4. Disconnect all cables from the system board.
5. Remove the microprocessor fan.
6. If a 5.25-inch drive is installed in the lower of the two external bays, remove it or pull it forward far enough to not interfere with the system board removal.
7. Remove the screw that secures the system board to the bottom of the chassis.
8. Slide the system board toward the front of the chassis until it stops.
9. Carefully lift the system board out of the chassis (be sure to lift evenly and not twist the system board).

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).
