Note: When you restart the server, the system displays a message indicating that
Installing an additional microprocessor
Your server comes with one microprocessor installed on the system board. Your
server supports up to four microprocessors. If you install at least one additional
microprocessor, your 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.
If you need to remove a microprocessor, see "Microprocessor removal" on page
117.
Before you begin:
v Review the information in "Before you begin" on page 39, "Handling
v Thoroughly review the documentation that comes with the microprocessor, so
b. Align the hole on the front of the air baffle over the corresponding
alignment pin on the chassis; then, lower the air baffle into place.
Note: The alignment pin is located near the plastic fastener behind fan 1.
c. Press firmly on the two plastic fasteners until they snap into place on the
front of the air baffle. This secures the air baffle in the server.

the memory configuration has changed.
v If you installed additional memory, the Configuration/Setup Utility program
automatically saves the new configuration information.
v If you just replaced a failed DIMM, you must start the Configuration/Setup
Utility program, select Advanced Setup, select Memory Settings,
highlight the DIMM or pair or quad of DIMMs that you want to enable, and
then select Enable (see "Starting the Configuration/Setup Utility program"
on page 11).
v In some memory configurations, the 3-3-3 beep code might sound during
POST followed by a blank display screen. If this occurs and the Boot Fail
Count feature in the Start Options menu of the Configuration/Setup Utility
program is set to Enabled (its default setting), you must restart the server
three times to force the system BIOS to reset the DIMM or pair or quad of
DIMMs from Disabled to Enabled.
If this procedure does not enable the DIMMs, either the memory board or
at least one DIMM is improperly seated, or a memory component has
failed. Verify that the memory board and all the DIMMs are properly
seated. If the memory board or a DIMM is improperly seated, remove and
correctly reinstall it. If all of these components are properly seated, check
the memory-board VRM LED on the system board (see "System-board
LED locations" on page 47 for the LED location). If the memory-board
VRM LED is on or the problem remains, see "Diagnostic programs and
error messages" on page 28.

that you can determine whether you need to update the server BIOS code. The
latest level of BIOS code for your server is available through the World Wide
Web (see "Recovering the BIOS code" on page 37).
