temperature under 0°C (32°F) or above 40°C (104°F), it may damage the
equipment.
8. The openings on the enclosure are for air convection hence protect the equip-
ment from overheating. DO NOT COVER THE OPENINGS.
9. Make sure the voltage of the power source is correct before connecting the
equipment to the power outlet.
10. Place the power cord in a way that people can not step on it. Do not place any-
thing over the power cord. The voltage and current rating of the cord should be
greater than the voltage and current rating marked on the product.
11. All cautions and warnings on the equipment should be noted.
12. If the equipment is not used for a long time, disconnect it from the power source
to avoid being damaged by transient over-voltage.
13. Never pour any liquid into ventilation openings. This could cause fire or electri-
cal shock.
14. Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.

18. This device complies with Part 15 of the FCC rules. Operation is subject to the
following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
19. CAUTION: Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections while the

ACP-2000MB User Manual 6
The following procedures instruct users how to install a motherboard, add-on cards,
and disk drives into the ACP-2000MB. Refer to Appendix A, the Exploded Diagram
and the Parts List for more detailed information about parts for the ACP-2000MB.
2.1 Removing the Top Cover
First, remove the chassis cover by unscrewing six screws, which are on the both
sides and rear location of chassis.
2.2 Installing the Motherboard
The ACP-2000MB can support an ATX motherboard with up to three add-on cards
via the expanded riser card.
To install the motherboard, please proceed as follows:
1. Remove the card holder by loosening the two screws.
2. Attach the motherboard I/O shielding onto the rear plate first. Then fasten the
motherboard onto the chassis.
3. Return the card holder to its original position and fasten it.
4. Connect the 20-pin (or 24-pin) ATX power connector and the 4-pin +12 V power
connector from the power supply to the motherboard.
5. Connect the 9-pin USB wire, PS/2 wire, Power switch wire, and the System
Reset switch wire from the chassis to the motherboard.
Note! Use caution when installing or operating the components with the chas-
sis open. Be sure to turn off the power, unplug the power cord and
ground yourself by touching the metal chassis before you handle any
components inside the machine.
Note! Use caution when installing a motherboard. We highly recommend
choosing a CPU cooler which is lower than 67 mm to avoid component
interference between the motherboard and the chassis, and to ensure
good air flow inside the chassis.

Chapter 2 System Setup
2.3 Installing Add-on Cards
The ACP-2000MB supports up to three add-on cards via the riser card. To install the
add-on cards, please proceed as follows:
1. Remove the corresponding I/O bracket attached to the rear plate of the chassis
(see Figure 2.1). Insert an add-on card vertically into the proper slot on the riser
card. For full-length cards, please make sure that the card bracket has been
inserted properly and the other edge of the card has been inserted into the plas-
tic guiding fillister. Then fasten the screws on the top of the I/O bracket. (see
Figure 2.2)
2. Repeat Step 1 if there is more than one add-on card to be installed.

3.1.2 LED Indicators for System Status
Four LEDs are placed on the left side of the front panel to indicate system health and
activity. Refer to Table 3.1 for an LED definition summary.
When PWR LED turns on, it indicates system power on.
When HDD LED turns on, it indicates HDD data access.
When FAN LED turns RED and blinks, it indicates a failing cooling fan. An alarm is
also activated. To stop the alarm buzzer, press the alarm reset button then replace
the fan with good one immediately.
When TEMP LED turns RED and blinks, it indicates system detects rising tempera-
ture inside the chassis. An alarm is also activated. To stop the alarm buzzer, press
the alarm reset button. Inspect the system components, such as CPU cooler, or fan
filter immediately. Make sure CPU cooler is working fine and airflow inside the chas-
sis is smooth and not blocked with dust or other particles.
