Installing an NVDIMM

CAUTION:

To avoid damage to the hard drives, memory, and other system components, the air baffle, drive blanks, and access panel must be installed when the server is powered up.

CAUTION:

To avoid damage to the hard drives, memory, and other system components, be sure to install the correct DIMM baffles for your server model.

CAUTION:

DIMMs are keyed for proper alignment. Align notches in the DIMM with the corresponding notches in the DIMM slot before inserting the DIMM. Do not force the DIMM into the slot. When installed properly, not all DIMMs will face in the same direction.

CAUTION:

Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning this procedure.

CAUTION:

Failure to properly handle DIMMs can cause damage to DIMM components and the system board connector.

CAUTION:

Unlike traditional storage devices, NVDIMMs are fully integrated in with the ProLiant server. Data loss can occur when system components, such as the processor or HPE Smart Storage Battery, fails. HPE Smart Storage battery is a critical component required to perform the backup functionality of NVDIMMs. It is important to act when HPE Smart Storage Battery related failures occur. Always follow best practices for ensuring data protection.

Prerequisites

Before installing an NVDIMM, be sure the server meets the Server requirements for NVDIMM support.

Procedure
  1. Power down the server.
  2. Remove all power:
    1. Disconnect each power cord from the power source.
    2. Disconnect each power cord from the server.
  3. Do one of the following:
  4. Remove the access panel (Removing the access panel).
    CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

  5. Locate any NVDIMMs already installed in the server.
  6. Verify that all LEDs on any installed NVDIMMs are off.
  7. Install the NVDIMM.

  8. Install and connect the HPE Smart Storage Battery, if it is not already installed (Installing an energy pack).
    NOTE:

    NVDIMMs are only supported with the HPE Smart Storage Battery. Installation of an NVDIMM requires the installation of two HPE Smart Storage batteries.

  9. Install any components removed to access the DIMM slots and the HPE Smart Storage Battery.
  10. Install the access panel.
  11. Slide or install the server into the rack.
  12. If removed, reconnect all power cables.
  13. Power up the server.
  14. If required, sanitize the NVDIMM-Ns. For more information, see NVDIMM sanitization.
