Remove a memory module
Use this information to remove a memory module.
About this task
Attention:
• Read “Installation Guidelines” on page 185 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 188.
– 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 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.
