• Read the following section(s) to ensure that you work safely.
– “Safety” on page iii
– “Installation Guidelines” on page 51
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 11 .
• 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 for “Handling static-sensitive devices” on page 53 :
– 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.
– 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.
