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 110:
• 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.
