SAS Controller Daughter Card
Your system includes a dedicated slot on the sideplane for a SAS controller
daughter card. The SAS controller daughter card provides the SAS storage
subsystem for your system’s internal hard drives. The SAS controller daughter
card is shown in Figure 3-12.
Installing a SAS Controller Daughter Card
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Opening the System" on page 67.
3 Disconnect the control panel cable from the sideplane board. See
"Removing the Control Panel Assembly" on page 122.
4 Hold the SAS daughter card by its edges with the card connector facing
the sideplane board.
5 Aligning the chassis slots on the SAS daughter card tray with the
corresponding hooks on the chassis, insert the card connector into the SAS
daughter card connector on the sideplane board. See Figure 3-12.
Ensure that the card is aligned with the mid-section standoff on the SAS
controller daughter card and fully seat the card in the sideplane board.
