Installing Microprocessors
Installing Microprocessors
When you install an additional microprocessor, your Netfinity 5000 server can
operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating
systems and application programs can distribute the processing load between
microprocessors. This enhances performance for database and point-of-sale
applications, integrated manufacturing solutions, and other applications.
Installing Microprocessor Upgrades
Your server comes with an Intel Pentium II microprocessor. This microprocessor
incorporates MMX technology with built-in ECC level two (L2) cache. For the latest
information about microprocessor upgrades available for your server, contact your
IBM reseller, IBM marketing representative, or see
http://www.pc.ibm.com/us/compat/ on the World Wide Web. If you do upgrade the
microprocessor, use the instructions that come with the upgrade along with the
instructions in “Installing or Replacing a Microprocessor” on page 67.
Attention:
If you install an additional microprocessor that is different from the currently
installed microprocessor, your server operation might be unreliable. To prevent
this, use a microprocessor with the same internal and external clock speed,
and the same cache size and voltage requirements as those of the currently
installed microprocessor. Microprocessor internal and external clock
frequencies and cache size must be identical.
The voltage-regulator module (VRM) for the additional microprocessor plugs
into a connector on the system board (see “System Board Connectors” on
page 169 for the location of the VRM connector). Because each
microprocessor has specific power and voltage requirements, be sure to use
the VRM that comes with the microprocessor.
Note: The voltage regulator function for the microprocessor that is shipped
with your server is built into the system board.
If you select a setting for the frequency switch that is greater than the actual
frequency of the microprocessor, you might damage the microprocessor. The
frequency switch settings are shown in Table 3 on page 70.
For additional information about microprocessor speeds, clock frequencies, and
jumper settings, see Chapter 7, “Server Records and Specifications” on page 161.
