1.7 Safety Precautions
Warning! Always completely disconnect the cord from your chassis
whenever you work with the hardware. Do not make connections while
the is on. Sensitive electronic components can be damaged by sudden
surges. Only experienced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static charge before touching the
motherboard. Modern electronic devices are very sensitive to static
electric discharges. As a safety precaution, use a grounding wrist strap
at all times. Place all electronic components on a static-dissipative
surface or in a static-shielded bag when they are not in the chassis.
Caution! The computer is provided with a battery-ed Real-time Clock
circuit. There is a danger of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type recommended by the
manufacturer. Discard used batteries according to manufacturer’s
instructions.
Caution! There is a danger of a new battery exploding if it is incorrectly installed.
Do not attempt to recharge, force open, or heat the battery. Replace the
battery only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to the manufacturer’s
instructions.

1.8 Jumper Settings
This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboard default settings and your options for
each jumper.
1.8.1 How to set jumpers
You can configure your motherboard to match the needs of your application by set-
ting the jumpers. A jumper is a metal bridge that closes an electrical circuit. It consists
of two metal pins and a small metal clip (often protected by a plastic cover) that slides
over the pins to connect them. To “close” (or turn on) a jumper, you connect the pins
with the clip. To “open” (or turn off) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-
ting jumpers.
1.8.2 CMOS clear & ME clear (JCMOS1 & JME1)
The AIMB-705 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set J1 to 2-3 closed for just a few sec-
onds, and then move the jumper back to 1-2 closed. This procedure will reset the
CMOS to its default setting.
1.8.3 Watchdog timer output (JWDT1)
The AIMB-705 contains a watchdog timer that will reset the CPU. This feature means
the AIMB-705 will recover from a software failure or an EMI problem. The JWDT1
jumper settings control the outcome of what the computer will do in the event the
watchdog timer is tripped.

Chapter 1 Hardware Configuration
AIMB-705 allows users to set USB between +5 V_DUAL and +5 V for onboard USB
ports. When the jumper is set as +5 V, the board doesn't support wake up from S3 via
keyboard or mouse.
1.9 System Memory
AIMB-705 has two 288-pin memory sockets for DDR4 1866/2133 MHz memory mod-
ules with maximum capacity of 32 GB (Maximum 16 GB for each DIMM). AIMB-705
only supports non-ECC DDR4 memory modules.
Please note that AIMB-705 does NOT support registered DIMMs (RDIMMs).
* Reset
* default setting
Note! The interrupt output of the watchdog timer is a low level signal. It will be
held low until the watchdog timer is reset.

1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
“open” position. i.e. The handles lean outward. Slowly slide the DIMM module along
the plastic guides on both ends of the socket, and then press the DIMM module right
down into the socket, until you hear a click. This is when the two handles have auto-
matically locked the memory module into the correct position of the DIMM socket. To
remove the memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
