Installing System Components 99Installing the SAS Controller Daughter CardThe following procedure applies to either a SAS controller or a SAS RAID controller daughter card.1 Hold the daughter card by its edges and align the card with the slide rails on the expansion-bay bracket.See Figure 3-28.NOTE: When pushing the SAS controller daughter card into the socket connector, push only on the card edgesand not on the DIMM or any part of the DIMM socket on the daughter card.2 Insert the card into the slide rails and slide the card down until the card-edge connector seats into thededicated storage socket (INT STORAGE) on the system board. See Figure 3-14 and Figure 3-28.3 If present, connect the battery cable to the battery cable connector on the SAS controller daughtercard.If you need to replace the SAS daughter card battery, see "Replacing the SAS RAID Controller DaughterCard Battery" on page 96.Cabling the SAS Backplane BoardsCable RequirementsThe cables needed to connect the SAS storage system depend on your configuration. Table 3-2 providesa listing of the available configurations for your SAS storage, the number of cables required, and thenumber of hard drives supported in each configuration.Cabling the SAS Controller (Non-RAID)For a system with a non-RAID SAS controller daughter card installed, connect SAS_0 on the SAScontroller daughter card to connector SAS_A on the SAS backplane board. See Figure 3-29.Table 3-2.
