Remove a memory module
Use this information to remove a memory module.
About this task
Attention: 
•  Read 
“Installation Guidelines” on page 55 and “Safety inspection checklist” on page 56 to ensure that you 
work safely.
•  Memory modules are sensitive to static discharge and require special handling. Refer 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 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.
•  In the case of processor board replacement, keep records of the slots in which the modules are installed, 
and make sure to install them back to the exact same slots after processor board replacement.
