About this task
Attention:
• Read
“Installation Guidelines” on page 57 and “Safety inspection checklist” on page 58 to ensure that you
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 75.
• Make sure to remove or install memory module 20 seconds after disconnecting power cords from the
system. It allows the system to be completely discharged of electricity and safe for handling memory
module.
• Keep static-sensitive parts in their static-protective packages until installation to prevent exposure to
static electricity. Handle the parts with an electrostatic-discharge wrist strap or other grounding systems.
Place the parts on a static-protective surface.
• If you are not installing a replacement memory module to the same slot, make sure you have memory
module filler available.
• Memory modules are sensitive to static discharge and require special handling. Refer to the standard
guidelines for
“Handling static-sensitive devices” on page 60.
– 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.
– 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.
Important: Remove or install memory modules for one processor at a time.
