Replacing the LOM Daughter Card

1. Angle the LOM card so that its NIC connectors are positioned toward the back-panel LOM card opening.
2. Straighten the card so that the cutouts on the side edges of the card insert into the two support standoffs. See Figure3-21.
3. Slide the card back slightly and align the front edge of the LOM card with the two front plastic retention standoffs adjacent to the LOM system board
connector, and press down the side of the card until it is fully seated. See Figure3-20.
When the front of the card is fully seated, the plastic standoff snaps over the edge of the card.
4. Reinstall all expansion cards in expansion-card riser 2. See Installing an Expansion Card.
5. Close the system. See Closing the System.
