Warning !
1. Battery
Batteries on board are consumables.
The life time of them are not guaranteed.
2. Fless solution with HDD
The specication & limitation of HDD should be considered carefully when
the fanless solution is implemented.
3. We will not give further notication in case of changes of
product information and manual.
4. SATA interface does not support Hot SWAP function.
5. There might be a 20% inaccuracy of WDT at room temperature.
6. Please make sure the voltage specication meets the requirement
of equipment before plugging in.
8. Caution! Please notice that the heat dissipation problem could cause the MB
system unstable. Please deal with heat dissipation properly when
buying single MB set.
9. Please avoid approaching the heat sink area to prevent users from
being scalded with fanless products.
12. It is important to install a system fan toward the CPU to decrease
the possibility of overheating / system hanging up issues,
or customer is suggested to have a ne cooling system to dissipate heat
from CPU.
11. DO NOT apply any other material which may reduce cooling
performance onto the thermal pad.
10. If users repair, modify or destroy any component of product unauthorizedly,
We will not take responsibility or provide warranty anymore.
7. There are two types of SSD, commercial grade and industrial grade, which
provide different read/write speed performance, operation temperature and
life cycle. Please contact sales for further information before making orders.

Hardware Notice Guide
1. Before linking power supply with the motherboard, please attach DC-in adapter to
the motherboard rst. Then plug the adapter power to AC outlet.
Always shut down the computer normally before you move the system unit or
remove the power supply from the motherboard. Please unplug the DC-in adapter rst
and then unplug the adapter from the AC outlet.
Please refer photo 1 as standard procedures.
2. In case of using DIRECT DC-in (without adapter), please check the allowed range
for voltage & current of cables. And make sure you have the safety protection for
outer issues such as short/broken circuit, overvoltage, surge, lightning strike.
3. In case of using DC-out to an external device, please make sure its voltage and
current comply with the motherboard specication.
4. The total power consumption is determined by various conditions
(CPU/motherboard type, device, application, etc.). Be cautious to the power cable
you use for the system, one with UL standard will be highly recommended.
5. It’s highly possible to burn out the CPU if you change/ modify any parts of
the CPU cooler.
6. Please wear wrist strap and attach it to a metal part of the system unit
before handling a component. You can also touch an object which is
ground connected or attached with metal surface if you don't have wrist strap.
7. Please be careful to handle & don't touch the sharp-pointed components on
the bottom of PCBA.
8. Remove or change any components form the motherboard will VOID the warranty of
the motherboard.
9. Before you install/remove any components or even make any jumper setting
on the motherboard, please make sure to disconnect the power supply rst.
(follow the aforementioned instruction guide)
10. "POWERON after PWR-Fair” function must be used carefully as below:
When the DC power adaptor runs out of power, unplug it from the DC current;
Once power returns, plug it back after 5 seconds.
If there is a power outage, unplug it from the AC current, once power returns,
plug it back after 30 seconds. Otherwise it will cause system locked or made
a severe damage.
Remark 1:
Always insert/unplug the DC-in horizontally & directly to/from the motherboard.
DO NOT twist, it is designed to t snugly.
Moreover, erratic pull / push action might cause an unpredictable damage to the
component & system unit.

Chapter-2
This chapter provides the information how to install the hardware of 2I385PW.
Please follow section 1-4, 2-1 and 2-2 to check the delivery package and unpack
carefully. Please follow the jumper setting procedure.
You should follow these
steps to protect the board from the static electric
discharge whenever you handle the board:
1. Ground yourself by a grounded wrist strap at all times when you handle the 2I385PW.
Well secure theALLIGATOR clip of the strap to the end of the shielded wire lead from
a grounded object. Please put on and connect the strap before handling the
2I385PW for harmlessly discharge any static electricity through the strap.
2. Please use anti-static pad to put any components, parts, or tools on the pad whenever
you work on them outside the computer. You may also use the anti-static bag instead of
the pad. Please ask your local supplier for necessary parts on anti-static requirement.
3. Do not plug any connector or set any jumper when the power is on.
Hardware Installation
2-1 Unpacking Precaution
