Installing an Optional RAC 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.

3Remove the plastic filler plug from the system back panel. See Figure 1-3.

4Temporarily remove the storage controller card from the expansion slot labeled INTERNAL STORAGE:

a Disconnect all cables from the card.

b Grasp the storage controller card by its edges, and carefully remove it from the card connector.

5Install the RAC card in the slot labeled RAC_CONN:

a Angle the RAC card so that the NIC connector fits through the back- panel RAC NIC opening. See Figure 3-14.

b Position the card so that the card-edge connector aligns with the expansion-card connector.

c Insert the card-edge connector firmly into the expansion-card connector until the card is fully seated.

6Connect the 50-pin management cable and the 44-pin MII cable supplied with the RAC to the two connectors on the RAC card (see Figure 3-14), and to the two corresponding connectors on the system board (see Figure 6-1).
