Replace A Memory Dimm; Replace An M.2 Adapter - Lenovo ThinkAgile VX1320 Hardware Replacement Manual

Replace a memory DIMM

A node might be able to self-correct for certain memory errors, however, failed memory can lead to system
degradation and should be quickly replaced. Indications of a failed DIMM are:
• A post error on boot
• An error in XCC
• Not all memory is detected. For example, the model should have 256 GB per node and the host only
shows 240 GB
The CRUs for memory DIMMs are as follows:
Description
ThinkSystem 8GB
TruDDR4 2666MHz (1Rx8,
1.2V) ECC UDIMM
ThinkSystem 16GB
TruDDR4 2666MHz (2Rx8,
1.2V) ECC UDIMM
To replace a memory DIMM:
1. Identify the failed DIMM by either checking the event logs in UEFI setup or use the XCC web console to
browse the post event log. The event log contains information about the location of the DIMM fault.

the
VMware Storage and Availability Technical Documents Repository
3. Power off the node and if the cable management arm is not in place, disconnect all the cables. Pull the
