b. 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.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling these
devices, see “Handling static-sensitive devices” on page 48.
c. 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:
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
Make sure that the microprocessor is oriented and aligned and positioned
in the socket before you try to close the lever.
d. Align the microprocessor with the socket (note the alignment mark and the
position of the notches); then, carefully place the microprocessor straight
down on the socket and close the microprocessor bracket frame.
Attention: The microprocessor fits only one way on the socket. You must
place a microprocessor straight down on the socket to avoid damaging the
pins on the socket. The pins on the socket are fragile. Any damage to the
pins may require replacing the system board.
