Grasp the card by its top corners, and carefully pull it out of its connector. Reinsert the card in its connector, and carefully push it in until it is fully seated. Then reinstall the card-mounting bracket’s retaining screw (see “Expansion Cards” in Chapter 4 or 5 for more information).

If you are replacing a system board, remove the DIMMs, the primary microprocessor SEC cartridge/heat sink assembly, and the terminator card or secondary microprocessor assembly, and install them on the replacement board. When you reinstall the system board, before you slide the system board back to lock it in position, push down near each slot to engage the grounding clip onto its corresponding tab. Push evenly on both sides of the system board as you slide it into position (do not twist the system board).
