Installing a SAS Controller Card

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2Open the system. See "Opening the System" on page 65.

3Install the controller card in the expansion slot labeled

INTERNAL_STORAGE.

For instructions on installing the card, see "Installing an Expansion Card" on page 78.

4Connect the card to the SAS backplane

a Connect the SAS data cable connector labelled "Controller 0" to the white connector on the card, and the connector labelled "Controller 1" to the black connector on the card. See Figure 3-26.

b Route the SAS data cable through the cable clips on the inner side of the chassis. Attach the connector labeled "BKPLN A" to connector SAS A on the backplane, and attach the connector labeled "BKPLN B" to connector SAS B on the backplane.
