Install a DIMM

DIMMs are cold-service components that can be replaced by customers. For the location of the DIMMs, see Processor Module Components.

1. Consider your first steps.
   • Familiarize yourself with DIMM population rules.

     See Understanding DIMM Configurations

   • Prepare the system for service.

     See Preparing for Service.

   • Remove the processor module. Place the processor module on an ESD-protect work surface.

     See Remove a Processor Module or Processor Filler Module.

2. Consider your next steps.
   • If you are replacing a faulty DIMM, ensure that you have removed the faulty DIMM.

     See Identifying Faulty DIMMs.

     See Remove a DIMM.

   • If you are adding DIMMs to a half-populated processor module:

     Ensure you have the correct DIMMs for your server. See Identifying DIMMs.

   • If you are populating a new processor module:

     Ensure you have the correct DIMMs for your server. See Understanding DIMM Configurations.

3. Unpack the replacement DIMMs and place them on an antistatic mat.
4. Ensure that the ejector tabs on the connector that will receive the DIMM are in the open position.
5. Align the DIMM notch with the key in the connector.

6. Push the DIMM into the connector until the ejector tabs lock the DIMM in place.

   If the DIMM does not easily seat into the connector, check the DIMM's orientation.

7. Repeat Step 4 through Step 6 until all new DIMMs are installed.
8. Place the cover onto the processor module and slide the cover forward until the latch clicks into place.
9. Consider your next steps.
   • If you are adding a second processor module to the server, return to Server Upgrade Process.
   • If you are replacing a processor module after installing replacement DIMMs, proceed to Step 10.
10. Finish the installation procedure.
