Installing DIMMs

DIMMs must be installed in groups of four, referred to as a row.

CAUTIONS

• Use extreme care when installing a DIMM. Applying too much pressure can

damage the connector. DIMMs are keyed and can be inserted in only

one way.

• Mixing dissimilar metals might cause memory failures later, resulting in data

corruption. Install DIMMs with gold-plated edge connectors only.

• The system does not support mixed-sized DIMMs or DIMMs from different

vendors within the same row.

1. Power down the system by pressing and holding the power button on the front panel for several

seconds.

2. Unplug both AC power cords to remove standby power from the server.

3. See the warnings and cautions under Removing and Installing the Top Cover.

4. Follow the instructions under Removing the Top Cover.

5. Remove the PCI riser card assembly. For instructions, see Removing the PCI Riser Assembly.

6. Gently push the plastic ejector levers out and down to open the DIMM slots.

7. Hold the DIMM only by its upper edges, being careful not to touch its components or gold edge

connectors. Carefully insert the DIMM into the connector. Firmly press down on the DIMM

until the latches engage.

8. Repeat steps 6 and 7 to install each additional DIMM in the row.

9. Follow the instructions under Installing the Top Cover.
