Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when installing
DIMMs:
v IBM periodically makes updates available to provide enhancements to the
v To use the hot-add and hot-swap memory features, you must reconfigure your
v Your server operates with a minimum of two 512 MB DIMMs installed in slots 1
v Use the instructions in "Installing DIMMs" on page 21 to help maintain

the SMP board using the two captive mounting screws. Press firmly on the
screws and tighten them, alternating between them. Do not overtighten the
screws.
server. For details, see "Reinstalling an SMP Expansion Module and cover" on
page 23.
connect all external cables. For details, see "Installing the server in the rack
cabinet" on page 33.
When you install or remove microprocessors, the server configuration
information changes. Therefore, you must change and save the new
configuration information by using the Configuration/Setup Utility program. See
the User's Guide on the IBM xSeries Documentation CD.
Important: If your server will not start after replacing or installing a
microprocessor, you might have installed a microprocessor in the wrong socket
or installed a microprocessor of a different type, or the VRM is not seated
properly. Ensure that you have installed the microprocessor in the correct
location and that it is of the same type. Also ensure that the VRM is properly
seated in the slot.

mirroring and Memory ProteXion features of the Active Memory technology. Be
sure to check the IBM support Web site occasionally to ensure that you have the
most current levels of system software installed.

the IBM xSeries Documentation CD for additional information.
Note: The server must have a minimum of 4 GB of memory installed before you
can configure the hot-add memory feature.

list of memory modules for use with your server.
Note: For optimum performance, balance the amount of memory between the
two ports.
