Install a memory module

Use this information to install a memory module.
About this task
Attention:
• Read "Installation guidelines" on page 83 to ensure that you work safely.
• Power off the server and disconnect all power cords for this task.
• Memory modules are sensitive to static discharge and require special handling. Refer to the standard
guidelines for "Handling static-sensitive devices" on page 85:
– 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.
