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
• 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.
Before installing a memory module, make sure that you understand the required installation order, depending
on whether you are implementing memory mirroring, memory rank sparing, or independent Memory Mode.
See ThinkSystem SR850 Memory Population Reference for the required installation order.
If you are installing an optional processor, install it before installing memory modules. See
