To connect cables from the RAID card to the backplane, do one of the following depending on the type of
your RAID card:
• If you are using a ThinkServer RAID 500 Adapter, do the following:
1. Use the mini-SAS to mini-SAS signal cable. Connect the mini-SAS connector 1 to the port 0 on the
RAID card. Then, connect the mini-SAS connector
2 to the mini-SAS ports 0-3 on the backplane.
2. If your server has more than four hard disk drives installed, use the other mini-SAS to mini-SAS
signal cable. Connect the mini-SAS connector
3 to the port 1 on the RAID card. Then, connect the
mini-SAS connector 4 to the mini-SAS ports 4-7 on the backplane.
• If you are using a ThinkServer RAID 700 Adapter, do the following:
1. Use one mini-SAS to mini-SAS signal cable. Connect the mini-SAS connector 3 to the ports 3-0 on
the RAID card. Then, connect the mini-SAS connector 4 to the mini-SAS ports 0-3 on the backplane.
2. If your server has more than four hard disk drives installed, use the other mini-SAS to mini-SAS signal
cable. Connect the mini-SAS connector 1 to the ports 7-4 on the RAID card. Then, connect the
mini-SAS connector 2 to the mini-SAS ports 4-7 on the backplane.
Figure 28. Connecting cables from the RAID card to the backplane
Refer to the following topics for information about the connector locations and the power cable connections:
• “Hot-swap hard disk drive backplane” on page 35
• “RAID card” on page 33
• “System board components” on page 41
Connecting cables from the RAID card to the expander card, and then from the expander card to
the backplanes
To support more than eight and up to 16 2.5-inch hard disk drives, your server must have a supported RAID
card and an expander card installed. You need to connect cables from the RAID card to the expander card,
and then from the expander card to the backplanes.
Use the following instructions to connect cables from the RAID card to the expander card rst:
• If you are using a ThinkServer RAID 500 Adapter, do the following:
1. Use a mini-SAS to mini-SAS signal cable and connect the mini-SAS connector on one end of the
cable to the port 0 on the ThinkServer RAID 500 Adapter. Then, connect the mini-SAS connector on
the other end of the cable to the connector 1 on the expander card.
