Connecting the cables
This topic provides instructions on the following cable connections:
• “Connecting the mini-SAS signal cable from the system board to the backplane for server models with
hot-swap hard disk drives” on page 35.
• “Connecting the mini-SAS signal cables from the RAID card to the backplanes for server models with
hot-swap hard disk drives” on page 36.
• “Connecting the SATA signal cables from the system board to the non-hot-swap hard disk drives”
on page 38.
Connecting the mini-SAS signal cable from the system board to the backplane for
server models with hot-swap hard disk drives
For server models with up to four 3.5-inch SATA hot-swap hard disk drives installed, you can use the
mini-SAS signal cable that has four SATA connectors and one Serial General Purpose Input/Output (SGPIO)
connector for cable connection.
To connect the mini-SAS signal cable from the system board to the backplane, do the following:
1. Connect the mini-SAS connector 1 to the mini-SAS signal cable connector 0 on the backplane. The
backplane is installed on the lower hard disk drive cage.
2. Connect the four SATA connectors 3 - 6 to the SATA connectors 0-3 on the system board.
3. Connect the SGPIO connector 2 to the SATA SGPIO connector on the system board.

To connect the power cable from the system board to the backplane, connect the 4-pin power connector on
one end of the power cable to the 4-pin power connector on the system board. Then, connect the other
power connector on the other end of the power cable to the power connector on the backplane.
