## Increase System Memory With Additional DIMMs

This is a cold service procedure that can be performed by customers.

You should be familiar with the memory configuration guidelines described in DIMM Population Rules before adding new DIMMs to increase a server's memory capacity.

| Caution - You must disconnect the power cables from the system before performing this procedure.

1. Consider your first steps:

   - Familiarize yourself with DIMM configuration rules.

     See DIMM Population Rules.

     See Supported DIMM Configurations

     See DIMM Rank Classification Labels.

   - Prepare the server for service.

     See Preparing for Service

2. Confirm that the DIMMs in the upgrade kit are compatable with the DIMMs already installed in the server.

   Note - DIMM architectures must be identical (same capacity, same rank classification label). See DIMM Rank Classification Labels.

3. Unpack the new DIMMs and place them on an antistatic mat.
4. Swing the air duct up and forward to the fully open position.
5. At a DIMM slot that is to be upgraded, open the ejector tabs and remove the filler panel.

   Do not dispose of the filler panel. You may want to reuse it if any DIMMs are removed at another time.

6. Align the notch on the bottom edge of the DIMM with the key in the connector.

   | Caution - Ensure that the orientation is correct. The DIMM might be damaged if the orientation is reversed.

7. Press the DIMM into the connector until the ejector tabs lock the DIMM in place.

   Figure 45 Installing DIMMs

   Note - If the DIMM does not easily seat into the connector, do not try to force it into position. Instead, check its orientation. If the orientation is not correct, forcing the DIMM into the connector is likely to damage the DIMM, or the connector, or both.

8. Repeat Step 5 through Step 7 until all DIMMs are installed.
9. Finish the installation procedure:

   - Return the server to operation.

     See Returning the Server to Operation.

   - Verify DIMM functionality.

     See Verify DIMM Functionality.
