Install a memory module
Memory modules are installed in the compute system boards that are accessed from the front of the server.

on page 58
See “Memory module installation rules and order” on page 58 for detailed information about memory
configuration and setup.
Attention:
Memory modules are sensitive to static discharge and require special handling. In addition to the
standard guidelines for “Handling static-sensitive devices” on page 58 :
• Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-
discharge gloves can also be used.
• Never hold two or more memory modules together so that they touch. Do not stack memory modules
directly on top of each other during storage.
• Never touch the gold memory module connector contacts or allow these contacts to touch the outside of
the memory-module connector housing.
• Handle memory modules with care: never bend, twist, or drop a memory module.
Before installing a memory module, make sure that you understand the required installation order, depending
on whether you are implementing memory mirroring, memory rank sparing, or independent memory mode.
See
ThinkSystem SR860 Memory Population Reference
for the required installation order.
If you are installing an optional processor, install it before installing memory modules. See “Install a
processor-heat-sink module” on page 101
Before installing a memory module:
1. If you are installing DC Persistent Memory Module (DCPMM) for the first time, follow the instructions in
“DC Persistent Memory Module (DCPMM) setup” on page 78 .
2. Read the safety information and installation guidelines (see “Safety” on page iii and “Installation
Guidelines” on page 56 ).
3. Touch the static-protective package that contains the component to any unpainted metal surface on the
server; then, remove it from the package and place it on a static-protective surface.

Step 1. Open the memory module connector retaining clips. If a memory module is already installed in the
connector, remove it.
Step 2. Align the keys on the memory module that you are installing with the connector; then, insert the
memory module.
Step 3. Firmly press both ends of the memory module straight down into the connector until the retaining
clips snap into the locked position.
