54 Hardware Maintenance Manual: xSeries 330
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
5. Install the DIMM in the connector.
Attention: To prevent damage to the DIMM connectors do not force the memory
module into the connector.
a. Turn the DIMM so that the index slots align correctly with the connector.
Note: The DIMM has two index slots, one in the center and the other on the
left half of the DIMMS connector edge.
b. Insert the DIMM into the connector by pressing on both corners of the DIMM
at the same time. Be sure to press straight into the connector.
c. When installing a memory module be sure that no gap exists between the
DIMM and the retaining clips. If a gap does exist between the memory
module and the retaining clips: open the retaining clips, remove the DIMM;
then, reinsert the DIMM properly.
Note: It is a good idea to install or remove any other options at this time.
6. Turn on the server.
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 you just replaced a failed DIMM, you must start the Configuration/Setup
Utility program, select Advanced Setup, select Memory Settings, highlight
the connector or bank of connectors that you want to enabled, and then select
Enable.
• 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 of the Configuration/Setup Utility is set to
Enabled (its default setting), you must restart the server three times (a "three-
boot reset") to force the system BIOS to reset the memory connector or bank of
connectors from Disabled to Enabled.
