About this task
S002
CAUTION:
The power-control button on the device and the power switch on the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one power cord. To
remove all electrical current from the device, ensure that all power cords are disconnected from the
power source.
See “Memory module installation rules and order” on page 33 for detailed information about memory
configuration and setup.
Attention:
• Read
“Installation Guidelines” on page 29 and “Safety inspection checklist” on page 30 to ensure that you
work safely.
• 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.
• Make sure to adopt one of the supported configurations listed in
“Memory module installation rules and
order” on page 33
.
• Memory modules are sensitive to static discharge and require special handling. Refer to the standard
guidelines at
“Handling static-sensitive devices” on page 31:
– 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.
