IBM 7383, Installation And Service Manual

v
When two microprocessors are installed, the air baffle and fan 2 must be
installed to provide proper system cooling.
v
When you install the second microprocessor, you must also install additional
memory, the air baffle, and fan 2. See “Memory module installation” on page 59
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
Read the documentation that comes with the microprocessor to determine
whether you have to update the server firmware. To download the latest level of
server firmware and other code updates 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 more information about applying or
working with thermal grease, see “Thermal grease” on page 89.
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.
v
Do not remove the first microprocessor from the system board to install the
second microprocessor.
v
To order an additional optional microprocessor, contact your IBM sales
representative or IBM reseller.
Read the safety information in “Safety” on page vii and “Installation guidelines”
on page 34.
If you are replacing a component or installing an optional device in the server, you
need to turn off the server and peripheral devices, and disconnect the power cords
and all external cables.
About this task
To install a microprocessor and heat sink, complete the following steps.
Procedure
1. Carefully turn the server on its side so that it is lying flat, with the cover
facing up.
Attention:
Do not allow the server to fall over.
2. Unlock and remove the left-side cover (see “Removing the left-side cover” on
page 39).
3.
Remove the air baffle (see “Removing the air baffle” on page 210).
4. Rotate the heat sink retention module release lever to the open position.
