8. Repeat steps 3 through 7 for each additional DIMM that you install.
9. Install the memory board:
a. Align the board in the guides over the memory connector.
b. Open the memory-board locking latches and insert the memory board into the
connector. Be sure that the locking latches snap into the closed position.
10. If you have other options to install or remove, do so now; otherwise, go to “Com-
pleting the installation” on page 19.
Attention: When you restart the server, the system displays a message indicating
that the memory configuration has changed.
• If you installed additional memory, start the Configuration/Setup Utility program
and select Save Settings.
• If the 3-3-3 beep code sounds during POST, the memory board may not be fully
seated. In some memory configurations, if the 3-3-3 beep code is followed by a
blank display screen and the Boot Fail Count feature in the Start Options of the
Configuration/Setup Utility is set to Enabled (its default setting), you must restart
the server three times to force the system BIOS to reset the memory connector or
bank of connectors from Disabled to Enabled.
Installing a microprocessor
The server comes with a minimum of one microprocessor installed on the system
board and supports up to four microprocessors. With more than one microprocessor,
the server can operate as a symmetric multiprocessing (SMP) server. With SMP, cer-
tain operating systems and application programs can distribute the processing load
among the microprocessors.
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. The most cur-
rent level of BIOS code for the server is available through the World Wide Web at
http://www.ibm.com/pc/support.
• 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 when you install a
microprocessor, use a microprocessor that has the same cache size and type, clock
speed, and internal and external clock frequencies as the microprocessor already
installed.
Notes:
1. To order additional microprocessor options, contact your IBM reseller or IBM mar-
keting representative.
2. The microprocessor in socket 1 is the startup (boot) microprocessor.
If you want to install additional microprocessors, populate the microprocessor sockets
in numeric order, starting with socket 2. The following illustration shows the locations
of the microprocessor sockets and VRMs on the system board.
Note: If you install the microprocessors in the wrong order, the server will not power
on.
