SAS Controller Daughter Card
Your system includes a dedicated slot on the sideplane for an optional SAS controller daughter card. The
SAS controller daughter card provides the SAS storage subsystem for your system’s two optional internal
hard drives. The optional SAS RAID controller daughter card allows you to set up any internal hard drives
in a RAID configuration.

releasing the tab on the cable connector on the daughter card. See Figure 3-26.
2 Pull on the release latch on the daughter card (see Figure 3-8) and slide the daughter card tray towards the
hard drives.
3 Continue to hold the guide rails outward as you pull the SAS controller daughter card upward from the
rails.
Installing a SAS Controller Daughter Card or SAS RAID Controller Daughter Card
NOTICE: If you are installing a SAS RAID daughter card, be careful not to press on the memory module on the
card (see Figure ). to avoid damaging the memory module or its socket.
NOTICE: If you are installing a new or replacement SAS RAID daughter card, do not remove the card’s plastic
cover until you have completed installing the card.
1 Hold the metal daughter card tray by its edges with the release latch and edge connector facing the
sideplane board. See Figure 3-8.
2 Align the two slots in the daughter card tray and the corresponding tabs on the chassis, then lower the card
tray onto the chassis.
3 Slide the daughter card tray towards the sideplane until the edge connector on the daughter card fits into
the socket on the sideplane board and the release latch engages. See Figure 3-8.
