Working with microprocessors
Your server comes with one or two microprocessors installed. The following illustration
shows the location of the microprocessors on the system board of your server.
Servers with one microprocessor installed:
• Microprocessor is installed in microprocessor socket 1 (U47).
• Microprocessor supports both the startup and application processes.
• A terminator card is installed in microprocessor socket 2 (U79).
Servers with two microprocessors installed:
• One microprocessor is installed in microprocessor socket 1 (U47), and the
second microprocessor is installed in socket 2 (U79).
• Both microprocessors share the system load.
Attention: To avoid damage and to ensure proper server operation, review the
following before you install a microprocessor:
• Ensure that the microprocessors are the same type, have the same cache size,
have the same clock speed, and have the same stepping levels (revision levels).
To determine the stepping level, see the documentation that comes with the
microprocessor or contact the microprocessor manufacturer.
• Ensure that the microprocessor internal and external clock frequencies are
identical.
• See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of
microprocessors for use with your server.
