a) Locate the DIMM that you are removing, and then open the ejector levers at each end of its DIMM slot.
Step 4
Install a new DIMM:
Before installing DIMMs, see the memory population rules for this server:
DIMM Population Rules and Memory
Performance Guidelines, on page 82
.
Note
You must use DIMM blanking panels in any DIMM slots that do not have DIMMs installed to ensure adequate
air flow.
Note
a) Align the new DIMM with the empty slot on the CPU module board. Use the alignment feature in the DIMM slot to
correctly orient the DIMM.
b) Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock
into place.
Step 5
Return the CPU module to the chassis:
a) With the two ejector levers open, align the CPU module with an empty bay.
b) Push the module into the bay until it engages with the midplane connectors and is flush with the chassis front.
c) Rotate both ejector levers toward the center until they lay flat and their latches lock into the front of the module.
Step 6
Reconnect power cords to all power supplies and then allow the server to boot to standby power mode (indicated when
the front panel Power button LED lights amber).
Step 7
Fully power on the server by pressing the Power button.
Verify that the power LED on the front of the CPU module returns to solid green.

Replacing Intel Optane DC Persistent Memory Modules
This topic contains information for replacing Intel Optane Data Center Persistent Memory modules (DCPMMs),
including population rules and methods for verifying functionality. DCPMMs have the same form-factor as
DDR4 DIMMs and they install to DIMM slots.
DCPMMs and their sockets are fragile and must be handled with care to avoid damage during installation.
Caution
To ensure the best server performance, it is important that you are familiar with memory performance guidelines
and population rules before you install or replace DCPMMs.
Note
Intel Optane DC persistent memory modules require Second Generation Intel Xeon Scalable processors. You
must upgrade the server firmware and BIOS to version 4.0(4) or later and install the supported Second
Generation Intel Xeon Scalable processors before installing DCPMMs.
Note
DCPMMs can be configured to operate in one of three modes:
