About this task
Attention:
• Read
“Safety inspection checklist” on page iv and “Installation guidelines” on page 41 to ensure that you
work safely.
• Turn off the server and peripheral devices, and disconnect the power cords and all external cables, see
“Power off the server” on page 9.
• If the server is in a rack, remove it from the rack. See
“Remove the server from the rails” on page 138.
• Remove any locking device that secures the server, such as a Kensington lock or a padlock.
• Place the server on its side with the cover up.
Memory modules are sensitive to static discharge and require special handling. In addition to the standard
guidelines of
“Handling static-sensitive devices” on page 43:
• Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-
discharge gloves can also be used.
• Keep each memory module separated from one another. Do not stack memory modules directly on top of
each other during storage.
• Keep the gold memory module connector contacts from touching anything.
• Handle memory modules with care: never bend, twist, or drop a memory module.
