Removing and installing components
Recommended tools
The procedures in this document may require the following tools:

Screw list
NOTE: When removing screws from a component, it is recommended to note the screw type, the quantity of screws,
and then place them in a screw storage box. This is to ensure that the correct number of screws and correct screw type
is restored when the component is replaced.
NOTE: Some systems have magnetic surfaces. Ensure that the screws are not left attached to such surface when
replacing a component.
NOTE: Screw color may vary with the configuration ordered.
