Cable routing for 2.5-inch drives to two backplanes

Use this section to understand how to route cables for 2.5-inch drives to two backplanes.

Note
Strictly observe the following instructions to avoid damaging cable sockets on the system board. Any damage to the cable sockets might require replacing the system board.

  • Connect cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.

  • To disconnect cables from the system board, do as follows:

    1. Press and hold all latches, release tabs, or locks on cable connectors to release the cable connectors.

    2. Remove the cable connectors vertically or horizontally in alignment with the orientations of the corresponding cable sockets, avoiding any tilt.
      Note
      The cable connectors might look different from those in the illustration, but the removal procedure is the same.






Following is the list of combinations of cable routing for 2.5-inch drives to two backplanes.

Connecting signal cables to two backplanes​

When there are two backplanes installed, see the following illustrations for cable routing.

8-bay backplane + 8-bay backplane​

Two options are available for this combination:

  1. With SATA/SAS RAID adapter (16i)

AnyBay backplane + 8-bay backplane​

Two processors installed

Two options are available for this combination:

Attention
When installing a AnyBay backplane and a 8-bay backplane, always install the AnyBay backplane to drive bay 0-7, and the 8-bay backplane to drive bay 8-15.

Four processors installed

Two options are available for this combination:

Note
  • When installing a AnyBay backplane and a 8-bay backplane, always install the AnyBay backplane to drive bay 0-7, and the 8-bay backplane to drive bay 8-15.
  • Install the processor and memory expansion tray before connecting the signal cables to NVMe connector on the expansion tray.
