Attention:
• Disconnect all power cords for this task.
• memory modules are sensitive to static discharge and require special handling. In addition to the standard
guidelines for Handling static-sensitive devices:
– 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 do not touch each other. 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.
– Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid
metals may damage the memory modules.
– Do not insert memory modules while holding packages or passive components, which can cause
package cracks or detachment of passive components by the high insertion force.
Before installing a memory module:
1. Touch the static-protective package that contains the new memory module to any unpainted surface on
the outside of the server. Then, take the new memory module out of the package and place it on a
static-protective surface.
2. Locate the required memory module slot on the system board.
Note: Ensure that you observe the installation rules and sequence in "Memory module installation
rules" on page 140.
3. If you are going to install a DCPMM for the first time, refer to "DC Persistent Memory Module (DCPMM)
setup" on page 138.
Note: A DCPMM module looks slightly different from a DRAM DIMM in the illustration, but the
installation method is the same.
