• 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 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.
• Go over
“Installation Guidelines” on page 41
to ensure that you work with safety.
• Turn off the server and peripheral devices and disconnect the power cords and all external cables (see
“Power off the server” on page 13
).
• 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.
