Installing memory modules - IBM eServer xSeries 220

Content

Adding memory to the server is an easy way to make programs run faster. You can increase the amount of memory in the server by installing options called memory-module kits . Each kit contains one industry-standard, dual in-line memory module (DIMM). The server uses a noninterleaved memory configuration. The server comes with a dual in-line memory module (DIMM) that is installed on the system board in DIMM slot 1 (connector J19).

Notes:

1. When installing additional memory modules, install the second memory module in the connector labeled DIMM3 (J23), the third in DIMM2 (J21), and the fourth in DIMM4 (J26).
2. The xSeries 220 server supports 128 MB, 256 MB, 512 MB , and 1 GB DIMMs. These DIMMs can be installed in any memory slot. The server supports a minimum of 128 MB and a maximum of 4GB of system memory. Click here review a list of supported memory modules.
3. Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a DIMM, you must save the new configuration information by using the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings.

Attention: When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity.
For details on handling these devices, see 'Handling electrostatic discharge-sensitive devices'.

To install a DIMM, complete the following steps:

1. Review the documentation that comes with the option.
2. Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the cover
3. Select the connector in which to install the DIMM.
4. Touch the static-protective package containing the DIMM to any unpainted metal surface on the server. Then, remove the DIMM from the package.
   
   Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently.
   
   
   1. Open the retaining clips on the connector.
   2. Turn the DIMM so that the pins align correctly with the connector.
   3. Insert the DIMM into the connector by pressing on one edge of the DIMM and then on the other edge of the DIMM. Ensure that you press straight into the connector.
   4. Make sure that the retaining clips are in the closed position. If a gap exists between the DIMM and the retaining clips, the DIMM has not been properly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert the DIMM.
      
      
5. If you have other options to install or remove, do so now; otherwise, go to 'Installing the cover'.

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 enable, then select Enable.
• In some memory configurations, the 3-3-3 beep code might sound during POST followed by a blank screen. If this occurs, 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.
