standoffs. See Figure3-20.

When the front of the card is fully seated, the plastic standoff snaps over the edge of the card.



9. Connect the two short ribbon cables to the RAC card and the system board. See Figure6-2 for the connector locations

a. Connect one cable to connector 1 on the RAC card and to RAC_CONN1 on the system board.

b. Connect the second cable to connector 2 on the RAC card and to RAC_CONN2 on the system board.



j. Reinstall expansion-card riser 1. See Replacing Expansion-Card Riser 1.



k. Reinstall all expansion cards in expansion-card riser 1. See Installing an Expansion Card.



l. Close the system. See Closing the System.

See the RAC card documentation for information on configuring and using the RAC card.

3. Remove all expansion cards from expansion-card riser 2. See Removing an Expansion Card.



4. Pull back slightly on the two blue retention standoff tabs at the front edge of the card and gently work the edge of LOM card off of the standoffs.

As the card releases from the standoffs, the connector under the LOM card disengages from the system board.



5. Slide the card back to release the back edge of the card from the two support standoffs and lift the card out of the system.

NOTICE: Be careful when attaching cables to the system board that you do not damage the surrounding system board components.

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as

authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not

authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
