Handling Static-Sensitive Devices; Removing The Server Cover - Lenovo ThinkServer RD230 Hardware Maintenance Manual

Handling static-sensitive devices

Attention
Do not open the static-protective package containing the new part until the defective part has been removed from the
server and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage
server components and parts.
When you handle server parts and components, take these precautions to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Wear an electrostatic-discharge wrist strap, if one is available.
• Always carefully handle the parts and other components (such as PCI cards, memory modules, system
boards, and microprocessors) by its edges or its frame. Do not touch solder joints, pins, or exposed
circuitry.
• Prevent others from touching the parts and other computer components.
• Before you replace a new part, touch the static-protective package containing the new part to a metal
expansion-slot cover or other unpainted metal surface on the server for at least two seconds. This
reduces static electricity from the package and your body.
• Remove the new part from the static-protective package and directly install it in the server without
placing it on any other surface. If it is hard for you to do this in your specific situation, place the
static-protective package of the new part on a smooth, level surface, and then place the new part on
the static-protective package.
• Do not place the part on the server cover or other metal surface.
• Take additional care when handling devices during cold weather. Heating reduces indoor humidity
and increases static electricity.
