Important notices for handling the system board:
When handling the system board, bear the following in mind.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a corrugated
conductive surface.
