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 clock speed. Microprocessor internal and external clock
frequencies must be identical.
v When you install a microprocessor in microprocessor connector 2, you must also
install the voltage regulator module (VRM), which comes with the microprocessor,
in the VRM connector.
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, complete the following steps:
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click System x.
3. Under Popular links, click Software and device drivers.
4. Click System x3650 to display the matrix of downloadable files for the server.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and optional devices, see http://www.ibm.com/servers/eserver/
serverproven/compat/us/.
v To order additional microprocessor optional devices, 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.
See "System-board optional-device connectors" on page 17 for the location of the
microprocessor connectors and the VRM connector.
The following illustration shows how to install the second microprocessor on the
system board.
