CAUTION: Failure to properly handle DIMMs can damage the DIMM components and the system board
connector. For more information, see the DIMM handling guidelines in the troubleshooting guide for your
product on the Hewlett Packard Enterprise website:
• HPE ProLiant Gen10 (http://www.hpe.com/info/gen10-troubleshooting)
• HPE Synergy (http://www.hpe.com/info/synergy-troubleshooting)
When the NVDIMM-N DRAM contains the only copy of restored data, perform the following procedure to
recover the information:
Procedure
1. Copy the data from the NVDIMM to some other storage device (such as SSD, HDD, or another
NVDIMM) as soon as possible (before cold reset or power loss).
2. Power down the server.
3. Extend or remove the server.
4. Remove the access panel.
5. Remove all components necessary to access the server DIMM slots and the HPE Smart Storage Battery.
For more information, see the server maintenance and service guide on the Hewlett Packard Enterprise
website (http://www.hpe.com/info/enterprise-docs).
6. Observe the NVDIMM LEDs. Do not remove an NVDIMM when any NVDIMM LED in the system is
illuminated.
7. Remove the NVDIMM-N.
8. Install a replacement NVDIMM-N.
9. Install any components removed to access the DIMM slots and the HPE Smart Storage Battery.
10. Install the access panel.
11. Install the server in the rack.
12. Power up the server.
13. Sanitize the replacement NVDIMM.
14. Copy the data from the storage device to the NVDIMM-N.
Configuring the server for NVDIMMs
After installing NVDIMMs, configure the server for NVDIMMs. For information on configuring settings for
NVDIMMs, see the HPE 16GB NVDIMM User Guide on the Hewlett Packard Enterprise website (http://
www.hpe.com/info/nvdimm-docs).
The server can be configured for NVDIMMs using either of the following:
• UEFI System Utilities—Use System Utilities through the Remote Console to configure the server for
NVDIMM memory options by pressing the F9 key during POST. For more information about UEFI System
Utilities, see the Hewlett Packard Enterprise website (http://www.hpe.com/info/uefi/docs).
• iLO RESTful API for HPE iLO 5—For more information about configuring the system for NVDIMMs, see
https://hewlettpackard.github.io/ilo-rest-api-docs/ilo5/.
