v The microprocessor speeds are automatically set for this server; therefore, you
do not have to set any microprocessor frequency-selection jumpers or switches.
v If you have to replace a microprocessor, call for service.
v If the thermal-grease protective cover (for example, a plastic cap or tape liner) is
removed from the heat sink, do not touch the thermal grease on the bottom of
the heat sink or set down the heat sink.
v Do not remove the first microprocessor from the system board to install the
second microprocessor.
Attention:
v A startup (boot) microprocessor must always be installed in microprocessor
socket 1 on the system board.
v 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.
To install an additional microprocessor, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 35.
2. Turn off the server and disconnect all power cords and external cables (see
“Turning off the server” on page 24).
3. Remove the server top cover (see “Removing the server top cover” on page
44).
4. If you have the optional hot-swap rear hard disk drive cage installed, rotate it
up (see “Rotating the optional hot-swap rear hard disk drive cage up” on page
46).
5. Remove the PCI riser-card assembly (see “Removing the PCI riser-card
assembly” on page 46).
6. Remove the air baffle (see “Removing the air baffle” on page 49).
7. Locate the second microprocessor socket on the system board (see
“System-board internal connectors” on page 28).
8. Release the microprocessor release lever by pressing down on the end,
moving it to the side, and releasing it to the open (up) position.
9. Open the microprocessor bracket frame by lifting up the tab on the top edge.
Keep the bracket frame in the open position.
Attention: Do not touch the connectors on the microprocessor and the
microprocessor socket.
10. The microprocessor is preinstalled in the installation tool, release the sides of
the cover and remove the cover from the installation tool.
11. Install the microprocessor:
