7 Gaining Access to System Components
This chapter describes how to gain access to major internal components so you can upgrade and
service your system.
WARNING This is a user-serviceable system. Service and upgrade tasks should be
performed by users who can follow instructions in a manual to service
equipment, and can do so without harm to themselves or damage to the
equipment.
Before You Begin
WARNING The system is always on when connected to AC power. Before opening the
system, disconnect the system’s power cord from its AC power outlet.
WARNING Internal components may be at high temperatures. Allow time for them to cool
before handling them.
WARNING Internal components can be damaged by static electricity. Use an antistatic
wrist strap connected to the bare metal of the system’s chassis to protect
against electrostatic discharge.
NOTE “Right side” and “left side” are as seen from the front of the system.
Avoiding Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect against
electrostatic discharge, take the following precautions:
♦
Disconnect the base unit from AC power before opening the base unit.
♦
Touch the bare metal of the base unit chassis before touching any internal components.
♦
Handle all printed circuit boards as little as possible and only by the edges. Do not touch any
gold contacts on a circuit board.
♦
Leave new parts in their protective packaging until you install them.
♦
Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system.
Once you use a disposable wrist strap, you cannot use it again.
♦
Attach an antistatic wrist strap to any bare metal part of the base unit chassis. The metal
conductor in the elastic sleeve of a reusable antistatic strap must contact bare skin.
