5. Touch the static-protective package that contains the new microprocessor to
any unpainted metal surface on the server; then, remove the microprocessor
from the package.
Attention:
Dropping the microprocessor during installation or removal can
damage the contacts. Also, contaminants on the microprocessor contacts, such
as oil from your skin, can cause connection failures between the contacts and
the socket.
6. Position the microprocessor over the microprocessor socket. Use the triangular
alignment cutout on the microprocessor socket and the triangular alignment
mark on the microprocessor to assist you in aligning the microprocessor to the
socket. Then, carefully place the microprocessor into the socket. Do not force
the microprocessor, it only fits one way onto the socket.
