3.14.1 Before You Begin

All removable components should have been removed from the old main logic board prior to removing the board from the system. You can transfer the components to the replacement board after it is installed in the system. For more information, see:

• "3.13 How to Remove the Main Logic Board"

Use an antistatic mat when working with the main logic board. An antistatic mat provides the cushioning required to protect the board, to prevent the main logic board from flexing, and to provide antistatic protection.

Perform this procedure on a workbench. Sun Microsystems does not support changing the main logic board while the system is installed in a rack.

Do not attempt to install components on the main logic board while it is outside the system. Doing so can damage the main logic board.
