2.5-inch drive backplane cable routing

Use the section to understand the cable routing for the 2.5-inch drive backplane.

Based on the location of the drive backplane, select the corresponding routing plan:

After you finish

Divide the cables connected to the PCIe switch board into four bundles, and secure them with cable ties.


BundleCable
1
  • Two backplane 1 signal cables (connected to NVMe connectors 1 and 2)
  • Two PCIe switch board signal cables (connected to MCIO connectors 1 and 2)
2
  • Two backplane 1 signal cables (connected to NVMe connectors 3 and 4)
  • Two PCIe switch board signal cables (connected to MCIO connectors 3 and 4)
3
  • Two backplane 2 signal cables (connected to NVMe connectors 5 and 6)
  • Two PCIe switch board signal cables (connected to MCIO connectors 5 and 6)
4
  • Two backplane 2 signal cables (connected to NVMe connectors 7 and 8)
  • Two PCIe switch board signal cables (connected to MCIO connectors 7 and 8)
