Attention:
• Read “Safety inspection checklist” on page iv and “Installation guidelines” on page 41 to ensure that you
work safely.
• Touch the static-protective package that contains the component to any unpainted metal surface on the
server; then, remove it from the package and place it on a static-protective surface.
Memory modules are sensitive to static discharge and require special handling. In addition to the standard
guidelines of
“Handling static-sensitive devices” on page 43 :
• Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-
discharge gloves can also be used.
• Keep each memory module separated from one another. Do not stack memory modules directly on top of
each other during storage.
• Keep the gold memory module connector contacts from touching anything.
• Handle memory modules with care: never bend, twist, or drop a memory module.
