IBM System x3550 M3, Installation And User Manual

Page: 101 / 160

v
The server supports up to two Intel Xeon multi-core microprocessors. See
http://www.ibm.com/servers/eserver/serverproven/compat/us/ for a list of
supported microprocessors.
v Do not install an Intel Xeon
™
5500 series microprocessor and an Intel Xeon
™
5600 series microprocessor in the same server.
v
Do not mix dual-core, quad-core, and six-core microprocessors in the same
server.
v
The first microprocessor must always be installed in microprocessor socket 1 on
the system board.
v When one microprocessor is installed, a heat sink filler is not required for
microprocessor socket 2, however, the microprocessor 2 air baffle, the sixth fan,
and the DIMM air baffle must be installed to provide proper system cooling.
v
Do not remove the first microprocessor from the system board when you install
the second microprocessor.
v When you install the second microprocessor, you must also install additional
memory and the sixth fan. See “Installing a memory module” on page 56 for
details about the installation sequence.
v
To ensure proper server operation when you install an additional microprocessor,
use microprocessors that have the same QuickPath Interconnect (QPI) link
speed, integrated memory controller frequency, core frequency, power segment,
internal cache size, and type.
v
Mixing microprocessors of different stepping levels within the same server model
is supported.
v When mixing microprocessors with different stepping levels within the same
server model, you do not have to install the microprocessor with lowest stepping
level and features in microprocessor socket 1.
v
Both microprocessor voltage regulator modules are integrated on the system
board.
v
If you have to replace a microprocessor, call for service.
v Read the documentation that comes with the microprocessor to determine
whether you have to update the UEFI firmware. To download the most current
level of UEFI firmware for the server, go to http://www.ibm.com/support/fixcentral/.
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 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. For details, see the information about
thermal grease in the
Problem and Determination Service Guide .
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal
grease.
v To order an additional optional microprocessor, contact your IBM marketing
representative or authorized reseller.
To install an additional microprocessor and heat sink, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 44.
2. Turn off the server and peripheral devices and disconnect the power cords and
all external cables (see “Turning off the server” on page 32).
