2Remove the system cover (see "Removing the System Cover" on page 66).

3Open the expansion card cover (see Figure 3-7).

NOTE: You can remove the expansion card cover, if desired, and set it aside.

4Remove the filler bracket or existing expansion card to create a card-slot opening (see "Removing an Expansion Card" on page 93).

NOTE: Keep the filler bracket in case you need to remove the expansion card. Filler brackets must be installed over empty expansion card slots to maintain FCC certification of the system and protect against electromagnetic interference. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.

5Prepare the card for installation.

6Open the expansion card latch adjacent to the slot (see Figure 3-20).

7Insert the SAS controller card into expansion card slot 3 or slot 4 on the system board (see Figure 6-1) and press down firmly (see Figure 3-20). Ensure that the card is fully seated in the guide slot.

8Close the expansion card latch to secure the card in the system (see Figure 3-20).

NOTICE: Do not route card cables over or behind the cards. Cables routed over the cards can prevent the system cover from closing properly or cause damage to the equipment.

9Using the appropriate interface cable, connect the SAS controller card (connector 0) directly to the internal hard drives or to the SAS backplane, if installed.

NOTE: The cable must be connected according to the connector labels on the cable. The cable does not operate if reversed.

10Connect the SAS cable, LED cable, and RAID battery cable (if applicable) to the SAS controller card.

NOTE: For battery-cached SAS/RAID controllers, install the RAID battery (see "Installing a RAID Battery" on page 101).

11Close the expansion card cover (see Figure 3-7).

12Replace the system cover (see "Installing the System Cover" on page 67).

13Reattach any peripherals you disconnected, then connect the system to the electrical outlet.
