Chapter 2. Hardware Setup
2.1. Precautions
Please pay attention to the following precautions before setting up any hardware.
1. Always switch off the power supply and unplug the power cord from the wall
outlet before installing the board or changing any settings.
2. Ground yourself properly by wearing a static safety wrist strap before removing
the board from the antistatic bag.
3. Hold the board by its edges. Avoid touching any component on it.
4. Avoid touching module contacts and IC chips
5. Place the board on a grounded antistatic surface or on the antistatic bag that came
with the board.

2.2. Installing the Server Board
Before installing the server board, exam your chassis to ensure this server board fits
into it. Your chassis should support micro ATX form factor.
1. Face the side of the I/O ports toward the rear part of the chassis.
2. Locate the screw holes on the server board and the chassis base.
3. Place all the studs or spacers needed on the chassis base and have them tightened.
4. Line up all the screw holes on the board with those studs or spacers on the chassis.
5. Tightens all the screw holes.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs
or spacers if they are already secured on the chassis base and are without
mounting-holes on the server board to align with.

Hardware Setup 2-3
2.3. Install Pentium® 4 CPU and Heatsink Supporting-Base
This motherboard provides a ZIF
(Zero Insertion Force) Socket 478
to install Intel
The CPU you bought should have a
kit of heatsink and cooling fan along
with. If that’s not the case, buy one
specially designed for Pentium
Socket 478.
1. Locate the 478-pin ZIF socket
on the motherboard. Fasten the
Retention Module Base onto the
motherboard.
ATTENTION: If you are using
chassis specially designed for
Pentium® 4, please pay attention to
the location of metal studs or
spacers if they are already installed
on the chassis. Be careful not let the
metal studs or spacers contact the
printed circuit wire or parts on the
PCB.

2. Pull the CPU socket lever
sideways away from the socket
and then upwards to 90 degree.
Insert the CPU with the correct
orientation. Do not use extra
force to insert CPU; it only fits
in one orientation. Close down
the socket lever while holding
down the CPU.
3. Put the heatsink faces down
onto the CPU until it completely
covers the CPU.
4. Put the Fan and Retention Mechanism Assembly onto the heatsink. Make sure all
the four Retention Locks at each side of the Fan and Retention Mechanism
Assembly snap into the Retention Holes.
User’s Manual
2-4 Chapter 2
5. Push down the Retention Lock at both sides of the Fan and Retention Mechanism
Assembly to lock up together with the Retention Module Base.
6. The Fan and Retention Mechanism Assembly and Retention Module Base should
now firmly lock up with each other with the heatsink inside.
ATTENTION: Do not forget to set the correct bus frequency and multiple for your
processor.
2.4. System Memory
This server board provides two 184-pin Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) slots for PC1600/PC2100 un-buffered low profile memory
modules with memory expansion size up to 2GB.

Hardware Setup 2-5
2.4.2. Installing and Removing Memory Modules
Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
1. Locate the DIMM slot on the board.
2. Hold two edges of the DIMM
module carefully, keep away of
touching its connectors.
3. Align the two notch keys on the
module with the two ribs on the slot.
4. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snaps into the mounting notch. Do not force the DIMM module in
with extra force as the DIMM module only fit in one orientation.
5. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
ATTENTION: As the static electricity can damage the electronic components of the
computer or optional modules, make sure you are discharged of static electricity by
touching a grounded metal object briefly before starting these procedures.

2.5. Connectors, Headers, and Switches
All the connectors, headers and switches mentioned here are depending on your
system configuration. Some features you may (or may not) have to connect or to
configure depending on the peripherals you have connected.
WARNING: Always power off the computer and unplug the AC power cord before
adding or removing any peripheral or component. Failing to so may cause severe
damage to your server board and/or peripherals. Plug in the AC power cord only after
you have carefully checked everything.
2.5.1. ATX Power Connectors
It would be recommended to supply an ATX12V power with 300W, 20A +5VDC
capacity at least for heavily loaded system, and 720mA +5VSB at least for supporting
Wake-On-LAN feature.
SI-1Ns
Hardware Setup 2-7
2.5.2. FAN Connectors
These 3-pin connectors each provide power to the cooling fans installed in your
system.
The CPU must be kept cool by using a powerful fan with heatsink. The system is
capable of monitoring the speed of the CPU fan.
• FAN1/FAN2: With speed monitoring support in BIOS menu
• FAN4/FAN5: Without speed monitoring support in BIOS menu
WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on
these connectors.
