Upgrades

Serviceability Features

The computer includes features that make it easy to upgrade and service. No tools are needed for most 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, hot surfaces, or fire:

Disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.

Do not plug telecommunications or telephone connectors into the network interface controller (NIC) receptacles.

Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.

To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper workstation, setup, posture, and health and work habits for computer users, and provides important electrical and mechanical safety information. This guide is located on the Web at

WARNING! Energized and moving parts inside.

Disconnect power to the equipment before removing the enclosure.

Replace and secure the enclosure before re-energizing the equipment.

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 information.

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 damage to internal components.

Serviceability Features 17

Removing the Computer Access Panel

To access internal components, you must remove the access panel:

1. Remove/disengage any security devices that prohibit opening the computer.

2. Remove all removable media, such as compact discs or USB flash drives, from the computer.

3. Turn off the computer properly through the operating system, then turn off any external devices.

4. Disconnect the power cord from the power outlet and disconnect any external devices.

CAUTION: Regardless of the power-on state, voltage is always present on the system board

as long as the system is plugged into an active AC outlet. You must disconnect the power cord to avoid damage to the internal components of the computer.

5. Lift up on the access panel handle (1) then lift the access panel off the computer (2).

Figure 2-1 Removing the Computer Access Panel

Removing Bezel Blanks

On some models, there are bezel blanks covering the 5.25-inch drive bays that need to be removed before installing a drive. To remove a bezel blank:

1. Remove the access panel and front bezel.

2. Gently pull the subpanel, with the bezel blanks secured in it, away from the front bezel, then

remove the desired bezel blank.

CAUTION: Hold the subpanel straight when you pull it away from the front bezel. Pulling the

subpanel away at an angle could damage the pins that align it within the front bezel.

Figure 2-4 Removing Bezel Blanks from the Subpanel (Desktop Shown)

NOTE: When replacing the subpanel, ensure that the aligning pins and any remaining bezel blanks

are in their proper orientation. The logo on the subpanel should be located at the bottom of the subpanel when properly oriented.

Removing Bezel Blanks 21

Replacing the Front Bezel
