card 2 on riser 2 bracket. See Install a riser card.
  9. Install one 1610-4P NVMe switch adapter in PCIe slot 5 on riser card 2. Then, install the other 1610-4P NVMe switch adapter in PCIe slot 6 on riser card 2. See Install a PCIe adapter on the riser assembly.
  10. Install the riser 2 assembly to the chassis. See Install a riser card.
  11. Install any required hardware or server options, and then cable the server. For information about how to connect cables for server models with twenty NVMe drives, see Server model: twenty 2.5-inch NVMe drives, two NVMe 810-4P switch adapters, three NVMe 1610-4P switch adapters in the topic Server models with twenty 2.5-inch drives.
