Installing a microprocessor
This section describes how to install a microprocessor in the server. Before you
install a microprocessor, review the following information:
v The server comes with one microprocessor installed. The following illustration
v If one microprocessor is installed:
v If you install a second microprocessor in the server:
Notes:
1. Read the documentation that comes with the microprocessor to determine if you
2. To use SMP, obtain an SMP-capable operating system (optional). For a list of

regulator module (VRM) slot on the system board. (The VRM for microprocessor
1 is integrated on the system board.)

– The microprocessor is installed in microprocessor socket 1 (U82).
– The microprocessor supports both the startup and application processes.
– The server operates as a symmetric multiprocessing (SMP) server. With an
SMP, operating system application programs can distribute the processing
load between the microprocessors. This enhances performance for database
and point-of-sale applications, integrated manufacturing solutions, and other
applications.
– Microprocessor 1 is installed in microprocessor socket 1 (U82);
microprocessor 2 is installed in socket 2 (U121).
