2. Record the cable routing and cable connections, and then disconnect all cables from the system board.
See "System board" on page 51.
Removal steps
Notes:
• Ensure that a new VRM heat sink is installed when you install the system board. If the new system board
does not come with a VRM heat sink, see "VRM heat sink" on page 105 to install one first.
• The failing system board must be returned with a microprocessor socket cover to protect the pins during
shipping and handling.
Microprocessor socket cover installation procedure
1. After you have removed the microprocessor from the failing system board, close the microprocessor
retainer. Then, put the lever to the locked position to secure the retainer in place.
2. Note the orientation of the socket cover, and install one side of the socket cover into the microprocessor
socket. Carefully press the other side of the socket cover downward until the socket cover snaps into
position.
Note: The microprocessor socket cover might look slightly different from the illustration.
