Installing a microprocessor and heat sink:
For information about the type of microprocessor
that the server supports and other information that you must consider when you install a
microprocessor, see the
Installation and User’s Guide
on the HUAWEI
Documentation
CD.
Read the documentation that comes with the microprocessor to determine whether you must
update the HUAWEI Tecal Server Firmware.
Important:
A startup (boot) microprocessor must always be installed in microprocessor socket 1 on
the microprocessor board.
To ensure correct server operation, be sure to use microprocessors that are compatible
and install a memory card and an additional DIMM for microprocessor 2. Compatible
microprocessors must have the same QuickPath Interconnect (QPI) link speed,
integrated memory controller frequency, core frequency, power segment, cache size, and
type.
Microprocessors with different stepping levels are supported in this server. If you install
microprocessors with different stepping levels, it does not matter which microprocessor
is installed in microprocessor socket 1 or socket 2.
If you are installing a microprocessor that has been removed, make sure that it is paired
with its original heat sink or a new replacement heat sink. Do not reuse a heat sink from
another microprocessor; the thermal grease distribution might be different and might
affect conductivity.
If you are installing a new heat sink, remove the protective backing from the thermal
material that is on the underside of the new heat sink.
If you are installing a new heat-sink assembly that did not come with thermal grease, see
“Thermal grease” for instructions for applying thermal grease; then, continue with step 1
of this procedure.
If you are installing a heat sink that has contaminated thermal grease, see “Thermal
grease” for instructions for replacing the thermal grease; then, continue with step 1 of
the following procedure.
To install a new or replacement microprocessor, complete the following steps.
Step 12
Touch the static-protective package that contains the microprocessor to any unpainted metal
surface on the server. Then, remove the microprocessor from the package.
Step 13
Open the microprocessor release latch
by pressing down on the end, moving it to the
side, and releasing it to the open (up) position. Swing open the microprocessor retainer
bracket
