Chapter 9. Replacing FRUs

Important
Before you replace any FRU, read Chapter 2 "Safety information" on page 3. These precautions and
guidelines will help you work safely.
FRU replacements are to be done by trained service technicians only.
This chapter provides instructions about removing or replacing major FRUs. Not all FRUs are documented.

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed
from the computer and you are ready to install the new part. Static electricity, although harmless to you, can
seriously damage computer components and parts.
When you handle computer parts and components, take these precautions to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always carefully handle the parts and other computer components. Handle PCI cards, memory modules,
system boards, and microprocessors by the edges. Never touch 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 computer 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 computer 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 computer cover or other metal surface.
