xSeries 445 Type 8870: Option Installation Guide
6. Remove the SMP Expansion Module in which you plan to install the
microprocessor; then, remove the module cover and determine the socket
where the microprocessor is to be installed. For details, see "Removing and
Installing the SMP Expansion Module and cover" on page 32.
7. Determine which type of microprocessors are installed in your server. The
easiest way to do this is by the locations of the installed microprocessors in
the SMP Expansion Module. If the microprocessors are installed only in
connectors 1 and 4, your server came with Intel Xeon DP microprocessors. If
the microprocessors are installed in any other connectors, such as 1 and 2 or
1,2, and 3, your server came with Intel Xeon MP microprocessors.
Note: If your server contains only one SMP Expansion Module, remove the
SMP baffle above it to gain access to the module. If your server
contains two SMP Expansion Modules, remove the top module to gain
access to the bottom or lower SMP Expansion Module.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details on handling these devices, see
"Handling static-sensitive devices" on page 10.
8. If you are installing a new microprocessor, go to step 9; otherwise, continue:
a. Verify that you have selected the correct microprocessor to be replaced.
The LED beside the failing microprocessor will be lit.
Attention: Before attempting to remove the heat sink from the
microprocessor, note that the heat-conducting grease between the heat
sink and the microprocessor might have formed a strong bond. Do not
force the components apart; doing so can damage the microprocessor
pins. If the heat sink does not separate from the microprocessor easily,
loosen one heat sink captive mounting screw first. This allows one corner
of the heat sink to be lifted off of the microprocessor; then, you can loosen
the other captive mounting screw and remove the heat sink.
