Hardware Setup 2-1

Chapter 2. Hardware Setup

2.1. CPU Socket

This server board provides dual 604-pin Zero Insertion Force (ZIF) sockets to install
the Intel Xeon CPU. You may install either one or two CPUs, but to set up system
with only one CPU, it MUST be installed in the primary socket (socket “CPU1” in
this model). To install a second processor, you must verify that the second processor
is identical to the first processor with same voltage and speed. Using non-identical
processors could cause system failure.

2-2 Chapter 2

2.2. System Memory

This server board provides four 240-pin Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) slots for Registered ECC DIMM modules with memory
expansion size up to 16GB.

ATTENTION: Populate the DDR DIMMs in-order and in-pair (of the same type
and size) by starting from DIMM1+DIMM2 to DIMM3+DIMM4.

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

These two provides the connection to EPS12V power supply.

2-4 Chapter 2

2.3.2. FAN Connectors

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.

• FAN1/FAN4: CPU and System Fan Power Connectors for CPU1

• FAN2/FAN5: CPU and System Fan Power Connectors for CPU2

• FAN3: Auxiliary Fan Power Connector

WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on
these connectors.

Hardware Setup 2-5

2.3.3. 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.

2.3.4. Front Panel Switches & Indicators Connection Headers

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.
