Memory
Adding memory to your server is an easy way to improve system performance. You
can increase the amount of memory in your server by installing options called
memory-module kits. Each kit contains one industry-standard, dual-in-line memory
module (DIMM). Your server uses a noninterleaved memory configuration, which
enables you to add, remove, or replace one DIMM at a time. In an interleaved system
you would have to add, remove, or replace memory in sets.
Your server comes with a dual in-line memory module (DIMM) installed on the
system board in DIMM connector 1.
Complete the following steps to install a DIMM:
Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, refer to
“Handling static-sensitive devices” on page 38.
1. Review the information in “Safety information” on page 39.
2. Turn off the server and peripheral devices.
3. Remove all external cables from the server; then, remove the server from the rack
and remove the cover. For more information see “Removing the cover” on page
44 for instructions.
4. If necessary, remove the PCI card in slot 2 for easier access to the DIMM
connectors.
5. Touch the static-protective bag 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.
