1140 System board assembly
Important notices for handling the system board:
When handling the system board, bear the following in mind:
• The system board has an accelerometer, which can be broken if several thousands of G-forces are applied.
Note:
Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench can subject
the accelerometer to as much as 6000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite.
• If a system board is dropped, be sure to document the drop in any reject report, and replace the system board.
• 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.
For access, remove these FRUs in order:
