Install a memory module
Use this information to install a memory module.
Ground package before opening”
Attention:
• 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 56:
– 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.
