Note: Slot covers must be installed on all vacant expansion slots. This maintains the
electromagnetic emissions characteristics of the system and ensures proper cooling of
system components.

chapter.
2. Disconnect any cables attached to the board you are removing.
3. Remove and save the screw that attaches the existing board retaining bracket to the
chassis.
4. Holding the board by its top edge or upper corners, carefully pull it out. Do not
