Serviceability Features

The Microtower computer includes features that make it easy to

upgrade and service. A Torx T-15 screwdriver is needed for many of

the installation procedures described in this chapter.

Warnings and Cautions

Before performing upgrades be sure to carefully read all of the

applicable instructions, cautions, and warnings in this guide.

WARNING: To reduce the risk of personal injury from electrical shock

and/or hot surfaces, be sure to disconnect the power cord from the wall

outlet and allow the internal system components to cool before touching.

WARNING: To reduce the risk of electrical shock, fire, or damage to the

equipment, do not plug telecommunications/telephone connectors into the

network interface controller (NIC) receptacles.

CAUTION: Static electricity can damage the electrical components of the

computer or optional equipment. Before beginning these procedures,

ensure that you are discharged of static electricity by briefly touching a

grounded metal object. See Chapter 4, “Electrostatic Discharge” for more

information.

CAUTION: When the computer is plugged into an AC power source,

voltage is always applied to the system board. You must disconnect the

power cord from the power source before opening the computer to

prevent system board damage.
