second microprocessor. Use the BIOS Setup Utility program to determine the
type and speed of the microprocessor that is currently installed in the server.
v The server supports up to two microprocessors. If the server comes with one
microprocessor, you can install a second microprocessor.
v Both microprocessors must have the same cache size and type, front-side bus
frequency, and the same clock speed. Microprocessor internal and external clock
frequencies must be identical.
v Read the documentation that comes with the microprocessor to determine
whether you must update the basic input/output system (BIOS) code for the
server. To download the most current level of BIOS code and many other code
updates for your server, go to http://www.ibm.com/systems/support/, select
System x3610 from the Hardware list, and click the Download tab.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and optional devices, go to http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
v To order additional microprocessors, contact your IBM marketing representative
or authorized reseller.
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.
The following illustration shows the microprocessor connector locations on the
system board.
