Environmental Safety Instruction
zAvoid the dusty, humidity and temperature extremes. Do not place the product in any
area where it may become wet.
z0 to 40 centigrade is the suitable temperature. (The figure comes from the request of
the main chipset)
zGenerally speaking, dramatic changes in temperature may lead to contact malfunction
and crackles due to constant thermal expansion and contraction from the welding
spots’ that connect components and PCB. Computer should go through an adaptive
phase before it boots when it is moved from a cold environment to a warmer one to
avoid condensation phenomenon. These water drops attached on PCB or the surface
of the components can bring about phenomena as minor as computer instability
resulted from corrosion and oxidation from components and PCB or as major as short
circuit that can burn the components. Suggest starting the computer until the
temperature goes up.
zThe increasing temperature of the capacitor may decrease the life of computer. Using
the close case may decrease the life of other device because the higher temperature in
the inner of the case.
zAttention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.
Environmental Protection Announcement
Do not dispose this electronic device into the trash while discarding. To minimize pollution

1-1-1 Special Features of motherboard
CPU Smart Fan (The Noise Management System)
It’s never been a good idea to gain the performance of your system by sacrificing its
acoustics. CPU Smart Fan Noise Management System is the answer to control the
noise level needed for now-a-day’s high performance computing system. The system
will automatically increase the fan speed when CPU operating loading is high, after
the CPU is in normal operating condition, the system will low down the fan speed for
the silent operating environment. The system can provide the much longer life cycle
for both CPU and the system fans for game use and business requirements.
OC-CON solid capacitors (High-polymer Solid Electrolysis Aluminum Capacitors)
The motherboard adopts OC-CON solid capacitors to make it possible for
motherboard to work from 55 degrees Centigrade below zero to 125 degrees
centigrade. OC-CON capacitors possess superior physical characteristics to prolong

Hardware Installation
WARNING! Turn off your power when adding or removing expansion cards or
other system components. Failure to do so may cause severe
damage to both your motherboard and expansion cards.
2-1 CPU Installation
This motherboard provides an 1155-pin DIP, LGA 1155 Land Grid Array socket,
referred to as the LGA 1155 socket.
The CPU that comes with the motherboard should have a cooling FAN attached to
prevent overheating. If this is not the case, then purchase a correct cooling FAN
before you turn on your system.
NOTED! Be sure that there is sufficient air circulation across the processor’s
heat sink and CPU cooling FAN is working correctly, otherwise it
may cause the processor and motherboard overheat and damage,
you may install an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the LGA
1155 socket and open it by first pulling the level sideways away from the socket then
upward to a 135-degree angle. Insert the CPU with the correct orientation as shown
below. The notched corner should point toward the end of the level. Because the
CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation
as shown.
When you install the CPU into the LGA 1155 socket, there’s no force required CPU
insertion; then presses the level to locate position slightly without any extra force.

3-1 Motherboard Internal Connectors
(1) Power Connector (24-pin block): ATXPWR1
ATX Power Supply connector: This is a new defined 24-pins connector that
usually comes with ATX case. The ATX Power Supply allows using soft power
on momentary switch that connect from the front panel switch to 2-pins Power
On jumper pole on the motherboard. When the power switch on the back of the
ATX power supply turned on, the full power will not come into the system board
until the front panel switch is momentarily pressed. Press this switch again will
turn off the power to the system board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power
supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin
and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the
20-pin power plug can provide at least 15A on +12V and the power supply unit
has a minimum power rating of 350W. The system may become unstable or may
not boot up if the power is inadequate.
** If you are using a 20-pin power plug, please refer to Figure1 for power supply
connection. Power plug form power supply and power connectors from motherboard
both adopt key design to avoid mistake installation. You can insert the power plug into
the connector with ease only in the right direction. If the direction is wrong it is hard to
fit in and if you make the connection by force if is possible.

Thunder Protection Feature
Introduction:
Thunder is such formidable natural force that it can render massive damage to electronic
products of all kinds. In thunderstorm season computer systems without powerful thunder
protection designs are vulnerable to electric surge damage. High-priced building with
thunder protection measures may be a good choice, but usually costly and with corners
uncovered. The best solution for both cybercafés owner and common users would be
Jetway Thunder Series motherboards.
Thunder Protection Technology from Jetway Thunder Series Motherboard
Jetway Thunder series motherboards are integrated with double thunder-protection walls,
one from network port and the other from LAN chip. When it thunders, the first
thunder-protection wall will analyze and recognize thunder surge in network cable and
transfer it to ground wire area. The second thunder-protection wall will protect against any
residual electric current or runaway electrons to ensure safety of network card and other
components of the motherboard.
Laboratory test statistics on IEC61000-4-5 (1.2-50us) standardized thunder electric surge
tests have verified that Jetway Thunder series motherboard can endure up to 9KV electric
surge and protect the system from possible thunder damage.
IEC61000-4-5 (1.2-50us) Standardized Thunder Electric Surge Laboratory Test
Medium rise time: T1=1.2us±30%, T2=50us±30%
Test1: Current Partial Discharge tests on Jetway Thunder Series Motherboards with double
Thunder-protection Walls.
Test Result: Each MB can endure up to 9KV voltage of electric surge. Some motherboards
will restart (mostly depends on LAN chip), but no damage occurs to motherboards or
components of the board. System works normally after a restart.
Test2: Current Partial Discharge tests on Motherboards without Thunder-protection function
Test Result: LAN chips are damaged when testing voltage reached to 5KV. System fails to
operate normally (in most cases systems can not access to network) after a restart.

17
Conclusion: Jetway’s Thunder Series motherboard can guard motherboard from thunder
electric surge damage with effect and ensure system security from as high as 9KV volts of
electric surge.
Bonus of Thunder-protection Motherboard
Jetway Thunder series motherboards adopt dual thunder protection walls to cover every
corner in network loops. Such a complete thunder protection provided to users, especially
cybercafés means less repair cost and more effective business time. Jetway Thunder series
can guard system stability with effect. With Jetway Thunder series motherboards, together
with reasonable disposal of electric wires, proper placing of electric devices, piped network
cables and other necessary thunder protection devices, your computer system will be intact
in thunderstorm weather.
Notice! Thunder protection function an optional feature is only supported by
Thunder Series motherboard.
