3.14 How to Replace the Main Logic Board
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:
Section 3.13 “How to Remove the Main Logic Board” on page 116
Caution - 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.
Caution - Perform this procedure on a workbench. Sun Microsystems does not
support changing the main logic board while the system is installed in a rack.
Caution - 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.
Be sure to complete this task before starting the procedure:
Section 2.1 “How to Power Off the System” on page 54
3.14.2 What to Do
1. Remove the main logic board from its antistatic packaging and place it on an
antistatic mat.
Caution - Handle the main logic board by the back panel or edges only.
2. Set the jumper settings on the replacement main logic board so that they match
the jumper settings on the original main logic board.
