2. Lift the hinged microprocessor-bracket frame into an open position and remove the microprocessor
dust cover, tape, or label from the surface of the microprocessor socket, if one is present. Store the
dust cover in a safe place.
3. Touch the static-protective package that contains the new microprocessor to any unpainted metal
surface on the node; then, remove the microprocessor from the package.
v
Do not touch the microprocessor contacts; handle the microprocessor by the edges only.
Contaminants on the microprocessor contacts, such as oil from your skin, can cause connection
failures between the contacts and the socket.
v
Handle the microprocessor carefully. Dropping the microprocessor during installation or removal
can damage the contacts.
v
Do not use excessive force when you press the microprocessor into the socket.
v
Verify that the microprocessor is oriented, aligned, and positioned in the socket before you try to
close the lever.
4. To align the microprocessor with the socket, use the triangular alignment cutout on the
microprocessor socket and the triangular alignment mark (
4
in Figure 252 on page 230) on the
microprocessor. Also use the position of the notches to align the microprocessor.
5. After alignment, carefully place the microprocessor onto the socket. Close the microprocessor-bracket
frame (
3
).
Tip: Do not force the microprocessor. The microprocessor fits only one way on the socket.
