Remove the Disk Backplane Signal Cable

Before removing the disk backplane signal cable, review the procedures for removing the 4 or 12 disk backplane from the server. See Remove the 4-Drive Backplane and Remove the 12-Drive Backplane.
  1. Prepare the server for service.
    1. Power off the server.
    2. Disconnect the power cords from the power supplies.
    3. Extend the server to the maintenance position.
    4. Attach an antistatic wrist strap.
    5. Remove the server top cover.
    6. Remove the air baffle.
    7. Remove the fan modules from the server.
    8. Remove the fan tray from the server.
  2. Locate the disk backplane signal cable.

    The disk backplane signal cable is connected between the 4 or 12 disk backplane and the motherboard connector, which is located between PCIe slot 4 and the motherboard handle. The signal cable is routed from the disk backplane, through the left-side cable trough, and then through the motherboard handle before connecting to the motherboard [1, 2].


    Figure showing the disk backplane signal cable being removed from the server.

  3. Disconnect and remove the disk backplane signal cable from the server.
    1. Disconnect the signal cable from the disk backplane and the motherboard [1].

      At each end of the signal cable, press and hold the connector to disengage the locking mechanism, then gently lift the connector from the disk backplane and motherboard.

      Note:

      For information on disconnecting the disk backplane signal cable from the 4-disk backplane, see Remove the 4-Drive Backplane.
    2. Remove the cable from the server.

      Gently direct the cable through the motherboard handle and then lift the cable from the left-side cable trough [2].

      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 removing the disk backplane signal cable. See Remove SAS Storage Drive Cables.
