Lenovo ThinkServer TD200x - Manual (Page 108)

2 Microprocessor 2
Attention:
1. A startup (boot) microprocessor must always be installed in microprocessor
socket 1 on the system board.
2. To ensure correct server operation when you install an additional
microprocessor, use microprocessors that are compatible and install at least one
DIMM in a DIMM connector for microprocessor 2 (starting with the connector
farthest from the microprocessor). (See “Installing a memory module” on page
85 for more information.)
To install a microprocessor, do the following:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 37.
2. Turn off the server and peripheral devices; then, disconnect the power cords
and all external cables. Remove the left-side cover (see “Removing the
left-side cover” on page 42 for more information).
3. Remove the hot-swap power supplies from the server.
4. Open the power-supply cage (see“Opening the power-supply cage” on page
47 for more information).
5. Remove the air baffle (see “Removing the air baffle” on page 58 for more
information).
6. Locate the second microprocessor socket on the system board.
Attention: The microprocessor retention latch is spring-loaded when the
microprocessor is in place. Releasing the latch too quickly or allowing it to
spring upward can damage the microprocessor and surrounding components.
7. Release the microprocessor retention latch by pressing down on the end,
moving it to the side, and slowly releasing it to the fully open (up) position.

8. Open the microprocessor bracket frame by lifting up the tab on the top edge.
Attention:
a. 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.
b. Handle the microprocessor carefully. Dropping the microprocessor during
installation or removal can damage the contacts.
c. Do not use excessive force when you press the microprocessor into the
socket.
