Installing a microprocessor

The server comes with a minimum of one microprocessor installed on the system
board and supports up to four microprocessors. With more than one microprocessor,
the server can operate as a symmetric multiprocessing (SMP) server. With SMP,
certain operating systems and application programs can distribute the processing
load among the microprocessors.
Before you begin:

Attention: To avoid damage and ensure proper server operation when you install a
replacement or an additional microprocessor, use a microprocessor that has the same
cache size and type, clock speed, and internal and external clock frequencies as the
microprocessors already installed.
Notes:
1. To order additional microprocessor options, contact your IBM reseller or IBM
2. The microprocessor in socket 1 is the startup (boot) microprocessor.
If you want to install additional microprocessors, populate the microprocessor sockets
in numeric order, starting with socket 2. The following illustration shows the locations
of the microprocessor sockets and VRMs on the system board.
Note: If you install the microprocessors in the wrong order, the server will not power
If you just replaced a failed DIMM, you must start the Configuration/Setup Utility
program, select Advanced Setup, select Memory Settings, highlight the
connector or bank of connectors that you want to enable, and then select Enable.
If the 3-3-3 beep code sounds during POST, the memory board might not be fully
seated. In some memory configurations, if the 3-3-3 beep code is followed by a
blank display screen, and the Boot Fail Count feature in the Start Options of the
Configuration/Setup Utility is set to Enabled (its default setting), you must restart
the server three times to force the system BIOS to reset the memory connector or
bank of connectors from Disabled to Enabled.
Read the documentation that comes with the microprocessor to determine if you
need to update the server basic input/output system (BIOS) code. The most
current level of BIOS code for the server is available through the World Wide Web
at http://www.ibm.com/pc/support.
Obtain an SMP-capable operating system (optional). For a list of supported
operating systems, go to http://www.ibm.com/pc/us/compat/ on the World Wide
Web.
