Installing the 8x2.5-inch hot-swap drive backplane with controller expander

Use this information to install the 8x2.5-inch hot-swap drive backplane with controller expander.

Note
  • For more information about the connecting the SAS cables to the drive backplane, (see Connecting the SAS cables).
  • When you install this backplane, it attaches to the drive backplane that is next to it in the configuration, using the two interposer cables that come with this backplane. See Supported SAS/SATA drive backplane configurations for the supported configurations that use this drive backplane.
  • Install this backplane in backplane bays 3 and 4 only. It cannot be installed in drive backplane bays 1 and 2. It is not supported.

To install the 8x2.5-inch hot-swap drive backplane with controller expander, complete the following steps:

  1. Read the safety information and installation guidelines, see Safety and Installation guidelines.
  2. Turn off the server (see Turning off the server) and all attached peripheral devices. Disconnect all power cords; then, disconnect all external cables from the server.
  3. Remove the top cover (see Removing the server top cover).
  4. Remove the fan cage assembly (see Removing the fan cage assembly).
  5. Remove the microprocessor and memory expansion tray (see Removing the microprocessor and memory expansion tray assembly) or DIMM air baffle (see Removing the DIMM air baffle), whichever one is installed.
  6. Open the SAS cable guide cover.
  7. If backplane filler panels are installed in the backplane bays in which you are installing the backplane, remove the backplane filler panels.
  8. Connect the two 10x2-pin power connectors on the combination power/configuration cable to the backplane power connectors on the system board. The power connector on the end of the black cable (which might be labelled 1/3) connects to backplane connectors 3 on the system board. The power connector on the end of the gray cable (which might be labelled 2/4) connects to backplane connectors 4 on the system board. Connect the configuration connector on the combination power/configuration cable to the configuration connector on the backplane. Connect the other power connector on the combination power/configuration cable to the power connector on the backplane.
    Note
    You can connect the cables to the backplane before you install the backplane onto the cage, or you can connect the cables after you install the backplane, if that is easier for you.

  9. Insert the drive backplane tabs into the slots on the bottom of the backplane cage and rotate the backplane assembly forward until the backplane locks into place.

  10. Connect the two interposer cables (that are attached to this backplane) to the signal connectors on the other backplane in this configuration. The shortest cable connects to the closest SAS signal connector on the other backplane. The longest cable connects to the farthest SAS signal connector on the other backplane.
  11. Connect the SAS signal cables to the two SAS signal connectors on the system board and route the cables through the SAS cable guide; then, connect the other end of the signal cables to the backplane assembly.

  12. Close the SAS cable guide cover.

If you have other devices to install or remove, do so now. Otherwise, go to Completing the installation.
