Installing A Microprocessor - IBM 8862 - Eserver xSeries 365 Maintenance And Troubleshooting Manual

Installing a microprocessor

The following notes describe information that you must consider when installing a
microprocessor in the server:
v The server comes with a minimum of one microprocessor installed on the
v If one microprocessor is installed:
v If you install additional microprocessors in the server, microprocessor 2 is
v A new microprocessor comes in a kit with a VRM and a heat sink. The VRM is

microprocessor board in the microprocessor tray 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. This enhances performance for database and point-of-sale
applications, integrated manufacturing solutions, and other applications. The
following illustration shows the microprocessor connectors and the
microprocessor voltage regulator module (VRM) connectors on the
microprocessor tray assembly.
Note: The voltage regulators for microprocessors 1 and 2 are integrated on the
microprocessor tray assembly; the VRMs for microprocessors 3 and 4
come with the microprocessor options and must be installed on the
microprocessor tray assembly.
