Chapter 2. Hardware Setup
2.1. CPU Socket
This motherboard provides a ZIF (Zero Insertion Force) Socket 940 to install AMD
Socket 940 CPU. The CPU you bought should contain with a kit of heatsink, cooling
fan, retention frame and back plate. If that’s not the case, buy one specially designed
for Socket 940.
NOTE: This server board supports installing either one or two CPUs. To set up
system with only one CPU, you MUST install it in Socket CPU1.

2.2. System Memory
• 64-bit Mode: Start populating DIMMs only at slot DIMM2, DIMM4,
DIMM6, and/or DIMM8.
• 128-bit Mode: Start populating in pairs and in order from DIMM1+DIMM2.
• At least one DIMM slot must be populated for the system to POST.
• For best performance, populate DIMMs symmetrically.
• To access DIMMs on CPU2, both processors must be installed.

Hardware Setup 2-3
2.2.1. 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.

2.3. 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 system board and/or peripherals. Plug in the AC power cord only after
you have carefully checked everything.
2.3.1. EPS Power Connectors (EPS12V_1, EPS12V_2)
These two provides the connection to EPS12V power supply.

Hardware Setup 2-5
2.3.2. FAN Connectors (CPUFAN1~2, SYSFAN1, AUXFAN1~4)
These 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.
• CPUFAN1: Power connector for CPU1 cooling fan
• CPUFAN2: Power connector for CPU2 cooling fan
• SYSFAN1: System Fan Power Connector
• AUXFAN1~AUXFAN4: Auxiliary Fan Power Connectors
WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on
these connectors.

2.3.3. CMOS Memory Clearing Header (CCMOS1)
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.

2.3.4. Front Panel Switches & Indicators Connection Headers
(FPIO1)
This header is used for connecting switches and LED indicators on the chassis front
panel.
Watch the power LED pin position and orientation. The mark “+” align to the pin in
the figure below stands for positive polarity for the LED connection. Please pay
attention to connect these headers. A wrong orientation will only cause the LED not
lighting, but a wrong connection of the switches could cause system malfunction.
• HLED (Pin 1, 3): Connects to the HDD LED cable.
• RST (Pin 5, 7): Connects to the Reset Switch cable.
• SPKR (Pin 13, 15, 17, 19): Connects to the System Speaker cable.
• SLED (Pin 2, 4): Connects to the Suspend LED cable.
• PWR (Pin 6, 8): Connects to the Power Switch cable.
• C.O. (Pin 14, 16): Connects to Case Open (Intrusion) device.
• FLED (Pin 18, 20): Connects to the Fault LED cable.
