DIMMs 1 through 16, but access is through microprocessor 1. This is important
if load balancing is a necessity for your operating system or software load.
To install an additional microprocessor and heat sink, complete the following steps:
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 263.
1. Read the safety information that begins on page "Safety" on page vii and
"Installation guidelines" on page 261.
2. Install the microprocessor:
a. Remove the static-protective bag, and the foam surrounding the bag, from
the box.
b. 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.
c. If there is a plastic protective cover on the bottom of the microprocessor,
carefully remove it.
d. Twist the handle of the microprocessor installation tool counterclockwise so
that it is in the open position.
Note: If you are installing E7 series microprocessors in your server, you
must use the microprocessor installation tool with the text "X7500 + E7" on
the bottom of the tool (see the following illustration). Tools that do not have
