Microprocessor 2
socket (CPU2)
v If only one microprocessor is installed, make sure that it is installed in
microprocessor socket 1 (system-board identifier CPU1). Microprocessor 1
supports both the startup and application processes.
v If you install a second microprocessor in the server, the server operates as a
symmetric multiprocessing (SMP) server, and 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 2 is installed in
socket 2 (system-board identifier CPU2).
v Read the documentation that comes with the microprocessor to determine
whether you must update the BIOS code in the server. To download the most
current level of BIOS code for your server, go to http://www.ibm.com/servers/
eserver/support/xseries/index.html and follow the instructions.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems, see http://www.ibm.com/servers/eserver/serverproven/compat/
us/.
