connect the mini-SAS connector on the other end of the cable to the mini-SAS ports 0-3 on the
backplane.

another mini-SAS to mini-SAS signal cable and connect the mini-SAS connector on one end of the
cable to the SAS connector 4-7 on the system board. Then, connect the mini-SAS connector on the
other end of the cable to the mini-SAS ports 4-7 on the backplane.
