Remove a memory module
Use this information to remove a memory module.
About this task
Attention:
• Read "Installation Guidelines" on page 121 and "Safety inspection checklist" on page 122 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 14.
• If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover,
or remove the server from the rack. See "Remove the server from rack" on page 124.
• 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 123.
– 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.
• After you install or remove a memory module, you must change and save the new configuration
information by using the Setup utility. When you turn on the server, a message indicates that the memory
configuration has changed. Start the Setup utility and select Save Settings to save changes. (see the
ThinkSystem SR670 V2 Setup Guide for more information.)
Important: Remove or install memory modules for one processor at a time.
