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.
