Chapter 4 Installing Optional

Components

4.1 Installation Precautions

Before you install any system component, we recommend that you read the

following sections. These sections contain important ESD precautions, pre- and

post-installation instructions.

4.1.1 ESD Precautions

Electrostatic discharge (ESD) can damage your processor, disk drives, expansion

boards, and other components. Always observe the following precautions before

you install a system component:

1. Do not remove a component from its protective packaging until you are

ready to install it.

2. Wear a wrist grounding strap and attach it to a metal part of the system unit

before handling components. If a wrist strap is not available, maintain

contact with the system unit throughout any procedure requiring ESD

protection.

AcerPower 6000 User’s Guide4-2

4.1.2 Preinstallation Instructions

Always observe the following before you install a system component:

1. Turn off the system power and all the peripherals connected to the unit before

opening it. To turn off the system:

i. Press the power button located on the front of the system unit for at least

four seconds. Quickly pressing the button puts the system in Suspend

mode only.

ii. Turn off the system main power switch located on the rear panel. If the

system main power switch is not available, unplug the system.

2. Open the system according to the instructions in section 4.2.1.

3. Follow the ESD precautions in section 4.1.1 before handling a system

component.

4. Remove any expansion boards or peripherals that block access to the DIMM

sockets or CPU socket.

5. See the following sections for specific instructions on the component you wish

to install.

Not turning off the system properly before

you start installing components may damage

your system.

Do not attempt the procedures described in

the following sections unless you are a

qualified service technician.

Chapter 4 - Installing Optional Components 4-3

4.1.3 Post-installation Instructions

Observe the following after installing a system component:

1. See to it that the components are installed according to the step-by-step

instructions in their respective sections.

2. Make sure you have set all the required jumpers. See section 2.3.2 for the

correct jumper settings.

3. Replace any expansion boards or peripherals that you removed earlier.

4. Replace the system cover.

5. Connect the necessary cables and turn on the system.

4.2 Removing and Replacing the Housing

Cover

Before you proceed, make sure that you have

turned off the system and all peripherals

connected to it. Read section 4.1.2 for

preinstallation instructions.

This section tells you how to open the housing cover when you need to install

additional components inside the system unit.

4.2.1 Removing the Housing Cover

1. Turn off power to the system unit and unplug all cables.

2. Place the system unit on a flat, steady surface.

AcerPower 6000 User’s Guide4-4

3. Remove the four screws from the rear panel. Set the screws aside. You will

need them when replacing the housing cover.

Figure 4-1 Removing the Screws

4. Push the housing cover slightly backward as indicated in Figure 4-2.

5. Pull the housing cover upward and remove it from the chassis.

Chapter 4 - Installing Optional Components 4-5

4.2.2 Replacing the Housing Cover

1. Replace the housing cover as shown in Figure 4-3.

Figure 4-3 Replacing the Housing Cover

2. Secure the housing cover with the necessary screws.

4.3 Installing and Removing Expansion

Boards

4.3.1 Installing a PCI Card

To install a PCI card:

1. Locate the PCI slot(s) on the system board.

2. Remove the bracket on the housing opposite to the empty PCI slot.

3. Insert a PCI card into the slot. Make sure that the card is properly seated.

4. Secure the card to the housing with a screw.

When you turn on the system, BIOS automatically detects and assigns resources

to the PCI devices.

Chapter 4 - Installing Optional Components 4-7

4.3.2 Installing ISA Cards

Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA

cards, make sure that the IRQs required by these cards are not previously

assigned to PCI devices to avoid resource conflicts.

Follow these steps when installing ISA cards:

1. Remove all PnP cards installed in the system, if any.

2. Install non-PnP ISA cards.

3. Turn on the system.

4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the

cards. This ensures that BIOS will not use the resources assigned to the non-

PnP ISA cards.

BIOS detects and configures only PnP cards.

6. Turn off the system.

7. Locate the expansion slots and install the PnP ISA and PCI cards.

8. Turn on the system. This time PnP BIOS automatically configures the PnP

ISA and PCI cards with the available resources.

4.4 Installing Additional Memory

The system memory is upgradable to a maximum of 256 MB via two 168-pin

DIMM sockets on board. These DIMM sockets accept DRAMs with 8-, 16-, 32-,

64-, and 128-MB capacities, 60 ns (nanoseconds) or less access time, and with

ECC. See Figure 2-1 for the location of the DIMM sockets. Section 4.4.1 tells how

to install DIMMs.

Table 4-1 lists possible memory configurations.

4.4.1 Installing a DIMM

1. Open the clips on the socket.

2. Align the DIMM with the socket.

3. Press the DIMM into the socket until the clips lock into the DIMM.

Figure 4-7 Installing a DIMM

The DIMM socket is slotted to ensure proper

installation. If you insert a DIMM but it does not fit

easily into the socket, you may have inserted it

incorrectly. Turn the DIMM around and try to insert

it again.
