Install a DIMM

  1. Unpack the replacement DDR4 DIMM and place it on an antistatic mat.
  2. Ensure that the replacement DDR4 DIMM matches the size of the DIMM it is replacing.

    You must not replace a single-rank or dual-rank DIMM with a quad-rank DIMM and vice versa. If you violate this rule, the performance of the server might be adversely affected. For DIMM socket population rules, see DIMM Population Rules.

  3. 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.
  4. Repeat Step 3 until all replacement DDR4 DIMMs are installed.
  5. Return the server to operation.
    1. Install the server top cover.

      See Install the Server Top Cover.

    2. Close the fan door.
    3. Return the server to the normal rack position.

      See Return the Server to the Normal Rack Position.

    4. Reconnect the power cords to the server power supplies and reconnect the data cables.

      See Reconnect Data Cables and Power Cords.

    5. Power on the server.

      See Power On the Server.

      Verify that the Power/OK status indicator is steady on.

  6. (Optional) Use Oracle ILOM to clear server 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.
