code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2100 SDRAM Registered DIMM specification, which is available from http://www.jedec.org/. For a current list of supported options for the blade server, see the ServerProven list at http://www.ibm.com/pc/us/compat/. 8. PC2100 DIMMs are backward-compatible and work in the PC1600 sockets. 9. Installing or removing DIMMs changes the configuration information for the blade server. Therefore, after installing or removing a DIMM, you must change and save the new configuration information by using the Configuration/Setup Utility program. When you restart the blade server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings (see "Configuration/Setup Utility menu choices" on page 14).

DIMM socket locations Before you begin, read the documentation that comes with the option. Complete the following steps to install a DIMM: 1. Review Appendix B, "Safety information," on page 97 and "Installation guidelines" on page 27. 2. Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter unit (see "Removing the blade server from the BladeCenter unit" on page 29). 3. Carefully lay the blade server on a flat, static-protective surface. 4. Open the blade server cover (see "Opening the blade server cover" on page 34). 5. Locate the DIMM connectors on the system board. Determine the connectors into which you will install the DIMMs (see note 3 on page 39.). 6. Touch the static-protective package that contains the DIMM option to any unpainted metal surface on the BladeCenter unit or any unpainted surface on any other grounded rack component for at least two seconds. Then, remove the DIMM from the package. 7. To install the DIMMs, repeat the following steps for each DIMM that you install: 40 BladeCenter HS20 Type 8832: Hardware Maintenance Manual and Troubleshooting Guide
