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 DIMMs can cause damage to DIMM components and the system board
connector.
To identify NVDIMMs installed in the compute 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 compute module .
3. Remove the compute module .
4. Place the compute module on a flat, level work surface.
5. Remove the access panel .
6. 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 compute module.
7. Observe the NVDIMM LEDs. Do not remove an NVDIMM when any NVDIMM LED in the system is
illuminated.
8. Remove the NVDIMM-N.
