– Intel Xeon EX versions of the 6000 and 7000 Series microprocessors are
supported only on machine types 7145 and 7146.
– Intel Xeon EX E7 Series microprocessors are supported only on machine types
7143 and 7191.
v 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.
v Because of space limitations, you must use the microprocessor tool that comes
with the microprocessor, when you install the microprocessor.
v Read the documentation that comes with the microprocessor to determine
whether you have to update the UEFI firmware (server firmware). To download
the most current level of UEFI firmware, go to http://www.ibm.com/systems/
support/.
v Obtain an SMP-capable operating system. For a list of supported operating
systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.
v You can use the Setup utility to determine the specific type of microprocessor in
the server.
v Microprocessor sockets must always contain either a heat-sink blank or a
microprocessor and heat sink.
v Populate the microprocessor sockets in the following order: 1, 4, 2, and 3. The
following illustration shows the locations of the microprocessor sockets on the
microprocessor board.
Microprocessor 1
Microprocessor 2
Microprocessor 3
Microprocessor 4
Note: In a one node server only, if your server has more than two microprocessors
installed, you must install two QPI wrap cards in the server.
To install a microprocessor, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 38.
2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables as necessary to replace the device.
3. Remove the server top cover (see “Removing the top cover” on page 44).
