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 EEB 3.0 form factor.
1. Face the side of the I/O ports toward the control panel.
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.

2.3. Installing the CPU
This server board provides dual 604-pin
Zero Insertion Force (ZIF) sockets to
install the Intel Xeon CPU.
NOTE: This server board also supports
the Xeon CPU of 603-pin package.
NOTE: This server board supports installing either one or two CPUs. To set up
system with only one CPU, you MUST install it in the Primary Processor Socket
(Socket CPU0 in this model). To install a second processor, you must verify that the
second processor is identical to the first processor of same voltage and speed. Using
non-identical processors could cause system failure.
2.3.1. Installing Retention Modules
1. Remove power from your system by unplugging
the AC power cord.
2. Remove the chassis cover (see your system or
chassis documentation for instructions).
3. Locate the CPU sockets.
4. Insert the retention modules and tighten four
retention screws.

2.3.4. Installing Fan to Wind Tunnel Assemblies
1. Attach the cooling fan with its airflow direction pointed to heatsink to the air
intake portion of wind tunnel.
2. Attach the air intake assembly to the side of the wind tunnel nearest to the front of
the chassis.
Instead of attaching cooling fan to the side of the wind tunnel, the fan itself could
also be attached to the top of the center portion of wind tunnel.
3. Align the tabs on the assembly with the slots in the wind tunnel portion, and then
snap the lower portion of the fan holder over the tabs on the center portion.
4. Attach the air outlet portion of the wind tunnel.
5. Attach CPU Fan 1 power cable to the server board at location FAN1 and/or attach
CPU Fan 2 power cable at location FAN2.
NOTE: The system airflow should be toward the front of the chassis. If there are two
processors installed, the fans should be positioned side by side.

2.4. System Memory
This server board provides six 184-pin Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) slots for Registered ECC DIMM modules with memory expansion
size up to 12GB (DDR266/DDR200).

2.4.2. Installing and Removing Memory Modules
ATTENTION: Populate the DDR DIMMs in-order and in-pair (of the same type
and size) by starting from DIMM1+DIMM2, DIMM3+DIMM4, to DIMM5+DIMM6.
The system may hang or appear unstable if the DIMM ordering is not followed.
SI-2P+
Hardware Setup 2-7
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. EPS12V Power Connectors
These two connectors connect to EPS12V power supply. This server board requires an
EPS12V power supplier with 460W capacity at least for Pentium 4 Xeon CPU
system.
WARNING: This server board only supports EPS12V power supplies and will not
operate with other types. DO NOT use ATX 2.x, ATX12V and dual AMD power
supplies as they will damage the board and void your warranty.
NOTE: The auxiliary 12V power (J37B1) is necessary to support Intel Xeon CPUs.
Failing to provide such extra power will result in the system’s booting failure.

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.
• FAN_1: CPU0 Fan
• FAN_2: CPU1 Fan
• FAN_3/4/5: System Fan
WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on
these connectors.

2.5.3. CMOS Memory Clearing Header
This header uses a jumper cap to clear the CMOS memory.
• Pin 1-2 shorted (default): Normal operation.
• Pin 2-3 shorted: Clear CMOS memory.
ATTENTION: Turn the system power off first (including the +5V standby power)
before clearing the CMOS memory. Failing to do so may cause your system to work
abnormally or malfunction.
