Install the Disk Backplane Signal Cable

Before installing the disk backplane signal cable, review the procedures for installing the 4 or 12 disk backplane in the server. See Install the 4-Drive Backplane and Install the 12-Drive Backplane.
  1. Unpack the replacement disk backplane signal cable and place it on an antistatic mat.
  2. Install the disk backplane signal cable between the disk backplane and motherboard connectors [1].

    Route the signal cable through the left-side cable trough and then through the motherboard handle.

    Ensure that the disk backplane signal cable is free from snagging motherboard components and other cables in the server. You might need to remove the SAS cables from the left-side cable trough before installing the disk backplane signal cable. See Remove SAS Storage Drive Cables.

  3. Reconnect the disk backplane signal cable to the disk backplane and the motherboard. Plug each end of the cable into its connector until you hear an audible click [2].

    Note:

    For information on reconnecting the disk backplane signal cable to the 4-disk backplane, see Install the 4-Drive Backplane.
  4. If necessary, reinstall SAS cables in the left-side cable trough.
