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 server, see NVDIMM identification.

Prerequisites

Before replacing memory, read the memory configuration and population guidelines in the server user guide.

Procedure

Observe NVDIMM relocation guidelines.
Power down the server (Power down the server).
Remove all power:
1. Disconnect each power cord from the power source.
2. Disconnect each power cord from the server.
Do one of the following:

Remove the access panel (Remove the access panel).
Do one of the following:
- Remove the air baffle (Removing the air baffle).
- Remove the 4 LFF midplane cage (Removing and replacing a 4 LFF midplane cage).
Observe the NVDIMM LEDs. Do not remove an NVDIMM when any NVDIMM LED in the system is illuminated.
Remove the NVDIMM-N.

To replace the component, reverse the removal procedure.
