CAUTION Do not overtighten the screws to the Fastex fasteners. If you do, the fasteners may distort or
the screw holes may become stripped. While the system board is out, it is possible for the
Fastex fasteners to become dislodged.
To remove the system board:
1. Remove cables connected to the system and option cards, taking note of cable
connections and orientation.
2. Detach the air duct by removing the two screws securing it to the chassis, and then
gently remove the air duct.
3. Lay the chassis down on its right side.
4. Note the locations where all cables connect to the system board.
5. Disconnect all cables from the system board.
6. Note the locations of the option cards, remove them by following instructions in the next

WARNING Use care when removing or installing the screws to avoid damaging components on
the system board.
