Note:
You can reconnect the cables to the hard disk drive backplane before installing the
backplane onto the brackets or you can connect the cables after you install the backplane, if that is
easier for you.

Step 13. Connect the SATA power cable, the SATA signal cable, and the configuration cable to the hard disk
drive backplane (see “Internal cable routing and connectors” on page 44 ).
Note:
The configuration cable will not be shipped with this option. The configuration cable is
already installed from the system board to the original backplane, this cable is two drops chained
cable. Connect the end of this cable to the newly-added 4 Pac HDD backplane.
Step 14. Connect the other end of the SATA signal cable to the connector on the SAS/SATA adapter (see
Step 8 in “Installing a ServeRAID SAS/SATA controller on the SAS/SATA RAID riser card” ).
Step 15. Reinstall the hard disk drives and filler panels.
If you have other devices to install or remove, do so now. Otherwise, go to “Completing the installation” on
page 100 .
