PCI slot A1 Removing an Add-in Board CAUTION 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. 1. Observe the safety and ESD precautions at the beginning of this 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 scrape the board against other components. 5. Store board in an antistatic protective wrapper. 6. If you are not reinstalling a board in the same slot, install a slot cover over the vacant slot. The tapered foot of the cover must fit into the mating slot in the expansion slot frame. 7. Use the screw removed earlier to fasten the new board to the chassis. Tighten the screw firmly (6.0 inch-pounds). 8. Running the SSU is optional after you remove a PCI or ISA board. 93
