8If you are not replacing the RAC card, disconnect and remove the ribbon cables from the RAC card and insert the plastic filler plug in the system back panel.
NOTICE: When detaching the RAC cables from the system board, squeeze the metal ends of the cable connectors and gently work the connector out of the socket. Do not pull on the cable to unseat the connector. Doing so can damage the cable.
9Close the system. See "Closing the System" on page 69.
Installing a 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 69.
3Remove any expansion card that is already installed on the riser board. See "Removing an Expansion Card" on page 96.
4Remove the plastic filler on the rear wall of the system. See Figure
5Connect the ribbon cable to the RAC card.
NOTE: You must perform this step before connecting the RAC card to the system board. Once the card is fully seated on the standoffs, it will be difficult to connect the ribbon cable to the RAC card and to the system board.
6Angle the RAC card so that its NIC connector inserts through the back- panel RAC card opening, and then straighten the card. See Figure
7Position the back edge of the card so that the cutout on the edge of the card inserts into the support standoff. See Figure
8Align the front edge of the RAC card with the two front plastic retention standoffs and press down the side of the card until it is fully seated on the standoffs. See Figure
When the front of the card is fully seated, the plastic standoff snaps over the edge of the card.
