Dell 2900 Cabling the SAS Backplane Boards, Installing the SAS Controller Daughter Card

Installing the SAS Controller Daughter Card

The following procedure applies to either a SAS controller or a SAS RAID controller daughter card.

1Hold 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 edges and not on the DIMM or any part of the DIMM socket on the daughter card.

2Insert the card into the slide rails and slide the card down until the card-edge connector seats into the dedicated storage socket (INT STORAGE) on the system board. See Figure 3-14 and Figure 3-28.

3If present, connect the battery cable to the battery cable connector on the SAS controller daughter card.

If you need to replace the SAS daughter card battery, see "Replacing the SAS RAID Controller Daughter Card Battery" on page 96.

Cabling the SAS Backplane Boards

Cable Requirements

The cables needed to connect the SAS storage system depend on your configuration. Table 3-2 provides a listing of the available configurations for your SAS storage, the number of cables required, and the number of hard drives supported in each configuration.

Table 3-2. Cable Requirements

Configuration	Cables Required	Hard Drives Supported
SAS controller	1	4 (bays 0 through 3)
SAS RAID controller /no 1x2 flex bay	2	8 (bays 0 through 7)
backplane
SAS RAID controller /1x2 flex bay	3	10 (bays 0 through 9)
backplane

Cabling the SAS Controller (Non-RAID)

For a system with a non-RAID SAS controller daughter card installed, connect SAS_0 on the SAS controller daughter card to connector SAS_A on the SAS backplane board. See Figure 3-29.
