xSeries 440:Option Installation Guide
Installing and replacing a microprocessor
This section describes how to install and remove microprocessors and VRMs. Before
performing any of the procedures in this section, read “Safety” on page v, “Handling
static-sensitive devices” on page 10, and Before you begin.
Your xSeries 440 Server supports up to two Intel Xeon DP or four Intel Xeon MP
microprocessors in each SMP Expansion Module. With both SMP Expansion Modules
installed, the server can support a maximum of four Intel Xeon DP or eight Intel Xeon
MP microprocessors of the same type and speed.
Note: Do not install both Intel Xeon MP and Intel Xeon DP microprocessors in the
same server or SMP Expansion Module.
Before you begin:
• Read the documentation that comes with the microprocessor to determine if you
need to update the server basic input/output system (BIOS) code. For the most
current level of BIOS code for the server, go to http://www.ibm.com/pc/support/ on
the World Wide Web.
• Obtain an SMP-capable operating system (optional). For a list of supported oper-
ating systems, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web.
Attention: To avoid damage and ensure proper server operation after you install a
replacement or an additional microprocessor, use a microprocessor that has the same
cache size and type, clock speed, and internal and external clock frequencies as the
microprocessors already installed in the individual SMP Expansion Module. For a list
of microprocessors supported by your server, see the ServerProven list at
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
Notes:
1. To order additional microprocessor options, contact your IBM marketing represen-
tative or authorized reseller.
2. The microprocessor in socket 1 of the bottom SMP Expansion Module is the star-
tup (boot) microprocessor.
3. If you are adding additional Intel Xeon MP microprocessors to an SMP Expansion
Module, populate the empty microprocessor sockets in numeric order, starting
with socket 1. If you install the microprocessors in the wrong order, the server will
not power on.
4. If you are adding additional Intel Xeon DP microprocessors to your server, you
must have a second unpopulated SMP Expansion Module. Server models that
come with Intel Xeon DP microprocessors support a maximum of two micropro-
cessors per SMP Expansion Module, and are installed in microprocessor sockets
1 and 4.
The following illustration shows the locations of the startup microprocessor and its
VRM on the system board. It also shows the microprocessor baffles and the VRM
slots for the other microprocessor sockets.
