Install a DIMM

Language:

Ensure that the replacement DDR4 DIMM matches the size of the DIMM it is replacing.

Install a DIMM.
1. Ensure that the ejector tabs are in the open position.
2. Align the notch in the replacement DIMM with the connector key in the connector socket.
  The notch ensures that the DIMM is oriented correctly.
3. Push the DDR4 DIMM into the connector until the ejector tabs lock the DIMM in place.
  If the DIMM does not easily seat into the connector socket, verify that the notch in the DIMM is aligned with the connector key in the connector socket. If the notch is not aligned, damage to the DIMM might occur.
  
  Note - If you want to move a faulty DDR4 DIMM to a new DIMM socket or re-seat a DIMM for troubleshooting, you must first manually clear the associated DIMM fault. Otherwise, the DIMM fault might follow the DIMM to the new socket location or reoccur on the current socket location, possibly causing a false DIMM fault condition.

Return the controller to operation.
1. Install the controller top cover.
  See Install the Controller Top Cover.
2. Close the fan door.
3. Return the controller to the normal rack position.
  See Return the Controller to the Normal Rack Position.
4. Reconnect the power cords to the controller power supplies and reconnect the data cables.
  See Reconnect Data Cables and Power Cords.
5. Power on the controller.
  See Power On the Controller.
  
  Verify that the Power/OK status indicator is steady on.
Go to the Maintenance > Hardware screen of the BUI. Click the right-arrow icon for the controller, click DIMM, and verify that the status icon is green for the newly installed DIMM. To view details about the new DIMM, click its information icon.

(Optional) Use Oracle ILOM to clear controller DDR4 DIMM faults.
DDR4 DIMM faults are automatically cleared after a new DIMM has been installed. If you need to manually clear DDR4 DIMM faults, refer to the Oracle Integrated Lights Out Manager (ILOM) 3.2 Documentation Library at http://www.oracle.com/goto/ILOM/docs.
