CAUTION:
• To prevent improper cooling and thermal damage, always install DIMMs of the same height in the
compute module.
• This compute module does not support mixing standard and nonstandard height DIMMs.
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 DIMM s 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.
