Removing an SBus Card

1. Use the procedures in "Removing a Board", to remove the applicable I/O+ board.

2. Use Figure 4-12 to locate the card to be removed.

3. Remove the two screws that secure the SBus card to the back panel.

   Save the screws for installation of a replacement SBus card or a filler panel.

4. Unlock the SBus card by pulling up the tips of the two standoff (Figure 4-14).

5. Hold the card by the edges near the connector and gently rock the card back and forth to loosen it from the socket.

   You may have to remove the SBus cards or the FFB card next to this card in order to have enough room to hold onto the SBus card being removed.

   Caution -

   The connector housing may break if the SBus card is tilted too far.

6. Lift the SBus card from the socket at an angle while guiding the face plate out from the back panel opening (Figure 4-15).

7. Place the SBus card in an antistatic bag for protection.

8. If the SBus card is not immediately replaced, install a filler panel (part number 340-2305) on the I/O+ board back panel opening. To secure the filler panel, use the screws that were removed in Step 1.

   Caution -

   Be sure to install the filler panel right-side up. Installing it upside down creates a gap at the top edge of the SBus slot opening that can impair system cooling and FCC regulatory compliance.
