end of the cable to the mini-SAS signal cable connector 0 on the backplane for 2.5-inch hard disk
drives or to the mini-SAS signal cable connector on the backplane for 3.5-inch hard disk drives. The
backplane for 3.5-inch hard disk drives is installed on the lower hard disk drive cage.
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
card. Then, connect the mini-SAS connector
cable connector 1 on the backplane for 2.5-inch hard disk drives or to the mini-SAS signal cable
connector on the backplane for 3.5-inch hard disk drives. The backplane for 3.5-inch hard disk drives
is installed on the upper hard disk drive cage.
• If you are using a ThinkServer RAID 500 Adapter, do the following:
