Removal and Replacement Procedures— Microtower (MT) Chassis
To install a processor backing plate:
1. Lay the new system board top down on a padded surface to protect the board from damage.
2. Remove the protective paper shield 1 from the mounting surface of the backing plate.
3. Position the mounting plate studs over the back of the sytem board 2 and press the plate
firmly to the system board so the studs penetrate the mounting holes.
To complete the installation of the system board, reverse the removal procedures.
