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 2000 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. Read section 1.5 for information on how to properly turn off the
system.
Make sure that the system is unplugged.
2. Open the system according to the instructions in the housing installation
manual.
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.
Do not attempt the procedures described in
the following sections unless you are a
qualified service technician.

4.3 Disassembling and Reassembling the
System
When upgrading, you may need to disassemble your system in order to access
the system board and other components inside the system.
To disassemble the system:
1. The metal cover inside the housing gives additional support to the housing’s
structure. To remove the metal cover, remove the two screws that attach the
metal bracket to the riser card. Insert two fingers into the hole and gently
draw it back as you lift it up.

3. When the drives have been removed, you can now access the system board
and the riser card.
To reassemble the system:
To reassemble the system, simply reverse the procedure. However, before you
reassemble your system, make sure that you have installed all necessary
components and connected the cables.

Boards
4.5.1 Installing a PCI Card
To install a PCI card:
1. Turn off and unplug the system.
2. Locate the riser card.
3. Locate an empty PCI slot on the slot board.
4. Remove the bracket on the housing opposite to the empty PCI slot.
5. Insert a PCI card into the slot. Make sure that the card is properly seated.

4.6 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 PC-66 compliant DIMMs
with 16-, 32-, 64-, and 128-MB capacities. See Figure 2-1 for the location of the
DIMM sockets. Section 4.6.1 tells how to install DIMMs.
Table 4-1 lists possible memory configurations.

4.6.1 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 4-13 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.

Chapter 4 - Installing Optional Components 4-15
4.6.2 Removing a DIMM
1. Press the holding clips on both sides of the socket outward to release the
DIMM.
2. Gently pull the DIMM out of the socket.

4.6.3 Reconfiguring the System
The system automatically detects the amount of memory installed. Run Setup to
view the new value for total system memory and make a note of it.
4.7 Upgrading the CPU
The board supports a Pentium II processor or a Celeron processor. Both
processors come in a new enclosed packaging technology called S.E.C.
(Single-Edge Contact) cartridge. The only difference between the two is that the

AcerPower 2000 User’s Guide4-16
Pentium II processor comes with a 256-KB or 512-KB built-in second-level cache,
while the Celeron processor comes only with an internal cache. Both are capable
of increasing the performance of 32-bit software and multimedia applications.
4.7.1 Removing the Pentium II CPU
Observe the ESD precautions when installing or
removing a system component. See section 4.1.1.
Before you can replace or upgrade your processor, you need to remove the
previously installed processor on the system board.
Follow these steps to remove the Pentium II CPU:
1. Disconnect the 3-pin and 2-pin heatsink fan cables from the system board.
Figure 4-15 Disconnecting the heatsink cable from the system board

Chapter 4 - Installing Optional Components 4-17
To insure proper installation, remove all DIMMs
from their sockets before installing or removing the
CPU. See section 4.6.2 for instructions on
removing a DIMM.
2. Press the latches on both sides of the processor to release it from the retention
mechanism. You will hear a click sound once the latch is released.
3. Pull out and lift up the processor to detach it from the CPU connector.
