Follow instructions in this section to install a memory module. 
About this task
See “Memory module installation rules and order” in Setup Guide for detailed information about memory

“ATTENTION:  
Static Sensitive Device  
Ground package before opening” 
on page 140
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 140: 
•  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.
•  Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid 
metals may damage the 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.
•  Go over 
“Installation Guidelines” on page 137 to ensure that you work safely.
•  Turn off the server and peripheral devices and disconnect the power cords and all external cables (see 
“Power off the server” on page 12).
•  If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, 
or remove the server from the rack.
Important: 
•  If you are installing memory modules on the processor and memory expansion tray, do not remove the 
expansion tray. Install the modules while the expansion tray is installed in the chassis to avoid accidental 
damages to components.
•  Ensure that you have observed the installation rules and sequence in “Memory module installation rules 
and order” in Setup Guide.
•  Before installing 3DS RDIMMs or PMEMs, make sure dual-rotor fan modules are installed in the system. If 
not, follow the instructions in "Install the dual-rotor fan module upgrade kit" in Setup Guide to install the 
dual-rotor fan upgrade kit.
