Removing and replacing an NVDIMM
CAUTION: Do not remove an NVDIMM when any LEDs on any NVDIMM in the system are illuminated. Removing an
NVDIMM when an LED is illuminated might cause a loss of data.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before
beginning this procedure.
CAUTION: Failure to properly handle s can cause damage to components and the system board connector.
To identify NVDIMMs installed in the graphics expansion module, see "NVDIMM identification"
Prerequisites
Before replacing memory, read the memory configuration and population guidelines in the server user guide.
Procedure
1. Sanitize/erase any NVDIMMs being removed or relocated as necessary. For more information, see "NVDIMM relocation
guidelines."
2. Power down the graphics expansion module.
3. Remove the graphics expansion module.
4. Place the graphics expansion module on a flat, level work surface.
5. Remove the access panel.
6. If applicable, remove the graphics expansion from the compute module.
7. Remove all DIMM baffles.
IMPORTANT: Flip the DIMM baffle on top of the heatsink. Leave the Smart Storage Battery installed and on the
baffle when accessing the right DIMM baffle.
See "DIMM slot locations" to identify DIMMs installed in the graphics expansion module.
8. Observe the NVDIMM LEDs. Do not remove an NVDIMM when any NVDIMM LED in the system is illuminated.
9. Remove the NVDIMM-N.
