IBM 7379E2U, Installation And User Manual

Page: 105 / 152

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
79 for more information.)
To install a microprocessor, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 28.
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 48 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
55 for more information).
5. Remove the air baffle (see “Removing the air baffle” on page 51 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.
